Title: Recent Advances in Distributed MIMO Transmission Techniques for 5G Mobile Communications
Time: 10:00-10:30, Tuesday, March 6, 2018


Abstract:
The research and development of 5G mobile communications have been intensified. Significantly improving both the spectrum- and energy-efficiencies is demanded for providing enhanced mobile broadband services. One promising approach is the distributed MIMO network (or distributed antenna network) in which a number of antennas are distributed over a macro-cell area to exploit more the spatial distribution of users. In this talk, we will present recent advances in distributed MIMO transmission techniques: single-user STBC-TD, multi-user MMSE-SVD, MIMO channel estimation, and also blind SLM for suppressing the transmit signal PAPR. Although the transmission performance can be significantly improved over a macro-cell area, the cell-edge problem still exists. We will also present an inter-cell interference coordination (ICIC) to overcome this problem in distributed MIMO network.

Title: Energy-Spectral Efficiency Tradeoff for Heterogeneous Networks with QoS constraints
Time: 10:30-11:00, Tuesday, March 6, 2018


Abstract:

In this talk, we will discuss the energy efficiency (EE) and spectral efficiency (SE) tradeoff in multi-cell heterogeneous networks (HetNets). Our objective is to maximize both EE and SE of the network while satisfying the rate requirement of users. We use multi-objective optimization techniques to define the objective function. We propose a three-stage algorithm. First, we select the cell-center radius for the fractional frequency reuse (FFR) method. Second, we assign the frequency resources to satisfy the rate requirements of users and maximize the objective function. Third, the power allocation subproblem is solved by using the Levenberg-Marquardt method. Our numerical results show that a Pareto-optimal solution exists for EE and SE. We present results for different rate constraints.

Danijela Cabric 
Associate Professor, UCLA, USA

Title: Learning Wireless Networks Footprints and Topologies in Shared Spectrum
Time: 11:00-11:30, Tuesday, March 6, 2018


Abstract:
The increasing demand for wireless connectivity and the scarcity of spectrum for exclusive use has popularized the idea of sharing spectrum between multiple communication systems. For a network to estimate its own link budget while avoiding interference from neighboring, or incumbent, networks, it is necessary to learn the spatial, spectral, and temporal usage patterns of its neighboring radios. We begin by proposing algorithms to learn the footprint of each incumbent transmitter, i.e., the sets of CRs that receive signals from that incumbent transmitter. By learning the Gaussian mixture distribution of the received energy vector, we show that multiple transmitters' footprints can be learnt irrespective of their spatial overlap and potentially anisotropic shape. Learning the footprints also enables sampling the activity of each incumbent radio. By identifying radios that transmit as a response to the transmission of another, we learn the causal links between pairs of incumbent radios, i.e., the topologies of the incumbent networks. Thus, we can identify the potential receivers when a particular incumbent radio is transmitting. Hence, we can identify the communication links that can be established without causing interference to the incumbent receivers. Thus, our work is important for the coexistence of communicating networks with arbitrary geographical coverage such as LTE-Unlicensed and WiFi, radars and WiFi, etc. Our inferences can also be used to improve sensing schedules, access strategies, and routing in ad hoc networks.

Title: SmartGeo: Toward the Development of Intelligent Geosystems
Time: 11:30-12:00, Tuesday, March 6, 2018


Abstract:

Earthen dams are critical components in our world's water resource infrastructure, but many are at or near their intended design life. Imagine an earthen dam that monitors itself daily, detects early onset of internal erosion, and takes action to avoid a catastrophic failure. The goal of the SmartGeo program at the Colorado School of Mines is to turn this type of system into reality. We are working to develop intelligent geosystems, in order to enable engineered and natural earth structures and environments to (1) sense their environment and (2) adapt to improve performance.

In this presentation, we will begin with the motivation for our SmartGeo program and the challenges that exist to reach our goal of intelligent geosystems. We will then delve into one specific challenge. Specifically, designing an efficient wireless sensor network capable of real-time, continuous (e.g., 500 Hz sampling rate), geophysical monitoring requires a more intelligent approach than a naive "sense, store, send" method. We, therefore, have been investigating whether compressive sensing techniques are effective with our geophysical data and how we can implement in our resource constrained environment. Our results are promising, and lead us to promote compressive sensing as a useful tool for other wireless sensor network applications.

Professor, University of Paderborn, Germany

Title: Cyber Physical Social Systems: Towards Deeply Integrated Hybridized Systems
Time: 16:30-17:00, Tuesday, March 6, 2018


Abstract:
Research on Cyber Physical Systems (CPS) has led to quite a number of astonishing technical solutions that are becoming standard in many application domains affecting our everyday life. The technical innovations range from control theory concepts to real-time wireless communication to networked control. Some of the most challenging applications include co- operative autonomous driving and industry automation. Despite all these great findings, our research community frequently lost track on the impact of individual human beings that are an integral part of the systems – both as a user as well as a source of disruption. We thus need a paradigm shift from classical CPS to Cyber Physical Social Systems (CPSS). Studying the impact of CPS on humans and vice versa, hybridization, i.e., machines and human users covering parts of the system function in deep interaction, is required as a novel core concept. This is also a basis for final public acceptance as a key to success of new technologies. We investigate these ideas based on the application domain of cooperative autonomous driving and identify core research challenges of such hybridized CPSS.

Professor, University of Minnesota, USA

Title: Learning Nonlinear and Dynamic Network Connectivity and Processes on Graphs
Time: 17:30-18:00, Tuesday, March 6, 2018


Abstract:
Learning the topology of graphs as well as processes evolving over graphs are tasks emerging in application domains as diverse as gene-regulatory, brain, power, and social networks, to name a few. Scalable approaches to deal with such high-dimensional settings aim to address the unique modeling and computational challenges associated with data-driven science in the modern era of big data analytics. Albeit simple and tractable, linear time-invariant models are limited as they are incapable of modeling changing topologies, as well as nonlinear and dynamic dependencies between nodal processes. To this end, novel approaches are presented to leverage nonlinear counterparts of partial correlation and partial Granger causality, as well as nonlinear structural equations and vector auto-regressions, along with attributes such as low rank, sparsity, and smoothness to capture even directional dependencies with abrupt change points, as well as dynamic processes over possibly time-evolving topologies. The unifying framework inherits the versatility and generality of kernel-based methods, and lends itself to batch and computationally affordable online learning algorithms, which include novel Kalman filters and smoothers over graphs. Real data experiments highlight the impact of the nonlinear and dynamic models on gene-regulatory and functional connectivity of brain networks, where connectivity patterns revealed exhibit discernible differences relative to existing approaches.

Distinguished Professor, UCLA, USA

Title: Internet of Vehicles and Autonomous Connected Cars - Privacy and Security Issues
Time: 16:00-16:30, Tuesday, March 6, 2018


Abstract:
In the Intelligent Vehicle Grid, the car is becoming a formidable sensor platform, absorbing information from the environment, from other cars (and from the driver) and feeding it to other cars and infrastructure to assist in safe navigation, pollution control and traffic management. The Vehicle Grid essentially becomes an Internet of Things (IOT), which we call Internet of Vehicles (IOV), capable to make its own decisions about driving customers to their destinations. Like other important IOT examples (e.g., smart buildings), the Internet of Vehicles will not merely upload data to the Internet using V2I. It will also use V2V communications between peers to complement on board sensor inputs and provide safe and efficient navigation. In this paper, we first describe several vehicular applications that leverage V2V and V2I. Communications with infrastructure and with other vehicles, however, can create new problems – privacy and security violations. In the second part of the paper we address these issues and more specifically focus on the need to guarantee location privacy to mobile users. We argue on the importance of creating public, open “smart city” data repositories for the research community and propose privacy preserving techniques for the anonymous uploading of urban sensor data from vehicles.

Title: Tackling Imbalanced Learning in Big Data Era
Time: 17:00-17:30, Thursday, March 8, 2018


Abstract:
Big data has become an important topic worldwide over the past several years. Among many aspects of the big data research and development, imbalanced learning has become a critical component as many data sets in real-world applications are imbalanced, ranging from surveillance, security, Internet, finance, social network, to medical and healthy related data analysis. In general, the imbalanced learning problem is concerned with the performance of learning algorithms in the presence of underrepresented data and severe class distribution skews. Due to the inherent complex characteristics of imbalanced data sets, learning from such data requires new understandings, principles, algorithms, and tools to transform vast amounts of raw data efficiently and effectively into information and knowledge representation to support decision-making process. In this talk, I will start with an overview of the nature and foundation of the imbalanced learning problem, and then focus on the state-of-the-art methods and technologies in dealing with the imbalanced data, followed by a systematic discussion on the assessment metrics to evaluate learning performance under the imbalanced learning scenario. I will also present the latest research development in our group that we have developed and tested on various imbalanced data sets. Furthermore, as a relatively new challenge to the community, I will highlight the major opportunities and challenges, as well as potential important research directions for learning from imbalanced data facing the big data era.

Title: Fundamental Limits on Energy in Wireless Networks
Time: 16:00-16:30, Thursday, March 8, 2018


Abstract:
What is the minimum energy required to transport one bit of information over a wireless network? In this talk we will explore this question from a fundamental information theory point of view. We will discuss how network topology, interference, and cooperation affects energy, and how the information theory insights can be used in designing networks. We will first outline results on the limits of energy per bit in networks when there are no constraints on bandwidth or delay. We will next show how these results change when there is a bandwidth constraint, and show that the effect of interference on energy consumption can be drastically reduced through interference alignment. We will finally show that a delay constraint quite dramatically increases the energy required per bit.

Title: Content-centric Edge Caching for 5G Mobile Internet and Beyond
Time: 17:30-18:00, Tuesday, March 6, 2018


Abstract:
Mobile data traffic is increasing explosively in recent years due to tremendous growth in demands from mobile users for multimedia contents. However, current mobile networking technologies, including network architectures and data transmission techniques, cannot support the anticipated traffic load without degrading mobile user’s QoS/QoE. Much ongoing research efforts are targeted at developing technologies for 5G mobile Internets and beyond to overcome these limitations. Content-centric edge caching has recently emerged as a promising technique to satisfy the demands of popular multimedia contents that are requested repeatedly by multiple mobile users over a period of time. This talk will motivate and explore the design principles and goals of content-centric edge caching. We shall present a generalized architectural framework as a basis of differentiating different edge caching designs. We shall present several trace-driven case studies to illustrate the optimization of some design alternatives. We shall conclude the talk with a discussion of research opportunities and challenges in content-centric edge caching.

Title: The Internet of Things and its Security Challenges
Time: 16:30-17:00, Wednesday, March 7, 2018


Abstract:
Internet of Things (IoT) is an emerging technology that has drawn a lot of attention in recent years. Things in IoT can take a wide variety of forms, from simple RFIDs attached to merchandises, smart thermostats installed in the classrooms, implantable medical devices on the patients, to video cameras on top of light poles, and automobiles with built-in sensors. The explosive deployment of IoTs has pushed the boundary of the cyber-world to be tightly intertwined with our physical world. The IoT enables the exchange of information in a variety of application scenarios, each having unique characteristics and requiring unique performance guarantees, and together they bring potentially tremendous benefits to us- home automation, environmental monitoring, health and lifestyle, smart cities, just to name a few.

Some significant risks go along with the potential benefits of the IoT. As we add devices to our cloths, bodies, homes, and environments, more personal information will be collected. Some information is deeply sensitive. As devices are more closely connected with our physical world and some are capable of taking actions, data security and device security become critically important. Last year, IoT devices have also been exploited to launch the largest DDoS attack in history to disrupt the Internet services.

A secure and trustworthy IoT is not an easy task. It demands multiple lines of defense from different layers to thwart attacks from both the physical world and cyberspace. It also requires the integration of security and privacy mechanisms into computing and networking functions. In this talk, I will introduce the network architecture and unique characteristics of IoT systems. I will then focus on unique security and privacy challenges in the IoT. Many of the security and privacy problems are very challenging and call for interdisciplinary expertise from a number of technical domains.

Title: Modeling resource allocation in cellular networks
Time: 17:00-17:30, Wednesday, March 7, 2018


Abstract:
After cellular network resources are used for a service, they remain allocated to the end user for some time before release, so that if a new service request is generated by the same user, they are immediately available, with no risk of blocking. This behavior differs from the one captured by normal queuing models (for example an M/M/K/0 queue), but it can nevertheless be described with simple networks of queues that yield a closed form expression for the blocking probability. This talk discusses the model development and solution, and compares the model performance predictions to traditional queueing models results, such as the Erlang B formula iteratively applied to the resources that are not blocked by potentially returning users.

Tommaso Melodia (IEEE Fellow)
Associate Professor, Northeastern University, USA

Title: Toward an Optimization-Based Wireless Network Operating System
Time: 17:30-18:00, Wednesday, March 7, 2018


Abstract:
This talk will present the basic design principles for a radically different approach to software-defined networking (SDN) for infrastructure-less wireless networks. Departing from well-understood approaches inspired by OpenFlow, our Wireless Network Operating System provides the network designer with an abstraction hiding (i) the lower-level details of the wireless protocol stack and (ii) the distributed nature of the network operations. Based on this abstract representation, the WNOS takes network control programs written on a centralized, high-level view of the network and automatically generates distributed cross-layer control programs based on distributed optimization theory that are executed by each individual node on an abstract representation of the radio hardware. We will illustrate a prototype implementation of WNOS on software-defined radio devices and test its effectiveness by considering specific cross-layer control problems. Experimental results indicate that, based on the automatically generated distributed control programs, WNOS achieves 18%, 56% and 80.4% utility gain in networks with low, medium and high levels of interference; maybe more importantly, we illustrate how the global network behavior can be controlled by modifying a few lines of code on a centralized abstraction.

Panos Nasiopoulos  (IEEE/CAE Fellow)
Professor, University of British Columbia, Canada

Title: Demystifying High-Dynamic-Range Technology
Time: 16:00-16:30, Wednesday, March 7, 2018


Abstract:
High Dynamic Range (HDR) technology is considered as the next revolution in digital media, as it promises to diligently follow the human visual system (HVS) capabilities in perceiving the world, thus resulting in a viewing experience that closely matches that of the real world. This revolution comes to “disturb” the entire pipeline of digital media representation, affecting capturing, compression, transmission and displaying. HDR image and video technology can capture all the light and color information of a scene, contrary to regular Standard Dynamic Range (SDR) acquisition that can only capture and reproduce a limited dynamic range, brightness and color information present in a real-world scene. These limitations are imposed by capturing and displaying technologies, as well as the representation of pixels throughout the distribution pipeline. While many manufacturers already claim the introduction of HDR-enabled devices, there is still uncertainty around what constitutes HDR, with standardization bodies working hard trying to define its specifications. As exciting HDR may be, it is an emerging technology with its own requirements, challenges, and characteristics. This talk focuses on shedding light on the details behind the HDR technology, including challenges and solutions related to capturing, transmission, and displaying.

Title: Green Robust Optimization for Energy Saving in Networks under Traffic Uncertainty
Time: 16:30-17:00, Wednesday, March 7, 2018


Abstract:
Reducing the energy consumption of communication networks is a major concern for network operators due to economic and environmental reasons. Most of the studies on minimizing the network energy consumption assume the knowledge of the exact traffic matrix, which is the set of traffic demands in the network. There are some works on estimating the traffic matrix, but it remains a difficult and exhaustive task for network operators as it may require each destination Internet Protocol (IP) packets header to be extracted and read. Further, it is more desirable for operators to avoid frequent dynamic route changes according to traffic fluctuation. This talk presents a green robust optimization strategy to achieve power savings in networks under traffic uncertainty. We attempt to achieve a comparable energy efficiency that the schemes based on the knowledge of the exact traffic information.

Title: Spatial Modulation Based on Reconfigurable Antennas – A New Air Interface for the Internet of Things
Time: 17:00-17:30, Wednesday, March 7, 2018


Abstract:
The emerging market of the Internet of Things (IoT) requires new energy-efficient and low-complexity MultipleInput-Multiple-Output (MIMO-) aided radio access technologies. This trend will have a profound impact on both the theory and practice of future communication networks, which will not be purely optimized for approaching the attainable capacity anymore, but will explicitly include the energy efficiency during the design and optimization of the entire protocol stack. In this talk, we put forth a recently introduced modulation scheme for IoT applications, which leverages the concepts of Reconfigurable Antennas (RecAnts) and Spatial Modulation (SM). RecAnt-SM constitutes a promising new air interface in the context of MIMO-aided transmission, which can be beneficially invoked for the design of medium-throughput, low-complexity and energy-efficient communication systems by using a limited number of RF chains and the flexibility of simple RecAnts designs. Theoretical and experimental results will be illustrated.

Title: Cloud Gaming: Improving Quality of Experience with Adaptation and SDN
Time: 10:00-10:30, Thursday, March 8, 2018


Abstract:
While Cloud Gaming was already a US$476 million industry in 2015 and is expected to rise by 28% by 2021 with actual industry products such as Sony’s PlayStation Now, Valve’s Steam, Ubitus’s GameNow, G-Cluster, and LiquidSky, to name a few, its gaming experience still lags traditional console gaming, due to two main reasons: first, the required bandwidth to achieve acceptable playing quality is quite high. For example, just for a 720p video resolution at 50 fps (quite ordinary and near-minimum for today’s gaming standards), Cloud Gaming requires at least 5 Mbps of always-available bandwidth, with 10 Mbs recommended. Second, cloud gaming is very sensitive to network latencies which impair the interactive experience of a game. Studies have shown that Cloud Gaming is currently 1.7 times slower than its console counterpart, a difficult challenge to overcome since only 70% of end-users are able to meet the 100 ms latency target required. In this talk, we present solutions based on Software Defined Networking (SDN) and game adaption that lead to the delivery of higher gaming Quality of Experience by reducing end-to-end delay, jitter, and bandwidth. Our solutions target all layers of a Cloud Gaming system: within the cloud, within the delivery network between the provider and the user, and at the user’s home gateway.

Title: A Fresh Look at an Old Problem: Network Utility Maximization — Convergence, Delay, and Complexity
Time: 10:30-11:00, Thursday, March 8, 2018


Abstract:
Network Utility Maximization has been studied for resource allocation problems in communication networks for nearly two decades. Nonetheless, a major challenge that continues to remain open is how to develop a distributed congestion control and routing algorithm that can simultaneously provide utility optimality, fast convergence speed, and low delay. To address this challenge we take a fresh perspective on this old problem and develop a new algorithm that offers the fastest known convergence speed, vanishing utility optimality gap with finite queue length, and low routing complexity. Our key contributions in this paper are: i) the design of a new joint congestion control and routing algorithm based on a type of inexact Uzawa method in the Alternating Directional Method of Multiplier; ii) a new theoretical pa ath to prove global and linear convergence rate without requiring the full rank assumption of the constraint matrix; and iii) a clear path for implementing the proposed method in a fully distributed fashion.

Title: Gridless Compressed Sensing Meets Phase Retrieval
Time: 11:30-12:00, Thursday, March 8, 2018


Abstract:
Phase retrieval refers to the problem of recovering a signal from only the amplitude of its linear measurements. It appears in a wide range of signal processing applications where sensors cannot measure the phase information (e.g. X-ray imaging, microscopy), or the sampled phase information is polluted by unavoidable and inseparable phase errors (e.g., radar imaging). PhaseLift is a noted convex optimization technique for phase retrieval, but it requires a relatively large number of samples that sometimes can be costly to acquire. In this talk, we exploit salient features of the signals to considerably reduce the number of samples required by PhaseLift. We focuses on some practical applications where the signal of interest is composed of a few Vandermonde components, such as line spectra. A novel phase retrieval framework, namely ANM-PhaseLift, is developed that exploits the Vandermonde structure to alleviate the sampling requirements. The benefit of ANM-PhaseLift is particularly attractive in applications where the Vandermonde structure is presented, such as massive MIMO and radar imaging.

Title: NDN view of the 5G mobile network and IoT
Time: 13:30-14:00, Thursday, March 8, 2018


Abstract:
In this talk I will present how NDN(Named Data Networking), which is an emerging network paradigm and we are one of the active R&D group in this field, is related to the recent 5G mobile network R&D activities, and then which features can contribute to IoT. In the 5G, activities trying to change the basic structure of core network part into more flexible one with the use of slice concept are going on together with the wireless access technology advancement. The 5G mobile network aims to realize enhanced mobile broad band(eMBB), ultra-Reliable low latency communication(URLLC), and massive machine type communication(MMTC) network, and one of the application target area is IoT. To realize low latency, introduction of mobile edge computing is one of the hot topics. These movements are giving the chance of early deployment of emerging network architecture such as NDN and the In-Network data processing concept. On the other hand, NDN can provide with attractive features to IoT use cases. Some typical cases that NDN can provide with benefit will be introduced.

Title: Learning-Based Ultra-Dense Small Cell Networks in Dynamic Environments
Time: 14:00-14:30, Thursday, March 8, 2018


Abstract:
Ultra-dense small cells can achieve high capacity, but pose challenges on managing complicated interference with dynamical traffic patterns and time-varying channels. In this talk we discuss a data-driven bi-adaptive self organizing network (Bi-SON) aiming to improve energy efficiency and reduce interference for ultra-dense small cells by simultaneously considering cell switching on/off, transmission power adjustment, and time-varying channels. We will introduce a Bi-SON testbed at NCTU, of which the experimental results demonstrate an interesting finding -- a data-driven learning performance prediction model can actually help a simple algorithm be upgraded to a powerful adaptation technique in a complex communications environment. As such, the proposed systemic data-driven Bi-SON seemingly shed the light on the research area of wireless QoS when facing even more dynamic and complicated environments. Some interesting research topics extended from this work, such as AI-enabled wireless network on top of Bi-SON, will be also discussed to end this talk.

Title: Resource Allocation for Green Coordinated Multipoint Communication Systems
Time: 17:30-18:00, Thursday, March 8, 2018


Abstract:
Green coordinated transmissions play an important role in development of the next-generation energy- and spectrum-efficient cellular heterogeneous networks (HetNets). On the other hand, by fast evolution of the current power network infrastructure, it is expected that all future communication systems will be powered by a smart grid with high penetration of renewable energy sources (RES). Integration of smart-grid technologies and RES into system designs then holds the key to fully exploiting the potential of coordinated communications in future HetNets. To this end, we establish a new paradigm to develop low-complexity online (real-time) control schemes for efficient utilization of the RES and wireless communication resource. Leveraging the stochastic optimization approach, a unified framework is developed for modeling, analyzing, and designing efficient, robust, distributed, two-timescale online resource management schemes in smart-grid powered coordinated multipoint communication systems. It is shown – both theoretically and empirically- that the proposed algorithms and schemes can significantly improve the energy efficiency of the coordinated communication systems in practical stochastic and dynamic network environments.

Title: Non-Orthogonal Multiple Access in 5G Wireless Networks
Time: 14:30-15:00, Thursday, March 8, 2018


Abstract:
Non-orthogonal multiple access (NOMA) is a spectrally efficient multiple access technique, which has the potential to meet the rapidly increasing traffic demand of the fifth generation (5G) wireless networks. With NOMA, multiple users can be simultaneously served by the same base station via exploiting the power domain in addition to the time and frequency domains. However, by sharing the frequency channel and transmit power among the paired NOMA users, NOMA may not always achieve better performance than orthogonal multiple access (OMA). In this talk, the basic idea of NOMA transmission is firstly discussed. For downlink NOMA transmission with dynamic traffic arrival for spatially random users, two variants of NOMA schemes, i.e., opportunistic NOMA and cooperative NOMA with full-duplex relaying, are proposed to enhance the stable throughput region, which is characterized by using tools from queueing theory and stochastic geometry. Moreover, a dynamic decode-and-forward based cooperative NOMA is also proposed to achieve both superimposed transmission and cooperative diversity in one time slot. Results show that the sum rate of the proposed NOMA scheme over OMA is higher when users having more diverse target data rates are paired.

Title: Optically interconnected resource pool architecture for future backbone network with service scalability
Time: 15:00-15:30, Thursday, March 8, 2018


Abstract:

Service scalability is one of the key issue for future networks. For this, we propose new optical interconnected service function pool architecture having flexibility and high-efficiency. The service scalability is a feature which can create new services with combination of multiple functions. In addition, some functions must be realized by VLSI, FPGA, and software (i.e. NFV) according to their required performance. Software based flexible functions has some advantages that service throughput can be changed by control VM performance. Combination of multiple functions are using by optical interconnection that can relax distance and capacity restrictions among functions that realized by different technologies.

In this talk, we propose a resource pool architecture that all functional resources in the network are called "resource pool". To create the service, proper resources are selected and interconnected by the optical interconnection. In addition, some simulation and prototype study results are also described. The proposed architecture is useful for future backbone networks.

Title: Reliable Video Streaming over mmWave with Multi Connectivity and Network Coding
Time: 16:00-16:30, Wednesday, March 7, 2018


Abstract:
The next generation of multimedia applications will require the telecommunication networks to support a higher bitrate than today, in order to deliver virtual reality and ultrahigh quality video content to the users. Most of the video content will be accessed from mobile devices, prompting the provision of very high data rates by next generation (5G) cellular networks. A possible enabler in this regard is communication at mmWave frequencies, given the vast amount of available spectrum that can be allocated to mobile users; however, the harsh propagation environment at such high frequencies makes it hard to provide a reliable service. This paper presents a reliable video streaming architecture for mmWave networks, based on multi connectivity and network coding, and evaluates its performance using a novel combination of the ns-3 mmWave module, real video traces and the network coding library Kodo. The results show that it is indeed possible to reliably stream video over cellular mmWave links, while the combination of multi connectivity and network coding can support high video quality with low latency.
