Cellular wireless or mobile communications have seen four generations of technological developments. Starting with analog voice with the first, and then moving on to digital voice with the second generation, these generations were each marked with a clear technological advancement. For the third generation, the advancement was in incorporating data on top of a voice-based infrastructure. With the fourth generation, every service was converted into data format, or packetized transmissions, including voice and video. Today, technologists are proposing a fifth generation for around the time frame of 2020. Most consider this time to be when the infrastructure will need to be renewed. Together with this observation, it is usually argued that, the new generation technology should possess a number of features. Yet, there is really no consensus on what these new features should be. Some argue that we are facing a new generation of devices that will have continuous Internet connectivity, and with that there will be more machine to-machine or machine-type communications. It is further argued that, as a result, new communication protocols should be able to support the new formats of communication that this change will require. For example, it is argued that machine-type communication will require very low latency. Others argue that the demand for services will increase by about three orders of magnitude and the new technology should be designed to support this tremendous increase, perhaps handling each order of magnitude by means of a different approach. Yet, there are others who argue that the current communications infrastructure is highly energy-inefficient and the fifth generation should be designed to solve this problem, by increasing energy efficiency by several orders of magnitude. In this talk, we will discuss the pros and cons of the approaches for defining and realizing the fifth generation cellular wireless technologies as seen today. We will discuss what fifth generation can be expected to be and, more importantly, what it cannot be. The goal in this presentation is to form a bridge between the very high expectations and the realities.

Title: CTP-WUR: The Collection Tree Protocol in Wake-up Radio WSNs for Critical Applications

Allowing the nodes of a wireless sensor network (WSN) to turn their radio off periodically noticeably increases network lifetime. Duty cycling, however, does not eliminate idle listening, comes at the price of longer latencies and obtains lifetimes that are still insufficient for many critical applications. Using a wake-up receiver (WUR) allows actual communications on the main radio only for transmission or reception, virtually eliminating node idling. However, the range of current WUR prototypes is still significantly shorter than that of the main radio, which can challenge the use of existing WSN protocols in WUR-based networks. In this paper we present an approach to mitigate this limitation of wake-up-based networks. In particular, we show that the Collection Tree Protocol (CTP), a standard protocol for data gathering in WSNs, suitably redefined to work on WUR-endowed nodes, achieves lifetimes of several decades. This constitutes a remarkable improvement over duty cycle-based solutions, where CTP makes the network lasts only a handful of months. At the same time, our WUR-based approach obtains data latencies comparable to those obtained by keeping the main radio always on.

Title: Software Defined Vehicle Networks (SDVN): Challenges and Opportunities

With the advances of telecommunications, more and more devices are connected to the Internet and getting smart. As a promising application scenario of carrier networks, vehicular communication has enabled many traffic related applications. However, the heterogeneity of wireless infrastructures and the inflexibility in protocol deployment hinder the real world application of vehicular communications. Software defined network (SDN) is promising to bridge the gaps through unified network abstraction and programmability. In this talk, I will introduce an SDN based architecture to enable rapid network innovation for vehicular communications. Under this architecture, heterogeneous wireless devices, including vehicles and roadside units are abstracted as SDN switches with unified interface. In addition, network resources, such as bandwidth, spectrum can also be allocated and assigned by the logically centralized control plane, which provides a far more agile configuration capability. Besides, I will also describe several cases to highlight the advantage of the architecture, such as adaptive protocol deployment, and multiple tenants isolation. Finally, I will discuss the research issues and potential future directions in SDVNs.

Title: Smart Video Streaming Based on User Behavior Analysis

Assuming server bandwidth is the limiting factor, and this bandwidth is charged based on peak load, then a smart bandwidth management strategy (for video streaming) is to apply progressive downloading. Namely, whenever there is extra bandwidth, you let streaming become downloading, to let the streaming users accumulate video content faster than the playback rate, for later consumption. This practice can be significantly improved. For online videos, users tend to browse (rather like channel switching in TV viewing) a lot, and this can lead to downloaded content become wasted. A smart video streaming strategy thus tries to allocate more downloading bandwidth to streaming users who are more likely to continue viewing rather than those who are more likely to quit. This ability can be gained from analyzing user behavior. We describe our work on this topic, including analytical modeling of the situation, as well as experimental results based on real life user behavior traces to demonstrate the benefit of smart video streaming.

Title: Robust Mobile Healthcare System Design

With the emergence of powerful wearable sensors and mobile devices, use of mobile and wireless technologies to support various health related objectives (mhealth) has gained much momentum in the past few years.

Future networks will increasingly become heterogeneous and networks and more highly tuned to achieve much better performance than current architectures (e.g. increase of ~1000 times in data rate even under extreme conditions such as high mobility). These networks will have multiple modalities (wired, wireless, satellite) with disparate channel properties, user rates that range from low to ultra-high (Tbps+) and a wide range of service requirements. Many new network problems that arise in future networks may not be served well by the ~50 year old Internet architecture even with constant evolutions. Increasingly the link layers are very dynamic in their adaptation to rapidly changing environments including both channel properties, achievable rates and offered traffic. When the networks go through a disruptive jump in rates and service quality in the future, they must be built with new innovations in network architectures to drive cost down to affordable levels. Linear extensions of old Internet packet switching architectures and techniques no longer will be the concept that can fully serve future applications. We will explore the properties of emerging applications and identify new architecture techniques and constructs that are based on scientific understandings and optimization of architectures. These techniques need to support new applications such as big data analytics, collaborative sensing and massive data networking in a manner that the network and applications will be aware of each other’s capabilities and available resources, and adaptively and jointly optimize application performance.

Title: Can Wi-Fi and LTE Coexist Fairly in Unlicensed Spectrum?

Unlicensed technologies, mainly Wi-Fi, and licensed cellular technologies, LTE being the latest, have both been enormously successful in their respective domains. However, the ever increasing demands of greater wireless capacity has led to innovative uses of these technologies beyond their original domains. Recent industry trends have moved towards the introduction of LTE, designed for operation over licensed spectrum where interference can be strictly controlled by the operator, into unlicensed spectrum where there is no interference protection by rule. Thus, fundamentally different system architectures: the scheduled, centralized system of LTE and the carrier sense collision avoidance protocol of Wi-Fi will need to coexist "fairly" in the unlicensed spectrum. This talk will provide an overview of recent developments in industry, highlight some of the pressing coexistence issues and propose some solutions that will ensure "fair" coexistence.

Title: Future Distributed Applications Based on Mobile Cloud Computing and Software-Defined Networks

We consider an emerging class of challenging networked applications called Real-Time Online Interactive Applications (ROIA). ROIA are networked applications connecting a potentially very high number of users who interact with the application and with each other in real time, i.e., a response to a user’s action happens virtually immediately. Typical representatives of ROIA are multiplayer online computer games, advanced simulation-based e-learning and serious gaming. All these applications are characterized by high performance and QoS requirements, such as: short response times to user inputs (about 0.1-1.5 s); frequent state updates (up to 100 Hz); large and frequently changing numbers of users in a single application instance (up to tens of thousands simultaneous users).

This talk will address two challenging aspects of future Internet-based ROIA applications: a) using Mobile Cloud Computing for allowing high application performance when a ROIA application is accessed from multiple mobile devices, and b) managing dynamic QoS requirements of ROIA applications by employing the emerging technology of Software-Defined Networking (SDN).

Title: Users Association in Small Cell Networks with Massive MIMO

In this talk, we discuss the recent advance in 5G cellular networks, and concentrate on two specific topics: small cell and massive MIMO. Then we study how the resource allocation should be conducted under those network scenarios. Specifically, the macrocell base station (BS) as well as femtocell access points (FAPs) are equipped with a very large number of antennas. Each mobile user will attempt to connect to the BS or FAPs. However, it is assumed that the users may be biased to connect to FAPs rather than the BS. A resource allocation problem is formulated to find the optimal bias that maximizes the total system capacity while keeping the transmitted power from the BS and the FAPs within a certain limit. An algorithm for solving the optimization problem is proposed and numerical results are presented to illustrate how deploying massive MIMO can affect the optimal bias value and the total capacity. In addition, the performance of our proposed scheme is evaluated when using different precoding schemes.

Title: Green Internet of Things

The Internet of Things (IoT) extends the Internet to connect not only computers and smart devices carried by people, but “things” with embedded sensors, actuators, and networking capabilities. IoT will enable many new services and applications such as smart grids, intelligent transportation, e-health, smart homes/buildings/offices/factories, which will be an integral part of the future smart cities. Of particular interest are applications that contribute to the global efforts towards a greener society by reducing energy consumption, shortening travel times, etc. In many applications, IoT will employ embedded radios and wireless machine-to-machine communications to enable ubiquitous connectivity anywhere any time. Many smart devices with embedded radios are battery operated, and in many situations battery replacement may be awkward if not impossible. Regardless of the power source, with deployment of billions of devices anticipated, global power consumption of IoT may become considerable. Therefore in the continued development of IoT, it is inevitable that energy efficiency becomes an important part of the research agenda towards “green IoT”. In this presentation, we shall give an overview of IoT for smart grids, smart transportation, e-health, smart buildings and smart cities, and examine how IoT contributes to a greener society. We shall also highlight some of our recent research results on utilizing the powerful computation capacity of cloud computing to enable green IoT. Open problems and future research directions will be discussed.

Title: On System-Level Analysis & Design of Heterogeneous Ultra Dense Cellular Networks: The Magic of Stochastic Geometry and the Renaissance of Communication Theory
Time: 11:30-12:00, Tuesday, Feb. 16, 2016

Abstract:

The fifth-generation (5G) is coming. Quo vadis 5G? What architectures, network topologies and technologies will define 5G? Are the methodologies to the analysis, design and optimization of current cellular networks still applicable to 5G? This talk is aimed to discuss the critical and essential importance of spatial models for an accurate system-level analysis and optimization of emerging 5G ultra-dense and heterogeneous cellular networks, which are expected to rely on a much denser deployment of access points, to a scale that has never been observed in the past. Due to the increased heterogeneity and deployment density, in particular, new flexible and scalable approaches for modeling, simulating, analyzing and optimizing cellular networks are needed. Recently, a new approach has been proposed: it is based on the theory of point processes and it leverages tools from stochastic geometry for tractable system-level modeling, performance evaluation and optimization.

In this talk, we investigate the accuracy of this emerging abstraction for modeling cellular networks, by explicitly taking realistic base station locations, building footprints, spatial blockages and antenna radiation patterns into account. More specifically, the base station locations and the building footprints are taken from two publicly available databases from the United Kingdom. Our study confirms that an abstraction model based on stochastic geometry is capable of accurately modeling the communication performance of cellular networks in dense urban environments.

Furthermore, the audience will be introduced to the concept of computational stochastic geometry and to how the mathematical potential of stochastic geometry can be leveraged to an affordable computational complexity, yet retaining its accuracy and capability of modeling practical 5G communication networks. The potential of stochastic geometry for modeling and analyzing cellular networks will be investigated for application to several emerging case studies, including massive MIMO, mmWave communication, and wireless power transfer.

Title: Consideration on Future Network - Towards Realization of Real ICT

Time: 16:00-16:30, Tuesday, Feb. 16, 2016

Abstract:

These days, the environment around communication network is changing rapidly. Main traffic is moving form telephone and mail to video, and the IoT traffic is expected to become one of the major traffics. The nature and usage patterns are very different to each other, and the R&D activities are going on trying to realize new network architecture to efficiently accommodate the traffics. ICN(Information Centric Network) is of the promising architecture, and we are the one who is carrying out an intensive study. We are taking a service oriented R&D, and did the field trial of the proactive caching system which provide comfortable video services to commuter train users based on NDN. Currently, our focus is on IoT services. Majority of current approaches are to carry out information processing at Data center, and the role of networks is just efficient data transmission. This is seen as separated IT and Communication. Trying to make a network fit to the IoT services, we are intending to introduce a in-network information processing by using the basic mechanisms and concepts of NDN, which is in the same direction of Service Centric Networking and Named Function Network proposed. This is the approach to realize real ICT(Information and Communication Technology). In my talk, I will introduce some considerations on the future network, and our service oriented R&D work.

Title: How to Build a Green Internet

Time: 16:00-16:30, Tuesday, Feb. 16, 2016

Abstract:

The world’s cyber infrastructure consumes a small but growing fraction of the global electricity supply. The main consumers of energy are data centers and the global Internet. The total energy consumption of cyber infrastructure is currently dominated by Internet access networks, both wired and wireless. However, the fraction of total energy consumed by routers and switches in the network and by servers in data centres is rising. Servers in data centres could eventually dominate. In this talk, I will examine the key contributors to energy consumption in the Internet and cloud computing, and examine some approaches that will assist in building more energy-efficient infrastructure.

Title: Modeling and Analysis of Co-Existing Multiple Radio Access Technologies in Heterogeneous Wireless Networks

Time: 11:00-11:30, Tuesday, Feb. 16, 2016

Abstract:

In this talk, we present an analytical framework for evaluating the performance of co-existing multiple radio access technologies (RAT) taking into account of the inter-cell interference from the same network as well as other heterogeneous networks (HetNet), the effects of various kinds of multiple access link layer protocols, and the functions of user-cell association algorithms.

Stochastic geometry (SG) is applied in the proposed analytical framework to analyze the performance of multi-tier heterogeneous ultra-dense small cells, and 3GPP long-term evaluation – unlicensed (LTE-U). The proposed analytical framework can provide the important insights into the design of small cell managements in HetNet. We will introduce many important concepts, such as void probability, and energy-efficient cell association from the holistic viewpoint of energy efficiency and spectrum efficiency, and overall of load balancing of multi-RAT systems. Last, we well highlight some research directions for modeling, analysis and design for the co-existing multi-RAT systems in HetNet.

Title: Application of Data Analytics: Security and Privacy in Social Networks

Today's online social networks have pervaded all aspects of our daily lives. With their unparalleled popularity, online social networks have evolved from the platforms for social communication and news dissemination, to indispensable tools for professional networking, social recommendations, marketing, and online content distribution. Their evolution has influenced every technological, societal, and cultural aspect of human beings. They are receiving more and more attention in research communities.

It has been widely recognized that security and privacy are the critical issues in online social networks. On one hand, online social networks have been the effective platform for the attackers to launch attacks and distribute malicious information. On the other hand, privacy leakage through online social networks has become common exercise. New methods and tools, consequently, must follow up in order to adapt to this emerging security paradigm. In this talk, we will discuss the security and privacy problems in social networks and how big data analytics can be used to address the problems.

Title: A Stochastic Analysis of Network MIMO Systems

Network MIMO, where base-stations (BSs) cooperatively transmit and receive to/from the users, promises to significantly alleviate the inter-cell interference problem in wireless cellular networks; but its analytical performance characterization is still a difficult open problem. In this talk, we describe a stochastic geometry analysis of a network MIMO system, where the multiple-antenna BSs are distributed according to a Poisson point process and cooperate using zero-forcing beamforming to serve multiple users. We obtain tractable and accurate approximations of the signal power and inter-cluster interference power distributions, and derive a computationally efficient expression for the achievable per-BS ergodic sum rate. The analysis enables us to obtain the optimal number of users to schedule and to quantify the performance improvement of network MIMO systems as a function of the cooperating cluster size. We show that due to the zero-forcing penalty across a distributed set of BSs and the inevitable out-of-cluster interference that always exists, the per-BS ergodic sum rate of a network MIMO system does not approach that of an isolated cell even at unrealistically large cluster sizes. Finally, we illustrate the benefit of user-centric clustering for cell-edge users, and remark on a comparison between massive MIMO and network MIMO systems and a tradeoff between spatial multiplexing and interference nulling.

Title: COBANETS: A New Paradigm for Cognitive Communications Systems

Time: 11:00-11:30, Tuesday, Feb. 16, 2016

Abstract:

In response to the new challenges in the design and operation of communication networks, and taking inspiration from how living beings deal with complexity and scalability, in this position paper we introduce an innovative system concept called COgnition-BAsed NETworkS (COBANETS). The proposed approach develops around the systematic application of advanced machine learning techniques and, in particular, unsupervised deep learning and probabilistic generative models for system-wide learning, modeling, optimization, and data representation. Moreover, in COBANETS we propose to combine the learning architecture with the emerging network virtualization paradigms, which make it possible to actuate automatic optimization and reconfiguration strategies at the system level, thus fully unleashing the potential of the learning approach. Compared to past and current research efforts in this area, the technical approach depicted in this paper is deeply interdisciplinary and more comprehensive, calling for the synergic combination of expertise of computer scientists, communications and networking engineers, and cognitive scientists, with the ultimate aim of breaking new ground through a profound rethinking of how the modern understanding of cognition can be used in the management and optimization of telecommunication networks.
