Title: Massive MIMO with Spatially Correlated Antennas
Time: 10:00-10:30, Tuesday, February 18, 2020.

The analysis of a single-carrier massive MIMO system for the frequency selective Gaussian multiuser channel in uplink and downlink directions is presented. Expressions for the achievable sum rate when there is spatial correlation among antennas at the base station is carried out. It is known that the channel matched filter precoder (CMFP) performs the best in a spatially uncorrelated downlink channel. We show that, in a spatially correlated downlink channel with two different correlation patterns and at high long-term average power, two other precoders can have better performance. For the uplink channel, part of the equivalent noise in the channel goes away, and implementing two conventional equalizers leads to a better performance compared to the channel matched filter equalizer (CMFE). These results are verified for uniform linear and uniform planar arrays. In the latter, due to more correlation, the performance drop with a spatially correlated channel is larger, but the performance gain against channel matched filter precoder or equalizer is also bigger. In highly correlated cases, the performance can be a significant multiple of that of the channel matched filter precoder or equalizers.

Title: Recent Progress on the Wireless Power Harvesting and Transfer for Communications
Time: 10:00-10:30, Thursday, February 20, 2020

Electromagnetics is the foundation of modern electrical and computer engineering that realize electrical and electronic technologies we enjoy and take for granted today. It has been used to transfer information and power in daily lives. In the wireless domain, however, it had not been considered and employed much for energy harvesting and power transfer until 2008 when a MIT research team lead by Prof. Marin Soljacic successfully demonstrated the mid-range wireless power. Research and development of wireless power harvesting and transfer systems have since attracted much attention for their potentials in changing the ways we live and work. At the same time, the internet-of-things and its applications will become so prevalent that large numbers of sensors will be required and efficient and effective power supply to them will become a challenge. In this presentation, we will review the principles of the wireless power harvesting and transfer, the state-of-the-art, their applications in communications and the future directions. In particular, we will focus on the physical constraints of the wireless power technologies, the potential solutions to them, simultaneous wireless information and power transfer technologies and the relevant safety issues.

Title: Machine Learning Meets Wireless Network Optimization: Exploring the Latent Knowledge
Time: 16:00-16:30, Thursday, February 20, 2020

With the superior capability of discovering intricate structure of large data sets, deep learning has been widely applied in various areas including wireless networking. While existing deep learning applications mainly focus on data analysis, the role it can play on fundamental research issues in wireless networks is yet to be explored. With the proliferation of wireless networking infrastructure and mobile applications, wireless network optimization has seen a tremendous increase in problem size and complexity, calling for a paradigm for efficient computation. This talk gives our recent studies on how to exploit deep learning for significant performance gain in wireless network optimization. Analysis on the flow constrained optimization problems suggests the possibility that a smaller-sized problem can be solved while sharing equally optimal solutions with the original problem, by excluding the potentially unused links from the problem formulation. To this end, we design a deep learning framework to find the latent relationship between flow information and link usage by learning from past computation experience. Numerical results demonstrate that the proposed method is capable of identifying critical links and can reduce computation cost by up to 50% without affecting optimality, thus greatly improve the efficiency of solving network optimization problems.

Professor, University of Paderborn, Germany

Title: Integrating Haptic Signals with V2X-based Safety Systems for Vulnerable Road Users
Time: 10:30-11:00, Thursday, February 20, 2020

We study Vehicle to Everything (V2X)-based road traffic safety systems for Vulnerable Road Users (VRUs), particularly focusing on cyclists. The development of Advanced Driver Assistance Systems (ADAS) is usually first done with the help of computer simulation. For VRUs, this lacks suitable mobility models. Furthermore, real-world experimentation is often infeasible due to the immediate danger the test participants would be put into. As a solution, we propose a human-in-the-loop approach. We extended our Virtual Cycling Environment (VCE) to integrate a variety of signals to inform a cyclist riding a real bike on a training stand in a simulated 3D traffic scenario. A particular focus was put on haptic signals, which seem to be best suitable in complex traffic situations.

Title: UAV Applications over Cellular Networks: Sensing, Communication, and Control
Time: 16:00 - 16:30, Wednesday, February 19, 2020

The emerging unmanned aerial vehicles (UAVs) have been playing an increasing role in the military, public, and civil applications. Very recently, 3GPP has approved the study item on enhanced support to seamlessly integrate UAVs into future cellular networks. Unlike terrestrial cellular networks, UAV communications have many distinctive features such as high dynamic network topologies and weakly connected communication links. In addition, they still suffer from some practical constraints such as battery power, no-fly zone, etc. As such, many standards, protocols, and design methodologies used in terrestrial wireless networks are not directly applicable to airborne communication networks. Therefore, it is essential to develop new communication, signal processing, and optimization techniques in support of the ultra-reliable and real-time sensing applications, but enabling high data-rate transmissions to assist the terrestrial communications in LTE. In this talk, we discuss three scenarios: First, for UAV sensing applications, we obtain realtime profiling of fine-grained air quality index distribution using sparse optimization techniques. Second, for UAV communication scenarios, we conduct spectrum sharing planning for UAV relaying systems to enhance 5G communications. Finally, to control a large number of UAVs, we propose mean field game approaches.

Title: Machine Learning Aided Mobile Edge Computing in Blockchain Based Vehicular Networks
Time: 11:30-12:00, Tuesday, February 18, 2020

This work studies machine learning aided communication and computation resource allocation in the vehicular network that supports the blockchain-enabled video streaming. We aim for achieving the operating efficiency and maximizing the transcoding rewards for the blockchain networks. Moreover, the resource allocation policy is designed by considering the vehicular mobility and the hard real-time service deadline constraint. We propose to use actor-critic-reinforcement learning with the multi-timescale framework to tackle these grand challenges in this work. We also develop the prediction model for the vehicular mobility by using semantic analysis and the classical machine learning mechanism, which alleviates the heavy signaling and computation overheads due to the vehicular movement. We furthermore devise the mobility-aware reward estimation for the large timescale model to mitigate the complexity due to the large action space. Numerical results are presented to illustrate the theoretical findings developed in this research r and to quantify the performance gains attained.

Title: AIoT as a Service - Opportunities and Challenges
Time: 16:30-17:00, Tuesday, February 18, 2020

With the increasing adoption of Internet of Things (IoT) and rapid advancements of Artificial Intelligence (AI) applications, the integration of AI and IoT, widely referred as AIoT, is gaining momentum. Realizing AIoT will require massive investments in infrastructure, and lessons learned from network deployments point to the use of shared hardware and software resources that can be virtualized to support various services on demand, thus AIoT-as-a-Service (AIoTaaS). In this talk, we start with a review of the idea of Anything-as-a-Service (XaaS), leading to IoTaaS and AIaaS, which form the basis of AIoTaaS. We present a framework for AIoTaaS, which incorporate edge and cloud computing platforms to support the AI functionalities required for different services. Enabled by cloud and edge computing, AIoTaaS can effectively implement machine learning (ML) training and inference functions on cloud and edge devices with much less complexity to enable efficient and effective AI decision making in IoT and data analytics, especially in the area of streaming data and real-time analytics associated with edge computing networks. To implement AIoTaaS, interoperability between components at the device level, software level and platform level should be extended while optimizing system and network operations as well as extracting value from data. In the future, AIoTaaS integrated with 5G and blockchain will be leveraged to achieve more efficient IoT operations, improve human-machine interactions and enhance data management and analytics, creating a foundation for pervasive AI services and applications.

Title: 5G Mobile Edge Computing: Research Roadmap on Routing, Offloading, Slicing, Federation, and Optimization
Time: 17:00-17:30, Tuesday, February 18, 2020

5G promises to deliver enhanced mobile broadband (eMBB), massive machine type communication (mMTC), and ultra reliable low latency communication (URLLC). To support mMTC and URLLC, 5G needs to carry out computations closer to subscribers at the “edge” instead of the cloud, which turns 5G into an infrastructure for both communication and computing. Just like cloud computing, edge computing shall also be virtualized. On the other hand, communication is also being virtualized with software defined networking (SDN) and network function virtualization (NFV) which virtualize control plane and data plane, respectively. When applied to 5G, together they virtualize functions in access and core networks, and release them to run on any virtualized computing platform. Combining virtualization needs in edge computing and communication, 5G mobile edge computing (MEC) is virtualizing eNB (evolved node B), EPC (evolved packet core), and CO (central office) into VeNB, vEPC, and CORD (central office re-architected as a datacenter). They are not just communication devices anymore, but also serve as computing datacenters with many open source resources like OpenDaylight and OpenStack. After streamline the above evolution path, we then give an overview of research roadmap on 5 key components, including service chain routing, multi-RAT offloading, multi-tenant slicing, horizontal and vertical federation, and capacity optimization. Selected results are then presented.

Title: Cross-Layer Strategic Ensemble Defense Against Adversarial Examples
Time: 11:00 - 11:30, Tuessday, February 18, 2020

Deep neural network (DNN) has demonstrated its success in multiple domains. However, DNN models are inher- ently vulnerable to adversarial examples, which are generated by adding adversarial perturbations to benign inputs to fool the DNN model to misclassify. In this paper, we present a cross-layer strategic ensemble framework and a suite of robust defense algorithms, which are attack-independent, and capable of auto-repairing and auto-verifying the target model being attacked. Our strategic ensemble approach makes three original contributions. First, we employ input-transformation diversity to design the input-layer strategic transformation ensemble algorithms. Second, we utilize model-disagreement diversity to develop the output-layer strategic model ensemble algorithms. Finally, we create an input-output cross-layer strategic ensemble defense that strengthens the defensibility by combining diverse input transformation based model ensembles with diverse output verification model ensembles. Evaluated over 10 attacks on ImageNet dataset, we show that our strategic ensemble defense algorithms can achieve high defense success rates and are more robust with high attack prevention success rates and low benign false negative rates, compared to existing representative defenses.

Title: RFID based Vital Sign Sensing and Its Application to Driving Fatigue Detection
Time: 16:00-16:30, Tuesday, February 18, 2020

Abstract: With the rapid development of intelligent health sensing in the Internet of Things (IoT), vital sign monitoring (e.g., respiration) and abnormal respiration detection have attracted increasing attention. Considering the challenges and the cost of collecting labeled training data from patients with breathing related diseases, we develop the AutoTag system, an unsupervised recurrent variational autoencoder-based method for respiration rate estimation and abnormal breathing detection with off-the-shelf RFID tags and reader. Moreover, for real-time breath monitoring, a novel method is proposed to cancel the distortion on measured phase values caused by channel hopping for FCC-complaint RFID systems. We will also show how to apply RFID based sensing for an effective, low-cost driving fatigue detection system, such as detecting the nodding movements or the respiration rate of the driver, both in the highly noisy driving environment. The accurate detection performance of the proposed systems is validated by our experimental study.

In this talk we discuss some very simple Radio Access Network configurations comprising one macro cell and one or two small cells, the latter being strategically positioned to absorb the traffic peaks that occur in portions of the area covered by the macro cell. We study these configurations with simple models, and we examine the system performance for variable parameter values, showing that some of the emerging behaviors can be critical, but can provide insight for the small cell deployment. In particular, we show that when the handover rate out of the small cells toward the macro cell increases, the blocking probability in the macro cell also increases, quickly reaching unacceptable levels. This can be a problem, since high handover rates correspond to limited dimensions of the small cell with respect to the macro cell, which is what is normally expected, unless the small cell is deployed in an area of very slow end user mobility.

Title: P2P network issues in a blockchain-based ledger
Time: 16:30-17:00, Wednesday, February 19, 2020

Interconnection network and its performance have a major impact on the performance of blockchain-based distributed ledgers. In this talk, we present a brief overview of the Bitcoin's blockchain distribution network, followed by a model of the data distribution algorithm, and some performance results pertaining to block and transaction propagation times, fork probability, network partitioning in case of a fork event, and duration of the inconsistent state of the ledger. Values of individual model parameters are derived from recent measurements and business analysis reports. We model the data distribution algorithm using branching processes in the network with random distribution of node connectivity. Then we apply Jackson network model to the entire network in which individual nodes operate as priority M/G/1 queuing systems. Data arrival to the nodes is modeled as a non-homogeneous Poisson process where the distribution of arrival rate to the nodes is derived from the analytical model of data delivery protocol. We show that the three-way forking probability is substantially lower than that of a two-way forking and that the partition sizes in the case of two-way forking tend to equalize when the number of nodes increases. We also show that the duration of ledger inconsistency state exhibits long tail probability distribution which means that successive forking events can force the ledger to remain inconsistent for a long time.

Title: A Quest for the perfect picture: Recreating the “Holodeck”
Time: 13:30-14:00, Thursday, February 20, 2020

Light is crucial to our ability to perceive and successfully interact with our environment. As rays of light reach our eyes from every possible direction, either directly from the source or reflected off of objects and surfaces, they excite our visual system, which translates them to spatial, temporal, textural/colour-gamut information. Conventional visual capturing technologies are unable to fully acquire these properties, necessary to mimic human perception. In particular, traditional technologies have been limited to capturing only the sum total intensity of light rays striking every point in the targeted space. This is far from the visual world as perceived by humans, as we need somehow to capture light intensity and direction as well as the exact placement of every point in space along with other relevant visual and situational cues. In this talk, we will discuss ways for acquiring human-like visual data that may allow ultimate replication of our visual environment, closely mimicking human perception. Then we will examine how such information can drastically affect domains that depend heavily on visual acquisition technologies, such as entertainment/education & training, autonomous driving, highly immersive Virtual Reality (VR) and Augmented Reality (AR) & gaming education/training, Digital health and wellness.

Title: Smart Service-Aware Wireless Networks
Time: 10:30 - 11:00, Tuesday, February 18, 2020

Smart services such as smart home, smart grid, smart transportation, and so on, are enabled with advanced communications networks, data analysis and control. However, challenges exist in designing a supporting network with optimal resource management while achieving quality- of-experience for a smart service. In this talk, we present a unified Smart Service-Aware Wireless Mixed-Area Networks (SA-WMN) architecture that can be applied to different smart services. The core of the SA-WMN architecture is a smart service-aware network controller. The mega network controller has a service adaptation module, network cognition module and resource provisioning module that can achieve cost-effective wireless-mixed area network deployment, and efficient network resource management of SA-WMN. The proposed SA-WMN architecture is expected to close the gap on wireless network design, improve energy efficiency and enhance spectrum efficiency and access, in a smart service- aware paradigm. It will pave the way for realizing next-generation wireless network based smart services.

Title: Study of a Unified High-Speed Wireless Communications Architecture for High-Speed Rail Networks
Time: 17:30-18:00, Wednesday, February 19, 2020.

High-speed trains, though prevalent in Europe and Asia, are not yet a reality in the US. Interests and industry engagements are growing, especially around commercial hubs close to commuter homes for alleviating commute times and cost. With support from the US Federal Railroad Administration (FRA) in the Department of Transportation (DoT), Dr. Sharif’s team has explored the design requirements, challenges, and technology capabilities for high-speed wireless communications for high-speed trains using the next-generation radio access technologies. A safe, secure, efficient and seamless train operation moving underground or over at a regular or high speed (around 300 km/h) requires reliable wireless communications. The wireless communications to support in-train passenger services, train signaling and controlling services necessitate challenging considerations regarding wireless channel conditions and communications management, especially considering movement through different terrain environments (hills, flat-rural, urban-dense, etc.) and railroad infrastructure (bridges, viaduct, tunnel). These scenarios cause difficult channel conditions to manage, specifically for channel requirements for a train-to-ground Radio Access Networks. Dr. Sharif will discuss the technical challenges for this unified wireless architecture including modeling and simulations as well as insights into evaluated properties of this system.

Title: On the Connectivity of Drones to Mobile Networks
Time: 16:30-17:00, Tuesday, February 18, 2020

Low-flying drones have started to be deployed commercially for product delivery and are being proposed for a large number of applications, from search and rescue to the inspection of power lines. They also have the potential to augment or provide wireless service in locations of suddenly increased demand for connectivity (e.g., outdoor concerts, demonstrations, disaster sites). Our recent work explores the issue of connectivity of drones to the ground network infrastructure, as well as their potential to provide service to users on the ground. Our models employ stochastic geometry to quantify the connectivity conditions under different scenarios for the drones (flying height, directional transmission capabilities) and the ground infrastructure (density of buildings, antenna tilt). We are also exploring the use of machine learning to dynamically assess these factors and make resource management decisions in drone connectivity.

Title: Spatial Sigma-Delta ADCs: A Low Complexity Architecture for Massive MIMO
Time: 14:30-15:00, Thursday, February 20, 2020

Low-resolution sampling has been extensively studied as a method for reducing the hardware complexity of communications systems with large numbers of antennas. While one-bit quantization yields the best energy efficiency, its severe non-linearity has a significant impact on performance. Borrowing from the idea of one-bit Sigma-Delta oversampling in the temporal domain, we describe a corresponding technique in the spatial domain, in which the quantization noise is shaped away from the signal directions corresponding to users of interest. This talk discusses various aspects of the spatial Sigma-Delta architecture, including channel estimation, input amplitude scaling, impact of mutual coupling with oversampled arrays, number of bits of resolution, and performance relative to other methods. We show that for scenarios typical in cellular systems, where the users are confined to an angular sector, the one-bit Sigma-Delta approach can provide performance approaching that of a system with high-resolution ADCs, with significantly lower hardware complexity.

Title: Towards Smart and Secure Connected Health
Time: 17:00-17:30, Thursday, February 20, 2020

Connected health is the use of Internet, sensing, communications and intelligent techniques in support of healthcare applications.

Title: AI-Assisted Text Mining and Document Engineering to Facilitate Reading for Understanding
Time: 17:00-17:30, Wednesday, February 19, 2020

Reading is fun, until it becomes a chore. Remember the time when we have to read a pile of research papers and make a presentation next Monday? Reading is a basic skill with three purposes: (1) Read for entertainment; (2) Read for information; (3) Read for understanding (of knowledge). Linear reading from the beginning to the end is the norm. Is there a better way to read for understanding? Let’s think outside the box and turn linear reading to hierarchical reading over a digital platform. Imagine that we have access to an oracle that ranks the sentences of the given text according to their importance, allowing us to read blocks of sentences one at a time in descending order of importance, focus on the most important block of sentences, and read subsequent blocks to strengthen understandings of earlier blocks. Moreover, the oracle also generates questions and evaluates answers. We present an AI-assisted text mining oracle to facilitate reading for understanding with the following requirements: Accurate and Efficient for the oracle and Effective for the reader. In particular, we present an sentence ranking algorithm called Semantic SentenceRank (SSR) that incorporates word and phrase co-occurrences, semantic relations over word embeddings, semantic sentence relations over word embedding mover’s distance, article structure-biased PageRank, softplus elevation, and sentence selection according to topic clustering distribution. We show that SSR outperforms individual human judges over the SummBank benchmarks and compares favorably with the combined rankings of all three judges. We will also show how to use document engineering to handle two-column pdf documents for SSR. To demonstrate efficiency and effectiveness, we will provide a live demo of the system.

Title: Interference Management for Future Cellular Mobile Networks: From Unsupervised Learning to Deep Reinforcement Learning
Time: 10:00-10:30, Tuesday, February 18, 2020

The dense deployment of small cells in 5G cellular networks and drone base station raises the issue of controlling downlink inter-cell interference and based station energy saving under time-varying channel states. In this talk, we first demonstrate that the inter-cell interference can be used to describe the affinity of cells, and then introduce an unsupervised learning algorithm for ultra-dense small cells (UDSC) based on an affinity propagation clustering approach. In principle, the proposed affinity propagation power control (APPC) first groups small cells into different clusters and identifies cluster centers. Next, the transmission power of a cluster center is decreased to reduce the interference to the neighboring cells’ users in this cluster. Secondly, we extend the proposed APPC algorithm to the scenario with drone base stations, for which energy saving is a critical issue. We find that APPC can not only control the inter-cell interference effectively, but can help save energy consumption of base stations by taking advantage of the reposition capability of drone base stations. Thirdly, we introduce two reinforcement learning approaches to suppress inter-cell interference and save energy for UDSC: Q-learning and deep reinforcement learning. Analytical convergence performance bounds, including throughput, energy consumption, inter-cell interference, and the utility of base stations are discussed. Last, we highlight the research issues that merit attention in the future development of artificial intelligence and machine learning for future cellular mobile networks.

Title: DCWiz: Transforming Data Center Operations and Management (O&M) with AI
Time: 11:30-12:00, Thursday, February 20, 2020

Data center, dedicated space to house IT equipment, plays an important role in propelling digital transformation globally. The resulted extensive use of services such as cloud, big data, IoT and artificial intelligence is prompting DC operators to consolidate high-performance mission critical IT infrastructure in hyper-scale data centers. In practice, data centers are managed and optimized towards two operational objectives: 1) business continuity, serving to evaluate the commercial impact of service disruption, and 2) energy efficiency, serving to evaluate the cost of providing services. AI solutions, made popular by Google DeepMind, have been touted with great potential to optimize the aforementioned operational metrics. However, adopting AI techniques for data center operations and management (O&M) faces substantial challenges in data availability and deployment inhibitors. In this talk, we present DCWiz, a transformative solution that integrates an industry-grade digital twin with emerging AI techniques to optimize and automate data center O&M for business continuity and energy efficiency. Specifically, DCWiz leverages advanced AI techniques (e.g., deep reinforcement learning and generative adversarial network) to train an industry-grade digital twin for any physical data center, in terms of data accuracy, and deploy the digital twin as a pivotal module to provide descriptive, predictive and prescriptive AI for DC O&M. We also share three commercial trials with Alibaba, Singapore National Supercomputing Center (NSCC) and a commercial bank, each of which represents different applications of the DCWiz solution. The trial results demonstrate the effectiveness of our DCWiz solution in improving manageability, reducing cost and mitigating operational risks for mission-critical data centers.

Title: Satellite Communication at Millimeter Waves: a Key Enabler of the 6G Era
Time: 10:30-11:00, Tuesday, February 18, 2020

While technical standard development for 5G radio services is still an ongoing process, the scientific community is drafting the key drivers, requirements, challenges and re- search questions towards 6th generation (6G) networks. 6G developments will foster, among other innovations, the evolution of wireless systems towards a 3D, continuous and ubiquitous service coverage by complementing terrestrial networks with computing stations placed on satellite platforms. Along these lines, in this paper we demonstrate the feasibility of using millimeter wave (mmWave) frequencies to establish high-capacity satellite communications, in view of the huge traffic demands and service continuity requirements of forthcoming 6G applications. We also identify the most promising configuration(s) for satellite networking and discuss the design trade-offs in this domain.

Title: Scalable and Accurate Modeling of the Millimeter Wave Channel
Time: 17:30-18:00, Thursday, February 20, 2020

Communication at millimeter wave (mmWave) fre- quencies is one of the main novelties introduced in the 5th generation (5G) of cellular networks. The opportunities and challenges associated with such high frequencies have stimulated a number of studies that rely on simulation for the evaluation of the proposed solutions. The accuracy of simulations largely depends on that of the channel model, but popular channel models for mmWaves, such as the Spatial Channel Models (SCMs), have high computational complexity and limit the scal- ability of the scenarios. This paper profiles the implementation of a widely-used SCM model for mmWave frequencies, and proposes a simplified version of the 3GPP SCM that reduces the computation time by up to 12.5 times while providing essentially the same distributions of several metrics, such as the Signal-to- Interference-plus-Noise Ratio (SINR) in large scale scenarios. We also give insights on the use cases in which using a simplified model can still yield valid results.
