Title: Computation Partitioning in Collaborative Edge Computing



Abstract

Collaborative Edge Computing (CEC) has emerged as a new paradigm for edge computing where the edge nodes of multiple stakeholders are interconnected and collaborate to facilitate the exchange and share of data and joint task execution. In this talk, I will focus on computation partitioning in CEC, which aims to partition and schedule the application tasks between the edge nodes and end devices in order to achieve high performance. I will first define the system model of CEC and two types of collaborations, i.e., horizontal collaboration and vertical collaboration. Then I will discuss the state-of-arts and the challenges. I will also report our recent related works. Specifically, for horizontal collaboration, I will present a novel approach to partition, schedule, and dispatch the tasks in a 5G enabled CEC environment. For vertical collaboration, I will introduce Cooperative Online Schedule, the method we proposed to jointly schedule the tasks and arising data transmissions in CEC. I will conclude the talk by highlighting some future directions on this topic area.

Title: Collaborative Learning towards Real-Time Edge Intelligence



Abstract

The past few years have witnessed the explosive growth of Internet of Things (IoT) devices. Many IoT applications, such as autonomous driving and augmented reality, need intensive computation to accomplish object tracking and intelligent decision in a real-time manner. The necessity of real-time edge intelligence for IoT applications dictates that decision making takes place right here right now at the network edge. Thus motivated, we develop a distributionally robust optimization (DRO) based edge computing framework, aiming to learn the edge model based on local data in real-time, while making use of the trained model in the cloud. Specifically, the knowledge transfer from the cloud to the edge device is in the form of a reference model and its associated uncertainty set, and the edge device further constructs an uncertainty set centered around its local empirical distribution. The edge computing problem is then cast as a DRO problem subject to the two distribution uncertainty sets, and the solution is developed using Optimal Transport Theory.

Title: Indoor Visible Light Communications and Physical-Layer Security Issues



Abstract

Optical Wireless Communications (OWC) and one of its potential applications, Visible Light Comunications (VLC) offer significant technical and operational advantages. With attractive features such as high bandwidth capacity, robustness to electromagnetic interference, high degree of spatial confinement, inherent security and unregulated spectrum, OWC as well as VLC stand out as powerful alternatives and/or complementary technologies to the existing radio frequency (RF) based wireless systems for a wide range of applications. During the past few years, physical-layer security in point-to-point and multiuser VLC network has emerged as a promising approach to complement conventional encryption techniques and provide a first line of defense against eavesdropping attacks. Physical-layer security refers to techniques that exploits channel characteristics in order to hide information from unauthorized receivers, without dependence on upper-layer encryption. Due to its broadcast nature, VLC channels are inherently susceptible to eavesdropping by unintended or unauthorized users who have access to the physical area illuminated by the data transmitters. In this presentation, after a short introduction on VLC, we overview state-of-art techniques employed for physical layer security in VLC systems and introduce two new and novel schemes for VLC physical layer security, based on optical-space-shift-keying (OSSK) modulation and a non-orthogonal multiple access (NOMA) based relay-aided secure broadcasting. In addition, we elaborate a unified information-theoretical framework, relying on the accuracy of the channel estimators, to determine the achievable secrecy capacity and secrecy rate of the proposed schemes.

Title: Doubly-Selective Channel Estimation for Hybrid mmWave Massive MIMO



Abstract

With the unprecedented data rate promises, inherent compatibility with massive MIMO (mMIMO), and FCC authorization underway, mmWave mMIMO has attracted increasing research and development efforts. However, nearly all of these focused on static scenarios, thus excluding mmWave mMIMO deployment in numerous applications on the move, including autonomous driving, HD live streaming, pervasive information showers, and terrestrial-satellite cooperation. This is because the mobility-induced wideband Doppler is not only a challenging problem on its own, but also adds formidable complications to other unprecedented difficulties unique to mmWave mMIMO such as frequency-selectivity with long delay spread due to the Ghz bandwidth, high-dimensionality due to mMIMO, and very few RF chains due to hybrid transceivers. In order to unleash the potential of hybrid mmWave mMIMO for mobile applications, we tackle the doubly-selective channel estimation problem therein. Although this is the very foundation for hybrid mmWave mMIMO system design, there is no reported solution for this to date. In this talk, we will introduce a doubly-selective (DS) channel estimator for hybrid mmWave mmMIMO via innovative exploitation of the double (beamspace and delay-domain) sparsity (DS). Simulations demonstrate that our DS2 estimator achieves ~100% estimation accuracy improvement with 1000-fold storage reduction and 90% computation reduction.

Title: Research Challenges for 5G Cellular Networks



Abstract

Many cities in the world, including Hong Kong, are launching 5G mobile services. Of particular interest are the mmWave bands, which can provide data rates of tens of Gbps due to the employment of advanced networking and communication technology. However, 5G mmWave research is still in its infancy and there are many practical challenges to be addressed before any of the promised benefits can be obtained. Questions that need to be addressed include resource allocation to deal with limited high-frequency channel propagation and high mobility, and energy saving for reducing the huge energy consumption of 5G operation. Drawing upon his experience on the related field, including two recent projects supported by the Hong Kong Innovation and Technology Fund, the speaker will present some research challenges and possible solutions for deploying and operating 5G cellular networks.



Biography:

Dr. Eric Wong has more than twenty years of research experience in the analysis, design and optimization of telecommunications networks, including mobile cellular networks, and the development of accurate and computationally efficient analytical methods for performance evaluation in those networks. One important example is his pioneering work on the Erlang fixed-point approximation (EFPA) for the analysis and design of circuit-switched networks that use dynamic routing. This work has supported a major network evolution implemented by AT&T in the US national telephone network. This includes the first workable analytical method for performance evaluation of state-dependent dynamic routing. The analytical method has significantly reduced the computational effort required and since 1991 has been being used by AT&T to design, dimension and optimize its telephone network that uses Real Time Network Routing (RTNR). Dr. Eric Wong is now an Associate Professor in the Electrical Engineering Department of City University of Hong Kong. His research interests include analysis and design of telecommunications and computer networks, energy-efficient data center design, green cellular networks and optical switching. Recently, Dr. Wong carried out two research projects, supported by the Hong Kong Innovation and Technology Fund, and has been working collaboratively with SmarTone Mobile Communications Ltd, a leading mobile network operator in Hong Kong. One is to develop tools to reduce cellular networks' electricity cost and save energy consumption by switching under-utilized base stations to sleep mode during non-busy hours while the other is to develop novel technologies for 5G base-station deployment.

Title: Beam Tracking for UAV Communications



Abstract

Beam tracking for unmanned aerial vehicle (UAV) communications is an enabling technology that maintains the connection between UAV and ground base stations. In this talk, we propose an efficient training-based beam tracking scheme for UAV system. To track the beam, we need to answer how frequently the training should be performed. The proposed scheme uses joint beam training and angular velocity estimation, based on which the beam coherence time can be obtained. Accordingly, the training frequency can be adjusted based on the variation of beam coherence time. Then, we study the maximization of flying range and speed of UAV. To this end, we optimise the beamwidth by varying levels of hierarchical codebook. For flying range maximization, we first propose an efficient algorithm that can obtain the optimal beamwidth and the corresponding maximal flying range at a given speed of UAV. To gain more insight, we show that in most practical scenarios, the maximal flying range can be achieved with the narrow beam. Furthermore, we show that when the flying range is small, wide beam should be used to support high speed of UAV, and vice versa.
