Abstract: Millimeter wave (mmWave) communications is viewed as the key enabler of 5G cellular networks due to vast spectrum availability that could boost peak rate and capacity. Due to increased propagation loss in mmWave band, transceivers with massive antenna array are required to meet link budget. While massive antenna arrays enable high gain, directionality and user multiplexing, practical realizations face many challenges in radio design and physical layer processing. In this talk, we first review emerging massive array architectures for mmWave communications and compare their performance, power consumption, and cost with comprehensive hardware block model under typical application use cases. We then discuss two important physical layer design aspects in mobile mmWave networks: directional link establishment via initial access and directional link maintenance via mmWave channel tracking. Lastly, we present the state-of-the-art designs of current mmWave standards, discuss their limitation and provide perspectives on innovative approaches for performance boosts and hardware improvements.

Abstract: Adaptability and advanced services for ambient intelligence require an intelligent technological support for understanding the current needs and the desires of users in the interactions with the environment for their daily use, as well as for understanding the current status of the environment also in complex situations. This infrastructure constitutes an essential base for smart living. Computational intelligence can provide additional flexible techniques for designing and implementing monitoring and control systems, which can be configured from behavioral examples or by mimicking approximate reasoning processes to achieve adaptable systems. This talk will analyze the opportunities offered by computational intelligence to support the realization of adaptable operations and intelligent services for smart living in an ambient intelligent infrastructure.

Abstract: I will describe our recent experience of implementing a news content organization system in collaboration with Tencent that can discover hot events from vast streams of breaking news and connect events into stories for easy viewing. Our real-world system has distinct requirements in contrast to previous studies on document topic modeling and detection, in that 1) an event does not only contain articles of a similar topic, but is a cluster of documents that report exactly the same physical incidence; 2) we must evolve news stories in a logical and online manner. In solving these challenges, we propose Story Forest, a state-of-the-art news content organization system based on artificial intelligence and natural language processing. I will briefly describe the key enabling technologies in Story Forest, including identifying the relationship between text objects, e.g., whether they talk about the same event or whether one article is a follow-up of another, based on deep learning. Our system has been deployed in Tencent QQ Browser mobile app.

Abstract: To stabilize output variability of distributed renewable energy sources (RESs), integrating large-scale RESs is highly utilized, and aggregated RESs are treated almost as any other conventional generators in existing electricity markets. In this talk we first propose a coalitional framework to cope with the uncertainty of RESs when RES owners can participate in a wholesale electricity market as sellers, where a market operator financially penalizes RES owners for deviations between day-ahead and real-time markets. Our theoretical approach incentivizes participants in a coalition by mitigating penalty fees caused by renewable variability. Furthermore, we propose a bidding strategy called Gaussian residual bidding (GRB) to maximize a coalition gain of participants. We prove that the considered game is convex game when GRB is used for all participants. Our extensive simulations with real data demonstrate that the proposed bidding strategy combined with the coalitional framework outperforms other bidding strategies as well as non-coalition cases under various market scenarios. Our results exhibit the revenue of GRB is improved up to 200% compared to the existing empirical quantile bidding and forecast bidding strategies.

Title: EdgetIoT: Mobile Edge Computing for the Internet of Things
Presented by: Prof. Nirwan Ansari, New Jersey Institute of Technology, USA
IEEE Communications Society Distinguished Speaker
Abstract: In order to overcome the scalability problem of the traditional Internet of Things (IoT) architecture (i.e., data streams generated from distributed IoT devices are transmitted to the remote cloud via the Internet for further analysis), mobile edge computing has been proposed to provision IoT by handling the data streams at the mobile edge. Specifically, each base station is connected to a fog node, which provides computing resources locally. On the top of the fog nodes, the software defined networking (SDN) based cellular core is designed to facilitate packet forwarding among fog nodes. Meanwhile, we propose a hierarchical fog computing architecture in each fog node to provide flexible IoT services: each user’s IoT devices are associated with a proxy VM (located in a fog node), which collects, classifies, and analyzes the devices’ raw data streams, converts them into metadata, and transmits the metadata to the corresponding application VMs (which are owned by IoT service providers). Each application VM receives the corresponding metadata from different proxy VMs and provides its service to users. In addition, a novel proxy VM migration scheme is proposed to minimize the traffic in the SDN-based core.

Title: Molecular Communication: From Theory to Practice
Presented by: Prof. Andrew Eckford, York University, Canada
Abstract: How can we communicate using molecules? This question may unlock new applications in nanorobotics and medicine, but has only recently attracted attention from communication and information theorists. The answer to the question is surprisingly difficult: not only is the medium unfamiliar to communication engineers, but the mathematical details of the communication environment are complicated. In this talk, we present three examples to illustrate the current state of the field: for nanonetworking applications, we present the additive inverse Gaussian channel model; for biological applications, we discuss the information-theoretic capacity of intercellular signal transduction; and for experimental applications, we present a new low-cost, easy-to-use platform to evaluate macroscale molecular communication.

Title: An Autonomous Vehicle-Based Public Transportation System
Presented by: Dr. Albert Y.S. Lam, The University of Hong Kong
Abstract: Technology of autonomous vehicles (AVs) is getting mature and many AVs will appear on the roads in the near future. AVs become connected with the support of various vehicular communication technologies and they possess high degree of control to respond to instantaneous situations cooperatively with high efficiency and flexibility. In this talk, a new AV-based public transportation system is proposed. It manages a fleet of AVs to accommodate transportation requests, offering point-to-point services with ride sharing. We discuss the three major problems of the system: scheduling, admission control, and pricing. Scheduling is to configure the most economical schedules and routes for the AVs to satisfy the admissible requests while admission control is to determine the set of admissible requests among all requests to produce maximum profit. We develop effective methods to tackle the admission control and scheduling problems. Furthermore, we consider multi-tenancy, which can increase market competition leading to lower service charge and higher quality of service. We study the pricing issue of the multi-tenant AV public transportation system with three types of services defined. To prevent the bidders from raising their bids for higher returns, we propose a strategy-proof Vickrey-Clarke-Groves-based charging mechanism, which can maximize the social welfare, to settle the final charges for the customers. We perform extensive simulations to evaluate the performance of the proposed methods.
