Title: Collaborative Task Execution in Advanced Edge Computing Environment
Advances in edge computing will boost more smart applications including AI models, AR, video analytics, and Industrial IoT applications. In an advanced edge computing environment, edge nodes of multiple stockholders are interconnected to facilitate the share of data and computation resources, and to collaborate on joint task execution using the shared resources. A fundamental issue is how to optimize the performance of collaborative task execution in terms of various metrics. In this talk, I will first introduce the major approaches to collaborative task execution, i.e., task partitioning, task allocation and task migration. In particular, I will present our recent work on multi-user multi-resource task partitioning, which is a new challenge and was not solved before. I will also highlight our works in data aware task allocation and task migration addressing the challenges arising from collaborative edge computing. Finally, I will conclude the talk by pointing out some future directions in this topic area.

Title: Accessing From the Sky: UAV Communications for 5G and Beyond
The integration of the dramatically increasing volume of unmanned aerial vehicles (UAVs) or drones into the future 5G and beyond wireless networks calls for a paradigm shift on the design of traditional cellular systems for terrestrial-only communications. In particular, how to realize cellular-connected UAV communications and UAV-assisted terrestrial communications are both practically appealing as well as challenging, due to the high altitude and high mobility of UAVs, the unique channel characteristics of UAV-ground links, the stringent constraints imposed by the size, weight and power (SWAP) limitations of UAVs, as well as the new degree of freedom by exploiting UAV placement/trajectory and communication co-design. Substantial research efforts from both academia and industry have been devoted to advancing this exciting new field, with remarkable progress made in the past couple of years. In this talk, we will provide a comprehensive overview of the state-of-the-art results on UAV-cellular integration, with a particular emphasis placed on the latest research findings on aerial-ground interference management and trajectory optimization in UAV communications. Open challenges and promising directions for future research will be highlighted.

Title: Network Centrality as Statistical Inference in Large Networks
Massive data-sets are often generated by a large network of users. And large networks represent a fundamental medium for the spreading and diffusion of various information where the actions of certain users increase the susceptibility of other users to the same; this results in the successive spread of information from a small set of initial users to a much larger set. Examples include the spread of rumors in online social networks and power outage in smart grids. Modeling these massive data-sets as huge graphs, we introduce the idea of network centrality as statistical inference in large networks to solve two optimization problems, namely rooting out rumor sources and averting cascading failures. A network centrality with statistical basis accurately captures the optimality of the problems, and brings graph algorithm machinery to bear on solving the problems. We conclude the talk with insights on putting the theory into practice in graph analytics software development.
