Title: Momentum-Based Resource Control and Optimization at the Edge of IoT
Abstract: Due to the proliferation of smart mobile devices and Internet-of-Things (IoT), recent years have witnessed an explosive growth of mobile data demands. As a result, today’s centralized cloud-based network infrastructures are being stretched to their capacity limits. The quest for an ever-increasing network capacity has attracted tremendous research interests to push the work load to the network edge. Moreover, the emerging IoT applications introduce stringent performance requirements on throughput, latency, and convergence speed, all of which call for new control and optimization algorithmic techniques in edge computing. To this end, in this talk, we introduce a new momentum-based network congestion control and scheduling optimization approach to address the above challenges at the IoT edge. Based on this momentum-based approach, we develop a cross-layer optimization framework that offers throughput-optimality, fast-convergence, and significant delay reduction. This framework opens the door to an unexplored network congestion control and scheduling optimization paradigm that leverages advanced techniques based on “memory/momentum” information for data-intensive IoT edge computing. Besides the momentum-based approach, I will also talk about some of my ongoing and future research directions.
