IoT Thrust Seminar - Towards the 6GB IoT: Joint Designs of Communication, Computing and Caching for Fog-Radio Access Network
With the upsurge of IoT applications, fog-radio access network (FRAN), which features fog computing, or mobile edge computing (MEC), has emerged as a promising solution to satisfy the growing demand for low-latency and computation-intensive services in the 6GB mobile networks by harnessing the synergy between the cloud and the edge. In this talk, we focus on pursuing secure, sustainable, scalable and smart (4S) IoT in three use cases, with emphasis on the integrated design of communication, computing and caching (3C) for FRAN. We first propose a (robust) self-sustainable harvest-and-jam protocol, which enables cooperative jamming against eavesdroppers by wireless power transfer, thus improving on the secrecy transmission in a multi-antenna amplify-and-forward (AF) relay wiretap channel. Then, we introduce a D2D-enabled cooperative MEC system, where a local user solicits its nearby wireless devices for low-latency computation by joint task assignment and resource allocation. Furthermore, motivated by scenarios where parameter server (PS) based distributed learning is unavailable or undesirable, federated learning (FL) over wireless D2D networks is discussed, for which we provide theoretical insights into the performance of both wireless digital and analog implementations. Finally, some future directions of research are proposed identifying ethical aspects of future mobile network innovation.
