报告题目：Toward Reliable and Scalable Vehicle-to- Everything (V2X)
报告人简介：Lin Cai is a Professor with the Department of Electrical & Computer Engineering at the University of Victoria. She is an NSERC E.W.R. Steacie Memorial Fellow, an Engineering Institute of Canada (EIC) Fellow, and an IEEE Fellow. In 2020, she was elected as a Member of the Royal Society of Canada's College of New Scholars, Artists and Scientists, and a 2020 "Star in Computer Networking and Communications" by N2Women. Her research interests span several areas in communications and networking, focusing on network protocol and architecture design supporting emerging multimedia traffic and the Internet of Things. She was a recipient of the NSERC Discovery Accelerator Supplement (DAS) Grants in 2010 and 2015, respectively. She has co-founded and chaired the IEEE Victoria Section Vehicular Technology and Communications Joint Societies Chapter. She is an elected member of the IEEE Vehicular Technology Society (VTS) Board of Governors, 2019 - 2024. She is the Associate Editor-in-Chief for IEEE Transactions on Vehicular Technology and has served as the Distinguished Lecturer of the IEEE VTS Society and IEEE ComSoc Society.
摘 要：Reliable and scalable wireless transmissions for Vehicle-to-Everything (V2X) are technically challenging. Each vehicle, from driver-assisted to automated one, will generate a flood of information, up to thousands of times of that by a person. Vehicle density may change drastically over time and location. Emergency messages and real-time cooperative control messages have stringent delay constraints, while infotainment applications may tolerate a certain degree of latency. On a congested road, vehicles need to exchange information badly, only to find that services are not available due to scarcity of wireless spectrum. Considering the service requirements of heterogeneous V2X applications, service guarantee relies on an in-depth understanding of network performance and innovations in wireless resource management. In this talk, we compare the performance of vehicle-to-vehicle (V2V) beacon broadcasting using random access-based (IEEE 802.11p) and resource allocation-based (C-V2X) protocols and introduce several enhancement strategies to mitigate packet collisions, recover from transmission errors, and support two-user non-orthogonal transmissions.
