Abstract: We propose a novel medium access control (MAC) protocol for machine-type communications in the industrial internet of things. The considered use case features a limited geographical area and a massive number of devices with sporadic data traffic and different priority types. We target at supporting the devices while satisfying their quality of service (QoS) requirements with a single access point and a single channel, which necessitates a customized design that can push the MAC performance towards the boundary. The proposed MAC protocol comprises a new slot structure, corresponding channel access procedure, and mechanisms for supporting high device density and providing differentiated QoS. A key idea behind this protocol is sensing-based distributed coordination for significantly improving channel utilization. To characterize the proposed protocol, we analyze its delay performance based on the packet arrival rates of devices.
Bio: Dr. Jie Gao received his M.Sc. and Ph.D. degrees in electrical engineering from the University of Alberta, Canada, in 2009 and 2014, respectively. He joined the Department of Electrical and Computer Engineering, Marquette University, Milwaukee, United States, as an assistant professor in August 2020. Before that, he was a research associate with the University of Waterloo (2019-2020) and a postdoc with Ryerson University (2017 – 2019). His research interests include could and mobile edge computing, machine learning for communications and networking, and the Internet of things (IoT) and industrial IoT.
