Title: On the efficiency of distributed channel access method in 5G V2X networks

Speaker: Artem Otmakhov, IITP RAS, MIPT

Abstract: Applications for autonomous vehicle management that require fast and reliable data transmission are currently being actively developed. To create networks for autonomous vehicles, the 3GPP is developing 5G Vehicle-to-Everything (V2X) technology. 5G V2X networks have strict latency and reliability requirements that can be achieved through a distributed channel access method called Mode 2. One of the key features of Mode 2 is the reservation mechanism for future transmissions. At the seminar, we will discuss an efficiency of the Mode 2 for sporadic traffic. In particular, an analytical model of the Mode 2 without the resource reservation mechanism will be presented to find the probability of packet loss and network capacity. I will also show how this model can be used to find optimal transmission parameters and required channel bandwidth. Additionally, there will be an evaluation of the performance of Mode 2 with a reservation mechanism and several approaches to enhance it, which could potentially increase network capacity by up to 40% without significantly increasing the computational complexity of the algorithms implemented on the devices.

Bio: Artem has received his Bachelor’s degree in Applied Mathematics and Physics in 2024 at the Moscow Institute of Physics and Technology, where he is currently working on his Master’s degree. He is also a junior researcher at the Wireless Networks Lab, Institute for Information Transmission Problems of the Russian Academy of Sciences. His research interests include cellular networks, in particular, the study of channel access methods through mathematical modeling and simulation.
