An Efficient Mode Selection for Improving Resource Utilization in Sidelink V2X Cellular Networks

Abstract

Sidelink (SL) communication underlying cellular networks is a new paradigm that has been proposed to enhance the performance of cellular networks and support vehicle-to-everything (V2X) communications that enable vehicles to collaborate with other vehicles, devices, and infrastructures. In this way, vehicle-to-vehicle (V2V) communications can be performed using two communication modes, namely cellular communication based on uplink/downlink and direct V2V communications using sidelink. By properly selecting the operating mode according to the requirements of V2X services, significant operational benefits and efficient utilization of the spectrum can be achieved. In this paper, we propose a mode selection algorithm to avoid overload in the sidelink resources. A simulation-based analysis is presented to assess the performance of the proposed solution.
