Joint Resource Allocation and Power Control for V2V Communication of High-density Vehicle Network

Device-to-device (D2D) communication has been considered as a possible enabler for vehicle-to-vehicle (V2V) applications, which induces the intra-cell interference inevitably. To ensure road safety and traffic efficiency, V2V has stricter requirements of latency, reliability, and access availability. In this paper, we propose a resource allocation method in a high-density vehicle network to maximize the number of reliable vehicular links. Firstly, we analyze and mathematically model the actual requirements for vehicular communications and traditional cellular links, and propose a problem formulation to fulfill these requirements. Secondly, we propose the serial and the clustering resource allocation algorithm to solve the resource allocation problem. The simulation results are presented to illustrate that the proposed schemes can provide reliable communication and improve the number of vehicles successfully established communication.
