An optimized Algorithm for Power and Beacon Control in VANETs Based On DDPG

Abstract

The energy efficiency of in-vehicle communication terminals is critical to LTE-V2V-based in-vehicle collaborative sensing applications and other connected vehicle applications, and is the main goal of LTE-V communication system design and optimization. This paper proposed a joint optimization algorithm for power control and broadcast beacon frequency based on the LTE-V2V communication protocol. Through the simulation of different traffic flow states, the proposed algorithm is fully simulated. The results show that the method proposed in this paper can effectively deal with the dynamic randomness of the environment, and compared with several other advanced algorithms, getting higher energy efficiency.
