A Proposal of Autonomous Distributed Transmit Power Control in Vehicle-to-Vehicle Communication System

In ad-hoc networks such as a vehicle-to-vehicle communications (V2V) system, safety applications where vehicles broadcast the information such as car velocity, position, and so on periodically are considered. In these applications using CSMA/CA (Carrier Sense Multiple Access with Collision Avoidance), traffic congestion accompanies communication congestion which incurs a problem of decreasing communication reliability. The authors propose an autonomous distributed transmit power control method to keep high communication reliability. In this method, each vehicle controls its transmit power using feed back control based on the communication condition. The authors evaluate the effectiveness of the proposed method and the influence of multilevel modulation using computer simulation.
