Application-Based Congestion Control Policy for the Communication Channel in VANETs

This letter proposes a novel proactive congestion control policy for vehicular ad-hoc networks, in which each vehicle´s communication parameters are adapted based on their individual application requirements. Contrary to other approaches, where transmission resources tend to be assigned based on system-level performance metrics, the technique proposed in this paper aims to individually satisfy the target application performance of each vehicle, while globally minimising the channel load to prevent channel congestion.
