Reactive Dynamic Distributed congestion control is an algorithm developed by the European Telecommunications Standards Institute as a solution to channel congestion issu in the IEEE 802.11p V2X system. In the literature, it is shown that reactive DCC algorithm produces unstable channel usage and can show poorer performance and that of non-DCC controlled system. In this report we show the impact of system synchronisation issue, that caused by the DCC based on measurements of channel-busyness ratio, and developed an asynchronous Reactive DCC mechanism that largely outperforms both the reactive DCC and non-DCC systems.
