Abstract
Vehicular Ad Hoc Networks (VANET) supporting Vehicle-to-Vehicle (V2V) and Vehicle-to-Infrastructure (V2I) communication can increase the efficiency and safety of the road transportation systems. V2V communication uses wireless technology and in scenarios with high vehicle densities, the communication channel faces congestion, negatively impacting the reliability of the safety applications. To address this, various decentralized congestion control techniques have been proposed to effectively lower the channel load, by controlling different transmission parameters like message rate, data rate and transmission power. In this paper, we propose a novel data rate control algorithm to control the network congestion based on the Channel Busy Ratio (CBR). Simulation results demonstrate that the proposed approach outperforms existing data rate based algorithms, in terms of both packet reception and overall channel load.
