Abstract

Cooperative inter-vehicular applications rely on the periodic exchange of broadcast single-hop status messages among vehicles, called beacons. The aggregated load on the wireless channel due to beacons can prevent the transmission of other types of messages, what is called channel congestion due to beaconing activity. In this paper we propose a novel statistical approach to transmit power control for beaconing congestion control, called Statistical Beaconing Congestion Control (SBCC). Unlike previous proposals, SBCC uses local information, very limited feedback and its implementation is simple. Each vehicle computes locally the power needed to comply with a given maximum beacon load as a function of estimated channel parameters, vehicle density and fading, beaconing rate. A realistic Nakagami-m and path loss propagation model is assumed. We provide a final expression of the algorithm as a linear proportional controller, with two variants, SBCC-C and SBCC-N, depending on how the parameters are estimated. Additionally, we derive an expression for the estimated communication range under interference, which approximates the average fraction of packets lost due to hidden node collisions. Finally, we evaluate the performance degradation caused by differences in local vehicle densities and propose a mechanism, called edge correction, to limit it while keeping the safety benefits of an extended range at the edge of a cluster of vehicles. SBCC is validated with a realistic hybrid network-traffic simulator and results show that it effectively controls beaconing congestion.
