Abstract
The Wireless Access in Vehicular Environ-ments (WAVE) system is developed for enhancing the driving safety and comfort of automotive users. However, owing to the nature of contention based channel access scheme, the WAVE system suffers from Quality of Service (QoS) degradation for safety applications caused by the channel congestion in scenarios with high vehicle. In this paper we study the performance of the Emergency Elec-tronic Brake Light with Forwarding (EEBL-F) application as an example of the safety application in congested sce-narios, and propose a congestion control architecture for Vehicular Ad-Hoc Networks (VANET). Concentrated on Medium Access Control (MAC) layer, two concrete con-gestion control approaches through manipulating MAC transmission queues are introduced. The effectiveness of the proposed congestion control approaches is evaluated through stochastic simulations. Besides, the impact of adaptive transmit power level on congestion control in VANET is also discussed with simulation results.
