A Multi-Channel Choose Policy Base on Conflict Estimating in Wireless Vehicular Networks
Ding-xin Zhao, Xianzhong Xie · ASME Press eBooks · 2011
This paper proposes a Markov chain model and a continuous idle slots model for the transmission mechanism of 802. 11p/1609.Through the two models, the conflict probability is estimated in every server channels. Based on the conflict probabilities, a channel choose policy is given to improve the average throughput of WAVE. The simulation results show that the average throughput rate improved obviously.
