Özet

In this paper, an analytical model is developed to investigate the performance of the IEEE 802.11 Distributed Coordination Function (DCF) for different contention window in vehicular ad hoc networks (VANETs). The relationship between performance metrics and contention window size is derived by analytical analysis based on two-dimensional (2D) Markov chain model. The channel busy probability, successful transmission probability, collision probability, throughput and packet dropping rate (PDR) are obtained. The simulation result is also demonstrated to understand the performance of IEEE 802.11 DCF in VANETs for different contention window.
