Abstract

This paper uses two Markov chains to model IEEE 802.11p EDCA throughput over service channels. A 2-D Markov chain is constructed first to describe the backoff procedure of each access category and to infer its transmission probability. Then, a 1-D discrete Markov chain is used to describe the contention phase of an access category and to derive its collision probability. Both models consider the backoff counter freezing as well as the internal and external collisions. In addition, they both take into account the transmission opportunity (TXOP) parameter, unexploited by IEEE 802.11p, to enhance the performance of infotainment applications. Using both models, we derive an accurate model of the normalized throughput for each access category. Simulation results show that our model generates higher throughput for access categories with high priority compared to IEEE 802.11p standard.
