Abstract : This article presents a theoretical modeling of a small but characteristic scenario that shows a great inequity in medium access between nodes using the IEEE 802.11 DCF mode. In his configuration, two terminals evolve independently and are almost never synchronized, which results in a serious performance issue for a third emitter in between. The results are compared to simulation results and are followed by a discussion on the different performance loss causes.
