Abstract

In this paper, the performance of IEEE 802.11-based single hop broadcast network assuming saturated nodes is studied by determining the threshold parameters for both saturation throughput as well as delay. An upper limit for the achievable throughput is derived by maximizing the broadcast saturation throughput. An analytical expression for optimal contention window size required to meet the desired objective is derived. Expression for the maximum saturation throughput is also obtained. The results reveal that the maximum saturation throughput is independent of the number of contending stations. This work also addresses the computation of the minimum delay in a wireless ad-hoc network with saturated nodes. The optimal contention window that minimizes the saturation delay under broadcast is also determined. The minimum delay parameter is significant in such a network since the network applications are generally not delay tolerant.
