Abstract

This paper provides an analysis of optimum offered load that maximizes the throughput of IEEE 802.11 media access control (MAC) protocol for the multihop network. We extend Ping Chung Ng analysis in presence of hidden terminal and capture effect, with some modifications in the derivation of throughput. The analytical throughput results are validated against ns-2 simulation using direct sequence spread spectrum (DSSS) MAC layer. This approach analyses whether the resulting performance of the network is hidden node limited or spatial reuse limited. In this paper, we provide a throughput analysis of the IEEE 802.11 based multihop network for various distances between the two successive nodes.
