Paper Abstract

This paper investigates saturation and nonsaturation load throughputs of node based on IEEE 802.11 wireless ad hoc network protocol in presence of selfish node. To analyze the throughput of nodes, an extended two-dimension Markov model was used and a general analytical solution was derived for DCF that may be used to find throughput under various traffic loads. Meanwhile, we have done extensive simulation using Qualnet to validate our analytic results. The analytic and simulation results matched well, which revealed three interesting insights: 1) The selfish node can maximize its throughput by adopting selfish behavior. And with the increase of selfish node, the throughput of selfish node decreases. 2) With the increase of initialized contention window size of selfish node, the throughput obtained by selfish node decreases. 3) The effect taken by the selfish behavior increases with the increase of the traffic load of node. When the traffic load is saturation, the throughput that the well-behaved node can get nearly approaches to zero, which is a very undesirable results.
