摘要：

Research on the effect of selfish node in wireless ad hoc networks has received considerable attention recently. However, most work concentrates on simulation study, but lacks an analytical study to accurately predict the throughput. This paper investigates the saturated and non-saturated load throughputs of IEEE 802.11 DCF (Distributed Coordinated Function) in the presence of a selfish node. Using a modified Markov model, we have derived the throughput of a node under various traffic loads in the PHY (PHYsical) layer using DSSS (Direct Sequence Spread Spectrum) and the wireless MAC (Medium Access Layer). The analytical model and throughput results have been validated by simulations.
