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...
This paper describes a type of selfish node behavior in the MAC layer and studies its effects on the performance of ad hoc networks. We use a game-theoretic approach to investigate the selfish behavior problem by focusing on the strategy that a node can adopt during wireless channel access. Based on this investigation, we obtained the guidelines to design a mechanism that can force the selfish node...
