摘　　要：无线网络需要所有节点都遵守媒体网络控制(MAC)层协议,以保证节点对信道的公平共享,当个别节点为了增大信道占用率而不遵守协议时,会导致网络性能降低甚至崩溃.通过对无线网络MAC层协议的分析,给出了可能的自私行为的类型与特点,分类讨论了目前无线网络MAC层自私行为检测与控制研究进展,指出了存在的问题与未来的研究方向.Wireless network needs all nodes to comply with MAC layer protocol to guarantee all nodes a fair share of channel. In order to increase their channel occupancy rate, the behavior that some nodes are not comply with the protocol will lead to the performance degradation, even cause network collapse. Based on the analysis of wireless network MAC protocol,the types and characteristics of selfish behavior were given,various typical selfish behavior detections and control algorithms in MAC layer of wireless network currently proposed were reviewed in categories, and the possible problems and research trends on selfish behavior detection and control algorithms were investigated.
