摘　　要：针对目前Ad Hoc网络多信道环境下MAC层存在的入侵终端问题,研究并提出了MAC层协议的改进方案。即在原有的动态信道分配MAC层协议基础上,增加了对入侵终端发生情况下信道重新分配机制和链路重新建立机制。使得AdHoc网络在入侵终端冲突发生的情况下,各节点得以迅速重新恢复通信。最后,对改进后协议的正确性和有效性进行仿真验证。The invading terminal problem in Ad Hoc network under multi-channel environment is discussed, and a new access protocol based on DCA protocol is introduced by absorbing some good ideas of other MAC protocol. The key of this protocol is the rule to reassign channels when invading terminal problem happen, This may recover communication at once. Finally, the correctness and the validity of the new channel access protocol are analyzed in systems simulation.
