摘　　要：将跳频技术与Ad Hoc网络结合以提高通信系统的抗干扰能力,针对跳频扩频通信的物理特点,设计一种相适用的Ad Hoc网络的MAC协议。对已有的多信道Ad-Hoc网络接入协议进行了分析,在MMAC协议的基础上经行了改进,引入了跳频码分多址与时分双工。最后对该系统的性能进行了分析,改进后的MAC协议加强了通信的抗干扰能力和网络的各项性能。The anti-jam ability of Ad Hoc network is improved by using frequency hopping spread spectrum systems （FHSS） technology . The existing multi-channel MAC protocols of Ad Hoc network are analyzed. Based on the physical features of Frequency hopping spread spectrum, the FH-CDMA and TDD technologies are used in this protocol and their performance analyzed. The experiment results show that the anti-jam ability of communication and the network performance are enhanced by the new MAC protocol.
