英文摘要	浅海水声信道的快衰落、长延时使水声网络媒介访问控制(MAC)层协议的性能受到了较大的负面影响。为了能更好地将无线传感器网络的MAC协议适用于水声网络,本文着重对AlOHA协议和冲突避免多址接入(MACA)协议进行改进分析,借助通信网络仿真工具OPnET,比较两者在吞吐量、时延、能量损耗和分组丢失率4方面的性能结果。仿真结果表明:与AlOHA协议相比,MACA协议能更好地提高性能,有利于在水声网络中使用。; The fast fading and long time delay in the shallow water acoustic channels bring in a lager negative influence to performances of medium access control(MAC) layer protocol for underwater acoustic networks.In order to better apply MAC protocol used in the wireless sensor network to underwater acoustic networks,this paper focused on the analysis of Aloha protocol and multiple access collision avoidance(MACA) protocol and simulated them respectively through OPNET under the circumstances of wireless networks and underwater acoustic networks.Then performances such as throughput,delay,energy consumption and packet loss ratio were compared.Simulation results shows compared to Aloha protocol,MACA protocol can improve performances preferably and be used effectively in underwater acoustic networks.
