摘　　要：水声通信网络(Underwater Acoustic Communication Networks,UACN)是近年来发展迅速的通信网络技术领域之一。在水声环境中,能量受限是需要解决的主要问题,而媒体接入控制(Media Access Control,MAC)是水声网络设计的关键部分,同时也是节点能量消耗的主要原因。S-MAC协议作为最具代表性的MAC层协议在节能上有着较好的表现,但S-MAC协议仍然存在一些不足。针对S-MAC协议存在的问题,论文在其基础上进行了改进,并对改进后的协议进行实验仿真。仿真实验结果表明,改进后的S-MAC协议不仅有效降低了能耗,而且在吞吐量、时延方面也有较好的表现。The underwater acoustic communication network is one of the rapidly developing communication network technolo gy fields in recent years.In the acoustic environment,the energy limitation is the main problem that needs to be solved.The media access control is a key part of the underwater acoustic network design,and it is also the main reason for node energy consumption.The S-MAC protocol as the most representative MAC layer protocol has a good performance in energy conservation,but the S-MAC protocol still has some deficiencies.For the problems existing in the S-MAC protocol,this paper improves on it and simulates the improved protocol.The simulation results show that the improved S-MAC protocol not only reduces the energy consumption,but al so has better performance in terms of throughput and delay.
