摘　　要：部署在水下的传感器节点可以将数据及时传送到陆地,来实现精确的、实时的、时间空间连续的水下监视。为了实现部署在水下的节点与陆地实现稳定通信,需要解决一系列问题。针对水下传感器网络的特性,首先阐述了以接收者为中心的RC-MAC协议的原理以及基本思想,并在网络仿真平台上针对水声环境特殊性搭建了水下仿真场景,对RCMAC协议进行模拟仿真,分析比较在各种不同水声场景中RC-MAC协议的吞吐量、能量消耗等数据。通过仿真实验发现,RC-MAC协议在水下节点数量比较少、节点分布范围比较广时信道的吞吐量更高,节点分布较浅、数量小于4时节点节能效果较好。Deployed underwater sensor nodes can be promptly transferred the data to the land, to achieve accurate, real-time, continuous space and time underwater surveillance. In order to implement the stable communication between nodes deployed underwater and land, need to solve a series of problems. According to the characteristics of underwater sensor networks, describe the principle and basic idea of RC-MAC protocol with the receiver as the center,and the underwater simulation scene is built on the network simulation platform for the specialty of underwater environment. Simulate RC-MAC protocol, analyze and compare the throughput and energy consumption of RC- MAC protocol in diverse underwater scene. The results show that the throughput of the channel is better when the RC-MAC protocol has small number of nodes with relatively broad distribution, when the nodes distribution is shallow, the number of nodes is less than 4, saving better.
