水声通信网数据链路层协议仿真研究

Simulation of data link layer protocols for underwater acoustic networks

简要介绍了水声通信网的研究现状和水声网络组网方式,提出一种比较适合于浅海的水声通信网数据链路层协议,并在NS2仿真器上进行了仿真研究。仿真结果表明,该协议在浅海声信道环境中具有一定的适用性,在低负荷情况下,此协议可以满足系统的要求。满负荷时网络的吞吐量出现降低的现象需进一步改进。

Current status of underwater acoustic networks and the networking techniques are introduced. A data link layer protocol for shallow water acoustic networks is proposed and simulated on NS2. The simulation results show that the protocol is applicable to shallow water acoustic networks. For practical applications, further improvement is required to overcome the problem of throughput reduction under the condition of full network loads.
