摘　　要：为了解决传统的TDMA协议在水下环境中存在信道资源在时间上的浪费问题,需要设计有效的MAC协议来合理分配信道资源,提高水下网络的性能。本文设计了一种能够将时隙进行动态分配的改进的TDMA协议,并在NS-3仿真平台下对其吞吐量、丢包率和端到端时延三个性能指标进行了仿真,仿真结果表明使用本文设计的协议能够提高网络的工作效率。To solve the time wastage problem of channel resources in the traditional time-division multiple access(TDMA)protocol in an underwater environment,it is necessary to design an effective medium access control(MAC)protocol to reasonably allocate channel resources and improve the performance of the underwater network.In this paper,an improved TDMA protocol is designed,which can dynamically allocate time slots.Its three performance indicators,i.e.,throughput,packet loss rate,and end-to-end delay,are simulated on the NS-3 simulation platform.The simulation results show that using the protocol designed in this study can improve the work efficiency of underwater networks.
