一种基于TDMA的水声传感器网络MAC协议

A TDMA-Based MAC Protocol for Underwater Acoustic Sensor Network

由于水声信道的传播时延很高,传统的TDMA协议存在时隙过长导致吞吐量下降的问题。本文提出一种基于TDMA的改进型MAC协议,该协议允许发送节点在一个时隙内发送多个数据包或在时隙中间时刻发送数据包,改善长时隙对TDMA协议性能的影响。仿真结果表明该协议可以有效提高时隙的利用率并提升网络吞吐量。

Due to the high propagation delay of the underwater acoustic channel, the traditional TDMA proto-col has the problem of throughput degradation due to long time slots. This paper proposes an improved MAC protocol based on TDMA, which allows sending nodes to send multiple packets in one time slot or send packets at intermediate time slots. This mechanism improves the impact of long time slots on the performance of the TDMA protocol. Simulation results show that the protocol can effectively improve the utilization of time slots and improve network throughput.
