基于水声传感器网络的多路径协同多跳通信研究

针对水声网络高误码、大时延的特点,借鉴提出了一种多路径协同多跳通信协议,该协议通过多路径、多节点的协同多跳中继通信以及冗余判决,来完成网络中端对端的远程数据传输。通过数值仿真试验分析表明:与普通的点对点直接通信和单路径多跳中继通信方式相比,此协议具有低误码、高能效的特点(距离与能量相同时,误码率低一至两数量级;限定误码率时,每比特能耗降低一个数量级),能够减少数据重发几率,提高网络的通信效率和工作寿命,特别适于水声传感器网络应用。

A multi-route cooperative multi-hop communication for underwater acoustic sensor networks

Aiming at high bit-error rate and long transmission delay of the underwater acoustic sensor network,a multi-route cooperative multi-hop communication protocol is proposed in this paper.This protocol can be used for long range end-to-end data transmission in networks by multi-route and multi-relay cooperative communication and redundant decision rule.Numerical simulation shows that the proposed protocol can achieve the lower bit-error-rate and the higher power efficiency networking performance compared with ...
