中文摘要：
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。
英文摘要：
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 the directly point-to-point and single-route multi-hop communication protocols. Because the proposed protocol decreases the probability of data retransmission and improves the communication efficiency and working-life of networks, it is appropriate for the underwater acoustic sensor networks.
