摘要/Abstract

摘要： 水声通信网络由于可以弥补传统海洋探测技术的不足，在海洋信息采集、环境监测、灾难预
报、辅助导航、水声反潜等民用、军事领域有诸多重要应用.因此，组网技术也成为近年来水声通信领域
的研究热点之一其中数据链路层的媒质控制协议关系到信道资源的有效分配及网络性能.结合能量及
网络吞吐量效率因素，木文设计了一种用于分布式远距离多跳水声通信网络的媒质控制协议协议.己有
的的新性能的水声调制解调器并没有开发相应的低功耗网络媒质控制协议.有人提出了一类分布式能
量有效的竞争媒质控制协议，称为Tone-Lohi ( T-Lohi)协议，该协议采用了信道预约机制，共有三个类
型:时间同步的T-Lohi协议、保守非时间同步T-Lohi协议及主动非时间同步T-Lohi协议.木文在分析
该类协议的基础上讨论了分布式多跳水声通信网络的竞争型媒质控制协议.设计了多跳式的T-Lohi协
议，通过采用动态竞争回合、优先权及新的竞争者计数方式等策略，将T-Lohi协议从单跳方式扩展为多
跳方式，该协议不需要时间同步.为了充分结合原协议的优点，平衡网络信道利用效率和数据包丢失概
率，木文还对竞争回合周期进行了改进.在OPNET仿真平台下对该协议的网络吞吐量性能、丢报率和
公平性进行了仿真，验证了所设计协议的有效性.

Abstract: Underwater Acoustic Network(UAN)technology has become attractive to the researchers in the field of
underwater acoustic communication in recent years^[1-4].One of the key technologies is the design of media access
controlmulti-hop and long range acoustic sensor networks. A multi-hop T-Lohi protocol(MT-Lohi) is designed，which ex-
tends the T-Lohi protocol from singl}hop networks to multi-hop networks by introducing dynamic contention
round，pseudo tone，priority-based contention, new contenders counting mechanism, In order to gain a balance
between good channel utilization and low probability of packet loss,thc length of the duration of contention round is
modified also. Simulation under OPNET platform is carried out to evaluate the performance in throughput，packet
loss rate and fairness,and to verify the effectiveness of dynamic contention round.
