水声传感器网络簇头分层通信模式路由算法

摘要

Routing protocol plays a very important role in underwater acoustic sensor networks. Based on the traditional TEEN protocol, a new routing protocol named HCM-TEEN(Hierarchical Cluster-communication Model on TEEN) has been put forward. The improved algorithm sets a new threshold function on the basis of the process of cluster candidate and the cluster elimination, and then introduces a Hierarchical Cluster-communication model in the period of data transmission to optimize the routing process. The experiment by the Matlab proved that HCM-TEEN performed better than the traditional algorithm on the network lifetime and the network average residual energy.%路由协议在水声传感器网络研究领域中扮演着非常重要的角色。基于传统的TEEN协议路由算法，提出了水声传感器网络中簇头分层通信模式的路由算法(HCM-TEEN)。新算法从簇头候选与淘汰过程入手，设置新的阈值函数。在簇头确定完成后，在数据传输阶段引入簇头分层通信模式，从距离和能量的角度上优化路由选择。通过Matlab仿真实验显示， HCM-TEEN算法与传统的算法相比在网络生命周期和节点平均剩余能量上都更具优越性。
