An energy-efficient routing algorithm for three-dimension underwater acoustic sensor networks

针对三维水声传感器网络,在研究水声信道能耗特性的基础上,设计了一种能量高效的路由算法Hybrid LEACH。它基于经典的LEACH算法,而在簇间传输中使用一种树状路由取代簇头与汇聚节点直接通信,减少了簇头节点的能耗,达到延长网络生存时间的目的。仿真结果显示,Hybrid LEACH算法在网络规模较大的情况下可以有效延长网络生存时间。

Considering qualities ol three -dimension underwater acoustic networks, an energy-efficientrouting algorithm is proposed after studying the energy consumption ol underwater acoustic channel. Theproposed algorithm called Hybrid LEACH is based on classical LEACH protocol. To reduce the energyconsumptionol cluster head and extend the network lifetime,a tree structure routing algorithm is appliedin inter-cluster data transmission. The experimental results show that under the circumstance of largescale network,the proposed algorithm prolongs the network lifetime effectively.
