水声网络路由协议是水声网络研究的一个热点问题。水声网络路由协议面临着节点能量有限、带宽窄、高传播延迟等的限制。本文从能量和延迟角度出发,设计了一种能量平衡和延迟约束的路由协议。该协议通过感知周边节点能量和负载,使得节点在选择转发节点时尽量选择剩余能量高的节点,同时在网络负载较高时能有效避开网络拥塞区域,从而在能量均衡的同时降低数据包的端到端延迟。
Routing protocol is one of the key projects to study in underwater acoustic network. There are many challengs such as narrow bandwidth,high propagation delay and energy limit in underwater acoustic network. In this paper,we focus on energy and delay and propose a energy- balancing and delay- restricted routing protocol. In our protocol,every node is aware of the location,residual ener- gy and load of it's neighbors. When there is packet to forward,it select relay node wih higher residual energy and lower load,so it can achieve energy- balancing and lower end- to- end delay.
