能量高效的水声传感器网络路由协议

为了解决水下声信道对网络性能的影响,在综合考虑了节点的剩余能量和信道传输质量的基础上,提出了一个基于链路质量估计的能量高效路由协议。该协议根据节点的可用能量、位置以及信道传输质量估计等因素确定转发节点,能减少信息的盲目转发,提高能量的利用率,均衡网络的能量消耗,从而实现了网络能量的平稳下降,有效地延长网络的生存时间。仿真结果表明,该协议具有能量利用率高,信道利用合理等特点,比无信道传输质量估计的协议能量利用率提高9%左右。

Energy-Efficient Routing Protocol for Underwater Acoustic Sensor Networks

To deal with the effect of network performance caused by underwater acoustic channel,an energy-efficient protocol based on estimating quality of link is proposed considering both node＇s residual energy and link quality.The protocol chooses forwarding nodes by node＇s residual energy,position and transmission quality of link,decreases forwarding-unnecessarily packets,raises energy utilization rate,balances network energy consumption,and achieves goals of balanced energy consumption,effectively prolongs network time of life.Simulation results show that the proposed protocol has good energy utilization rate,utilizes acoustic channel reasonably,and raises energy efficiency by 9% than without link quality estimation.
