摘要
针对无线传感器网络寿命最大化问题,基于无线传感器节点能耗分布特点和数据传输能耗模型,建立无线传感器网络生存周期的数学优化模型,并针对最小能耗路由的能耗不均衡问题和能量均衡路由的能耗开销问题,综合考虑网络中节点的剩余能量和节点间发送数据的能耗,提出一个适合无线多跳传感器网络的自适应路由算法。仿真结果表明,提出的路由算法能充分地利用有限的能量资源,较大地延长网络生存周期。
Aiming at the problem of maximizing lifetime of wireless sensor networks,proposes a mathematical optimization model of network lifetime,which is based on the characteristics of sensor node＇s energy and data transmitting model,for the wireless sensor networks.Due to the problem of energy consuming among all nodes under adopting minimum energy routing algorithms,and the problem of consuming much energy while energy-balanced routing algorithms are used,proposes an adaptive routing algorithm,in which both remaining energy of nodes and energy consumption for delivering packets on wireless links are considered.Simulation result shows that the proposed routing algorithm can utilize the limited energy resources rationally,and prolong the network lifetime.
