摘要: 为延长无线传感器网络的生存时间,提出一种优化网络生存时间的无线传感器网络地理信息机会路由协议GOROL,并根据该协议特征建立了节点剩余能量与转发能效模型.基于此模型,提出了一种自适应转发集优化算法,该机制兼顾了节点剩余能量与转发能效,能优化传输效率并最大化网络生命周期.仿真实验表明,相比能量感知机会路由CORP和GOR,GOROL具有更长的网络生存时间.

Abstract:

In order to improve the lifetime of wireless sensor networks,a geographic opportunistic routing protocol with optimized lifetime marked as GOROL is proposed,and a residual energy and forwarding efficiency model is established according to the characteristics of GOROL.Then,an adaptive forwarder-set optimization algorithm is put forward based on the model,which takes into consideration both the residual energy and the forwarding efficiency to ensure the transmission efficiency and maximize the lifetime.Simulated results show that,as compared with the energy-aware routings such as CORP and GOR,GOROL is of longer lifetime in the network.

Key words: wireless sensor networks, geographic opportunistic routing, adaptive optimization, lifetime, energy efficiency
