【摘要】 近年来随着微电子技术、传感器技术及通信技术的发展,无线传感器网络技术得到迅猛发展。文章把节点的剩余能量考虑到贪婪路由选择算法中,提出了一种基于贪婪算法的能量有效路由策略(Greedy Forwarding Based Energy Efficient Routing Strategy,GFEER)。仿真实验结果表明该策略在保证良好的路由方向性的前提下,能够将路由的能量平均消耗到多个节点上,实现了能量负载均衡,延长了网络存活时间,特别适合应用在异构网络中。更多还原

【Abstract】 Wireless Sensor Network is a new and self-organized wireless network without complex infrastructure.With the development of microelectronics,sensor technology and telecommunication technology,wireless sensor networks develop rapidly,some successful application has been made in the military and civilian aspects.This article,the residual energy of nodes into account in the greedy routing algorithm,a greedy algorithm based on energy efficient routing strategies.The results of the simulation experiment has proved that under the premise of ensuring the good routing direction,this strategy can consume the routing energy averagely on multiple nodes,realizing energy load balance and extending the survival time of the net.Particularly suitable for applications in heterogeneous networks.更多还原
