摘要:

按需路由协议AODV中仅以最小跳数作为路由选择依据,导致网络资源分配不均及网络寿命减少。提出了AODV-HE算法,该算法优化路由选择机制,综合最小跳数和节点剩余能量提出一种反向路由判据权值,并根据此权值选择最佳路由。仿真结果表明,该算法能有效提升分组投递率,降低端到端时延,改善网络资源分配问题并有效延长网络寿命。

关键词: 路由选择机制, 最佳路由, 资源分配, 网络寿命

Abstract:

AODV routing protocol takes the minimum hop as the only basis in route selection,causing the uneven allocation of resources and reduction in network lifetime.A routing algorithm based on minimum hops and energy of node(AODV-HE)was proposed.By integrating both minimum hop and residual energy of each node,the algorithm optimized the routing mechanism and presented a selection weight of reverse routing,based on which the best route was chosen.Simulation results show that the algorithm can effectively increase packet delivery ratio and reduce the end-end delay,and it can also improve the allocation of network resources and extend network lifetime.

Key words: routing mechanism, best route, allocation of resources, network lifetime
