摘要
针对传统的AODV路由协议采用扩展环路由搜索算法导致的路由开销较大,没有考虑节点能量的问题,提出一种新的算法。此算法在路由请求过程中能够根据以前搜索中得到的信息,让多余的节点处于静默状态,不参与下一次的路由发现。并且综合考虑节点能量,尽可能地让低能量节点处于静默状态,从而达到均衡节点能量使用的目的。仿真结果表明改进算法有效延长了网络生存时间,提高了包投递率。
Aiming at the heavy routing overhead and the uneven energy of every node brought by traditional AODV routing protocols in using the expanding ring route search algorithm, a new algorithm is proposed. This algorithm, in accordance with the information obtained in the previous search, makes the redundant nodes in a quiescent state and not participate in the next route search in the process of routing request. Meanwhile, the energy of nodes is comprehensively considered so trying best to let the nodes with low energy in a quiescent state. Simulation results show that the proposed algorithm could effectively extend the network lifetime and improve the packet delivery ratio.
