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。 In view of the traditional AODV routing protocol using extended loop routing search algorithm leads to greater routing overhead, without considering the issue of node energy, a new algorithm is proposed. The algorithm in the routing request process based on the information obtained in the previous search, so that the extra node is in a silent state, do not participate in the next route discovery. Considering the energy of the nodes, the low-energy nodes are kept as silent as possible so as to achieve the purpose of balancing the energy usage of the nodes. The simulation results show that the improved algorithm effectively prolongs the network lifetime and improves the package delivery rate.
