针对节点能量有限、消耗过快易导致网络分隔的问题,提出一种改进的基于能量优化的AODV路由协议(IEO-AODV)。以AODV路由协议为基础,通过综合考虑节点剩余能量和路由跳数进行路径选择,在路由过程中,中间节点在转发路由请求时进行一个与自身剩余能量有关延迟,在目的节点进行一个延迟记录,最后根据评估函数选取最优路由。仿真结果表明,与经典AODV相比,所改进的方案能均衡网络的能量消耗,在分组投递率、延长网络的生存时间等方面有较大的优势。
Aiming at the problem that node energy is limited fast-consuming, and easily leading to network spacing, the paper puts forward an improved AODV routing protocol based on energy optimization (IEO-AOI)V).Based on the AODV routing protocol, and in consideration of the node residual energy and the number of hops to select path,intermediate nodes in the process of routing have a delay relating to their own remaining energy in the forward routing request. The destination node has a delay record, according to the selection of assessment function for optimal routing.Compared with classic AODV,simulation results show that the improved scheme can balance the network energy consumption,and has a larger advantage on packet delivery rate and network prolonged survival time.
