随着移动自组网络的快速发展,对距离矢量按需路由协议(AODV)的服务质量提出了越来越高的要求。为了提升AODV在无线传感器网络通信中的表现,文章提出了一种新型的基于AODV的多度量无线路由协议(MWR-AODV)。MWR-AODV综合考虑了对路由协议性能影响重大的最小跳数、剩余能量、能量流失率和网络节点密度这四个因素,并且引入了一种低成本且高效的本地修复策略。通过Network Simulator-2仿真平台对MWR-AODV与标准AODV、DSDV协议的表现进行了仿真分析。结果表明,所提出的MWR-AODV能为无线传感器网络提供更好的通信服务,并且在均衡能量消耗延长网络寿命和平衡网络通信负载方面也有上佳表现。
With the rapid development of mobile ad-hoc networks, more and more requirements are placed on the service quality of distance vector on-demand routing protocol (AODV). In order to improve the performance of AODV in wireless sensor network communication, a novel multi-metric wireless routing protocol based on AODV (MWR-AODV) is proposed. The MWR-AODV considers four factors: minimum number of hops, residual energy, energy lost rate and network node density, which greatly affect the performance of the routing protocol, and introduces a low-cost and efficient local repair strategy. The simulation performance of MWR-AODV, standard AODV and DSDV protocol is simulated by Network Simulator-2 simulation platform. The results show that the proposed MWR-AODV can provide better communication services for wireless sensor networks and also perform well in balancing energy consumption to prolong network lifetime and balance network communication load.
