【摘要】：针对移动Ad Hoc网络中按需平面距离矢量路由协议(AODV)建立路由时依赖洪泛技术,在城市高速移动的车载无线网络环境链路易断裂、网络延迟较大等问题,提出一种地图坐标辅助的改进协议(GSAODV).GSAODV利用GPS技术获得网络中每个节点的坐标位置,计算出下一跳节点的受限域,根据链路期满时间最大原则建立到目的节点的可靠链路.通过VanetMobiSim结合NS-2实验表明GSAODV在封包到达率、平均端到端时延、平均路由跳数等参数均优于AODV协议.
[Abstract]:In order to solve the problems of on-demand plane distance vector routing protocol (AODV) in mobile Ad Hoc network, which relies on flooding technology, the link of vehicle wireless network with high speed mobile in city is easy to break and the network delay is large, an improved map coordinate aided protocol (GSAODV). GSAODV uses GPS technology to obtain the coordinate position of each node in the network, and calculates the finite domain of the next hop node. According to the principle of maximum link expiration time, a reliable link to the destination node is established. VanetMobiSim combined with NS-2 experiments show that GSAODV is superior to AODV protocol in packet arrival rate, average end-to-end delay, average routing hops and so on.
