【摘要】：針對(duì)移動(dòng)Ad Hoc網(wǎng)絡(luò)中按需平面距離矢量路由協(xié)議(AODV)建立路由時(shí)依賴洪泛技術(shù),在城市高速移動(dòng)的車載無(wú)線網(wǎng)絡(luò)環(huán)境鏈路易斷裂、網(wǎng)絡(luò)延遲較大等問(wèn)題,提出一種地圖坐標(biāo)輔助的改進(jìn)協(xié)議(GSAODV).GSAODV利用GPS技術(shù)獲得網(wǎng)絡(luò)中每個(gè)節(jié)點(diǎn)的坐標(biāo)位置,計(jì)算出下一跳節(jié)點(diǎn)的受限域,根據(jù)鏈路期滿時(shí)間最大原則建立到目的節(jié)點(diǎn)的可靠鏈路.通過(guò)VanetMobiSim結(jié)合NS-2實(shí)驗(yàn)表明GSAODV在封包到達(dá)率、平均端到端時(shí)延、平均路由跳數(shù)等參數(shù)均優(yōu)于AODV協(xié)議.
[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.
