基于AODV的自組網(wǎng)QoS路由協(xié)議
AODV-Based Routing Protocol with QoS Support

摘要: 該文在AODV協(xié)議的基礎(chǔ)上,設(shè)計(jì)了保證實(shí)時(shí)業(yè)務(wù)服務(wù)質(zhì)量的路由協(xié)議Q-AODV。該協(xié)議針對(duì)無線環(huán)境的共享媒體特性,定義了節(jié)點(diǎn)的共享頻率集,以節(jié)點(diǎn)周圍的剩余可預(yù)約帶寬作為路由度量的主要參數(shù),回避可能發(fā)生擁塞的鏈路,同時(shí)提高了網(wǎng)絡(luò)的整體效率。仿真結(jié)果表明:該算法保證了實(shí)時(shí)業(yè)務(wù)的服務(wù)質(zhì)量,在數(shù)據(jù)包的傳輸時(shí)延和網(wǎng)絡(luò)的分組遞交率方面優(yōu)于原有協(xié)議。Abstract: To guarantee quality of service of real-time traffic, an algorithm based on AODV is presented. In this algorithm, node maintains traffic information of nodes in its neighborhood. Reservable bandwidth is used as the main consult in routing.Simulation shows that the QoS of real time traffic is guaranteed and the algorithm is superior to standard AODV routing algorithm in terms of delivery rate and mean end to end packet delay.
