Routing Protocol Based on Multimedia Traffic in Mobile Ad Hoc Networks—Adaptive Selection and Performance Analysis

摘要:基于对多媒体业务的支持,研究了发送速率为144 kb/s的条件下移动自组网中路由协议AODV和DSR 的性能.通过对它们的性能进行比较和分析,结果表明,AODV能获得较高的报文投递率,且随移动性的变化较 小;同时,在高移动性时AODV平均的端到端时延也较小,但在低移动性时DSR能获得比AODV更小的平均端 到端时延.Abstract:In order to apply multimedia traffic in mobile ad hoc networks, the performances of AODV(ad hoc on-demand distance vector routing) and DSR(dynamical source routing) protocols at the transmission rate of 144 kb/s were investigated. Through analyzing and comparing their performances, the result indicates that a great packet delivery fraction can be obtained in AODV and its variation with mobility is small. In addition, average end-to-end delay forAODV is shorter under the high mobility, while the delay for DSR is shorter under the low mobility.
