摘要
基于对多媒体业务的支持,研究了发送速率为144kb/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.
In order to apply multimedia traffic in mobile ad hoc networks, the performances of AODV(ad hoc ondemand 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 endtoend delay for AODV is shorter under the high mobility, while the delay for DSR is shorter under the low mobility.
