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.
