Abstract: As a module of NS2, the traditional movement scenario generator, when simulating routing protocol, has two limitations. One is that the transition time of stable status is long, and the other is that the uniform-distributing low bound of node speed is only zero. To remedy these faults, Tracy Camp has developed a stable movement scenario generator. The Simulation proves that simulation time can be reduced largely by using this generator. Based on this result, a simulation for AODV and DSDV routing protocol is implemented. Then the performance of two protocols is analyzed on three aspects: throughput, routing overhead packets, average delay. At last the conclusion is drawn, which shows it is essential to adopt stable movement for simulation of routing protocols.
