First the paper introduces the characteristics of Ad Hoc network and the table-driven and on-demand routing protocols,and then mainly analyzes the two kinds of classical routing protocols and their working principles.In order to compare different performances with DSDV and OLSR,the simulation software NS 2 is used.The nodes in the simulation environment are set for high speed mode,and through the four performance indexes including the packet loss rate,average end-to-end delay,delay jitter,and throughput the performances of them cre analyzed.The simulation results indicate that OLSR relative to DSDV is more suitable for the application of high speed mobile Ad Hoc network.
