Ad Hoc High-Dynamic Routing Protocol Simulation and Research

Ad Hoc network is a kind of wireless mobile self-organized network without fixed facilities. The structure of topology in dynamic changes has considerable effect on the performances of routing protocol agreement. This paper studies three traditional routing protocols, which are DSR, AODV, and OLSR. We use OPNET software as simulation tool. In order to design airborne platform network topology structure on the background of high-dynamic simulated scheme with Random Constant Speed Mobile Model (RCS), which makes the simulation scenario is more close to the high-dynamic mobile node dynamic performance. We also analyze their performance by comparing the parameters such as network delay, normalized network throughput, route load, and delivery ratio. The result of the simulation shows that the comprehensive performances of the OLSR agreement transcend others. And it is more suitable for ad hoc network whose node moves fast and the structure of the network topology changes frequently, which provide a basis for further research.
