Simulation environment realization for vehicular ad hoc network based on NS2

Abstract

In the current market, there was only specific software for network simulation or traffic simulation. They were expensive and could not support the simulation for vehicular Ad Hoc network. In order to solve the problem, simulation environment for vehicular Ad Hoc network based on free network simulation software NS2 was realized. The simulation environment was mainly realized based on the second development of NS2 software. The obstacle model and node mobile model were added. The nodes could not communicate when they were blocked by the obstacles. The nodes moved in random speed and direction on the road. Simulation results show that the simulation environment works well in the NS2 software. It is a helpful cornerstone for further research on some algorithms of vehicle Ad Hoc networks. © 2012 Springer-Verlag GmbH.
