Simulative Investigation of VANET through Small Scale LOS-NLOS Channel Conditions

VANET that stands for Vehicular Ad Hoc Network is a powerful technology to provide the communication between vehicles and nearby RSUs (roadside units). It is a type of Mobile Ad Hoc Network (MANET) to provide the drivers with following services: such as safety warnings to protect them from traffic accidents, jammed traffic information, entertainment etc. In VANETs network topology changes because mobile nodes that are vehicles here move very rapidly and cause fast change in topology. Vehicle’s nature is dynamic and highly mobile. Due to this nature, VANETs are different from other available wireless networks. Due to these characteristics there exists a no of research issues in VANET e.g. issues in routing, sharing of data, issues in security etc. In this paper, we develop appropriate scenarios for VANET in the realistic channel conditions e.g. City, RSU (Road Side Unit)-OBU (On Board Unit) scenario. We studied the performance of VANET through different small scale realistic LOS-NLOS channels conditions e.g. Rayleigh Fading Model and Rician Fading Model. We have selected NCTUns 6.0(National Chiao Tung University Network Simulator) to validate our findings that is a GUI based high-fidelity network and traffic simulator and emulator that uses the novel kernel-reentering methodology for simulation results.
