Performance Evaluation of Radio Propagation Model For Vehicular Ad Hoc Networks Using VanetMobiSim and NS-2

VANET is an higher version of Mobile Ad-hoc Network (MANET).Which protocols used in the MANET are suitable to the VANET also.Many researchers are involved in VANET field, who can provide life safety and traffic management system.In continuous growth of the vehicular industry, designing and implementing VANET is a complex and wide area of research.Thus, As we all know that these studies and practices are still simulation based because it is impracticable to use real vehicles for the large scenario in different conditions to develop new algorithms and protocols for VANET.A wireless channel is unfirm and lossy so simulators for VANET require a model of these characteristics.In this paper we have highlighted the need of adequate radio propagation models for VANET with VanetMobiSim and NS2 simulators as these factors play an important role to adopt the protocol suitable for vehicle communication.
