Vehicular Networks Simulation

Abstract

A vehicular ad-hoc network (VANET) enables vehicles to communicate with each other directly or via roadside infrastructure in order to improve road safety and efficiency. Within a VANET, communications can potentially alter vehicular mobility and conversely, that the mobility could potentially influence vehicular communications. Therefore, a VANET simulator environment is needed that can accurately model interactions between vehicular mobility and network protocols. There are many challenges in the area of simulation of VANET. One of the most fundamental requirements of the simulation studies is that the wireless communication channel should be modelled in a very realistic way to represent the real-world environment. Also, one of the big challenges in this field is the connection of a simulation to a real-world system, e.g. using a computer-controlled motor performance test station to increase the accuracy of the microscopic road traffic simulation. This is particularly beneficial for safety applications which have to be aware of the exact mobility behaviour of vehicles. In this research we focused on building vehicular network simulator. This research surveys the challenges and the requirement for a beneficial and practical vehicular network simulator. The research aims to have a simulator that can be used in the different level of details of traffic simulation. Key words: VANETs, Simulation, Veins, SUMO, MATLAB Toolbox
