Recent years, with the rapid development of intelligent transportation systems,automotive ad hoc networks as the key technology of intelligent transportation systemsconcern has been extensively studied, and therefore the key technologies used in the theVANET car in a self-organizing network. The OMNeT++is an object-orienteddiscrete-time simulation software, and the ability to run on Windows, Linux and otheroperating systems under realistic modeling and simulation to complex traffic conditions,random traffic incidents.With the development of wireless network technology, a new type of wirelessnetwork technology-wireless Ad Hoc networks (Mobile Ad hoc Networking MANET).Network such a wireless network does not rely on any infrastructure, from theformation directly from the wireless node, each wireless node via the wireless interfaceto transfer data with the data transfer does not depend on fixed infrastructure, such asself-organization and management characteristics. Today, many routing protocols arebased mobile ad hoc network design, and some agreement can be directly applied to theorganization’s network of the VANET car since, so the VANET become MANET newtechnology in the field of intelligent transportation, has gradually become wirelessnetwork and smart very hot research topic in the transportation system.Car ad hoc network (VANET, Vehicle Ad Hoc Network) is applied to road traffic, aspecial wireless ad hoc network, aimed at achieving between vehicles (V2V Vehicle toVehicle), between vehicles and roadside nodes (V2I, Vehicle to Infrastructure) Internetcommunication can be achieved through multi-hop. On the one hand, thecommunication between the vehicle as the interaction between people, to improve roadtraffic safety and efficiency; On the other hand, the communication between vehiclesand roadside nodes designed to achieve will VANET network convenient, fast access toexisting fixed or mobile communications networks, in order to provide a richerentertainment services such as remote assistance, and in-car office, greatly improve thecomfort and convenience of the users travel.Due to a large number of nodes of vehicles in the car self-organizing network problems the VANET, systems need to be addressed is to find and maintain real-timerouting information, so this study has a high challenge. On the basis of this thesis, theanalysis of the characteristics of VANET summarizes VANET Research focuses onrouting protocols in VANET final design and implementation of proposed the VANETsimulation platform based GPCR routing algorithm.
