摘要

The vehicular Ad-Hoc Networks (VANET) is constrained by high mobility of vehicles and frequent disconnections. The emerging adoption of wireless communications on surface transportation systems has generated extensive interest among researchers over the last several years. This research work deals with the crucial problems associated with routing in both city and urban environment due to false message receive from Vehicles. The main objectives of research, is to avoid the problem of false message attacks in VANET. To address this problem, the authors propose a Security Based Greedy Method (SGMA) specifically for a VANET and evaluate the performance using the NS2 simulator, which is used to add the functionality to validate message of each and every vehicle is secure and reliable. Results show that the proposed scheme will provide the score points of each vehicles, list the fake vehicles id and also SGMA operates properly in terms of packet delivery ratio. With the help of the score point received, the base station should identify the message is fake or not. The score point of vehicles is initialized in the Base station and the score point is stable or decreased depends on the feedback from receiver vehicle. The authors conclude that, the proposed work SGMA to make the network message more securable.
