车辆临时网络VANET受车辆的高移动性和频繁断开连接的限制。在过去的几年中，新兴的无线通信在地表运输系统上引起了广泛的兴趣。这项研究工作涉及由于从车辆接收的虚假信息而导致的城市和城市环境路线相关的关键问题。研究的主要目的是避免VANET中错误消息攻击的问题。为了解决这个问题，作者提出了一种基于安全性的贪婪方法SGMA专门用于VANET，并使用NS2模拟器评估性能，该方法用于添加功能以验证每辆车的安全性，可靠。结果表明，拟议的计划将提供每辆车的得分点，列出伪造的车辆ID，并且SGMA以数据包的交付比率正确运行。借助收到的分数，基站应识别消息是否假。车辆的得分点在基站初始化，得分稳定或下降取决于接收器车辆的反馈。作者得出的结论是，拟议的工作SGMA使网络消息更加可靠。
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.
