DETECTING A NEIGHBOR NODE LOCATION USING COOPERATIVE NEIGHBOR POSITION VERIFICATION IN VANET?

NEIGHBOR POSITION VERIFICATION

                               Efficient schemes for warning message dissemination in vehicular ad hoc networks (VANETs) use context information collected by vehicles about their neighbor nodes to guide the dissemination process. Based on this information, vehicles autonomously decide whether they are the most appropriate forwarding nodes. These schemes maximize their performance when all the vehicles advertise correct information about their positions, but position errors may drastically reduce the performance of the dissemination process. We present a proactive cooperative neighbor position verification protocol that detects nodes advertising false locations and selects optimal forwarders to mitigate the impact of adversarial users. 

DETECTING A NEIGHBOR NODE LOCATION USING COOPERATIVE NEIGHBOR POSITION VERIFICATION IN VANET

                                  Vehicular ad hoc networks (VANETs) are wireless networks that require no fixed infrastructure and are considered essential for cooperative applications among cars on the road. VANETs have many possible applications, ranging from road safety through cooperative awareness to real-time distributed traffic management. In this paper, we focus on traffic safety and efficient warning message dissemination, where the most critical goal is to reduce the latency while ensuring the accuracy of the information when a dangerous situation occurs. There, vehicles detecting abnormal situations (accident, slippery road, etc.) are deemed to notify the anomaly to nearby vehicles that could face the same problem later on.
