DIP: Detection of invalid packets in vehicular ad-hoc networks (VANETs)

In this paper we proposed a detection of invalid packets in VANETs (DIP) scheme to classify and detect the invalid packets at the time of group communication in VANETs. The invalid packets are classified and detected using enhanced detection algorithm. This algorithm is based on the Elliptic Curve Diffie Hellman (ECDH) key agreement scheme, which reduces the processing time of invalid packets and reduce the rebatch verification time. The DIP scheme evaluated through the performance of the transmission overhead and message delay using the simulation tools. The transmission overhead and message delay are reduced and compared with the existing system. The simulation results shows that the DIP scheme is less than an existing scheme for value added services in VANETs (ABAKA).
