Objectives: This paper proposes a novel method to addresses the problem of detecting and correcting collision attack in VANET and enhances the security of the nodes. Methods: The proposed Collision detection-based neighbor discovery model uses local monitoring to observe the behavior of neighborhood node. The collision detection is then shared with the immediate neighbors using warning message and propagated to a neighboring region with aiming at improving the broadcasting rate. In addition, proposed NDA-CDS uses Aloha-based Collision Correction which enables a randomized model that provides redundant information, allowing each individual node to process data packet using time slots to reduce time delay in correcting the colliding nodes which in turn maximizes the security of the nodes. The results are simulated in NS2 with each data packet size is differing from 7-49 byte. Findings: The NDA-CDC framework based on their immediate neighbors enhances the security of the nodes (i.e., vehicles) and reduces the delay time for detecting collision attack. The experimental results demonstrated that the proposed NDA-CDS model out performed than the existing state of the art works in terms broadcast rate, security and delay time for detecting and correcting collision. Improvement: The simulation result shows that proposed NDA-CDS method has advantages over the other existing system in terms of reducing the delay time for detecting collision attack and improving the security.Keywords
