Emergency Packet Routing in Vehicular Networks for Collision Minimization in Highways

Position-Based Emergency Message Dissemination Schemes in the Internet of Vehicles: A Review

“…Moreover, the communication mode is adaptively selected depending on the vehicle's connectivity, either using V2V multi-hop data dissemination or V2I dissemination whenever a V2V connection is unavailable. Another trajectory-based scheme is proposed by Kezia et al in [107] for an emergency packet routing algorithm to avoid collision using collected trajectory data in vehicular networks in a highway scenario. A cluster head of a sphere checks the collision possibility of any of two vehicles by comparing trajectory, and a warning message is conveyed to the corresponding vehicles if a collision is predicted, employing the proactive routing protocol.…”
