A Hybrid Clustering Approach for Faster Propagation of Emergency Messages in VANET

Abstract

Road accidents can be considerably reduced by employing local warning systems across wireless vehicular communications. Vehicular Ad-hoc Networks (VANET) is one of the breakthroughs to enhance vehicle and road safety, traffic adeptness, and convenience to both drivers and passengers. Considering the high mobility model, dynamic topology changing at a rapid speed requires a real-time message propagation system that delivers a message in emergencies. The proposed approach provides reliability in terms of guaranteed delivery of messages to hidden vehicles, faster propagation of emergency messages during emergencies and reduce network load, which will further help to reduce accidents and future impact of accidents.
