An efficient data dissemination scheme for emergency messages for Internet of Vehicles

Abstract

IoV is smart integration of human, vehicles, and other things around on global level like IoT but in IoV it is limited to vehicles only. Due to high mo- bility and frequent change in topology causes churn behavior which leads to network unsuitability. In case of emergency message dissemination delay in- cur due to fast topology change, network congestion and less connection life- time among vehicles. Proposed clustering based data dissemination scheme for emergency messages based on destination based clustering in which vehi- cle with similar destination grouped to gather and form cluster, then cluster head elected basis of weighted matrix using interest compatibility. Cross road communication start when vehicle receive emergency message in order to reduce delay and disseminate the accident information to other vehicles heaving same route, so other vehicles take timely action to avoid any incon- venience. Simulation results show that our proposed scheme shows better results in term of less incur during emergency message dissemination and for normal data exchange, data delivery ratio, covered area for information exchange.
