Emergency Broadcast in VANET by Considering Human Satisfaction

Abstract

The emergency broadcast is an important service in Vehicular Ad Hoc Network (VANET) for the safety of vehicle drivers. The design of a broadcast scheme in a city environment becomes challenging. In this paper, we extend our previous work of using the concept of water wave propagation by further con-sidering human satisfaction. As long as the drivers have sufficient time to react to an emergency event, a lazy rebroadcast approach is applied to significantly reduce rebroadcast times and network traffic.
