Braking Distance Aware VANET-DSRC Protocol for Reliable Broadcasting of Life Safety Messages

Mandeep Singh Saini, Parvinder Singh, Manish Dev Sharma

Abstract


This paper proposes a protocol for reliable broadcasting of life safety messages in Vehicular Ad-hoc Networks (VANETs). In this protocol, main aim is to improve average latency for life safety message. In case of any dramatic change of speed or moving direction, the vehicle is considered abnormal and hence it transmits an emergency warning message. The proposed protocol gives the vehicle in the most dangerous situation the highest priority to transmit the life safety signal. The choice of that vehicle is done locally based on the location, direction, speed, and the breaking distance of the receiving vehicle. The superiority of the proposed protocol over existing protocols is highlighted conceptually by showing the better latency than the related protocol with simulations.
