Abstract: Intelligent transportation systems are rapidly spreading in all vehicles which were manufactured recently. Vehicular ad hoc networks (VANETs) are considered as a promising technology to enable communication among member vehicles (V2V) in one side and vehicles with road side unit in other side. Most applications that are supported by VANETs require a reliable connection, especially safety-based application. The major challenge in VANETs environment is the high mobility patterns which are caused by the quick and frequent topology changes. Consequently, the disconnection of the communication links is likely occurrence in VANETs, hence, a particular research attention has been focused to achieve the reliability of routing. Getting a continuous connection through a specified time between two vehicles is defined as the route reliability. This paper suggested a new vehicle acceleration and heading-based reactive routing protocol (AH-AODV) which, is enhanced by the original on-demand distance vector (AODV) routing protocol. In addition, the stability of the route is superior computed according to vehicle acceleration and heading in urban intersection. Based on the simulation results, our proposed protocol (AH-AODV) outperforms the AODV protocol significantly in packet delivery ratio and the link failure percentage metrics.
