Demand on Temporary Parallel Route Recovery for Frequent Link Failure in VANET

Abstract

Vehicular Ad-hoc Network (VANET) is an upcoming technology for communication between vehicles during the trip, which provides Internet connectivity resulting in safer roads giving access important alerts and comfort during the slip. VANET technology integrates wireless cellular and ad hoc for seamless connectivity between vehicles. VANETs are organizations that allow vehicles to communicate with each other. Wireless-vice can send data to nearby vehicles, and messages can be transported from one vehicle to another, so that the information can be broadcast throughout the metropolis. In the network, link failure is very common due to the high mobility of clients. Frequent link failure occurs as packets do not arrive at the respective goals. The mechanism proposed here establishes a form of route discovery packet parallel to the real time application to be extradited to the destination, while minimizing losses. The primary aim is to establish parallel paths during link failure scenarios for real-time applications to provide information to their destination safely. During link failures, the recovery road is parallel to the fixed temporary parallel path between the nodes. The node before the link failure packet buffers, after setting the new parallel paths before the packets stored in the buffer via the destination newly created path.
