Improving Frequent Link Failure Detection in VANET

TLDR: The main objective is to establish parallel paths during link failures scenarios for real-time applications to provide data to their destination safely, while minimizing losses.

Abstract: VANET technology integrates wireless cellular and ad hoc for seamless connectivity between vehicles. Vehicle ad-hoc networks (VANETs) are systems that allow vehicles to communicate with each other. Wireless-vice can send information to nearby vehicles, and messages can be sent from one vehicle to another, so that the information can be spread throughout the city. In the network, there is a link failure very common due to the high mobility of nodes in the network region available. So what makes frequent link failure that packets do not reach the respective destinations. The mechanism proposed here establishes a kind of route discovery packet parallel to the real time application to be delivered to the destination, while minimizing losses. The main objective is to establish parallel paths during link failures scenarios for real-time applications to provide data to their destination safely. Recovery road parallel fixed temporary parallel path between nodes when link failure. 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.
