Hybrid Routing Approach Depending on Different Message Types in VANET

Abstract

VANET is a technology that uses moving cars as nodes in a network to create mobile network. VANET is part of mobile ad-hoc network that facilitates communication between group of vehicles to provide driver safety, traffic updates, entertainment, data sharing etc. Some of the promises of VANET are intelligent traffic system, early warning signals for vehicles that could minimize road mishaps and provision of better in-transit communication. As the performance of communication depends on the selection of best route while communication & routing of data is done by routing protocols. To provide smart communication, it is must to make an analysis of routing protocols in VANET. It is assumed that every vehicle has the digital map of streets comprised junctions and streets segments. In this paper, cluster head and cluster members communicate with each other effectively. Cluster members generate messages as per their need. The cluster head gathers in formations from its neighboring cluster members.
