COMPARATIVE ANALYSIS OF VEHICULAR ROUTING PROTOCOL IN VANET FOR SMART CITY SCENARIO

Vehicular ad hoc network (VANET) is an ongoing new technology similar as ad hoc network, wireless network and cellular technology to achieve inter-vehicle communications and vehicle to infrastructure communication and improve road traffic safety and efficiency. VANETs are different from other kinds of ad hoc networks by their hybrid network architectures, vehicle node movement characteristics, and new application scenarios for safety purpose. Therefore, VANETs is a unique networking research challenges, and the design of an efficient routing protocol for VANETs is very crucial. In this article, we discuss the research challenge of different routing protocol in VANETs and compared all routing protocols and distinguish efficient routing protocol for VANETs. Vehicular ad-hoc networks have recently attracted great interest in the research community, and reliable data transmission and network connectivity has become an important issue.
