Qualitative Based Comparison of Routing Protocols for VANET

Abstract

Vehicular ad hoc network is one of the most promising applications of MANET that an inter communication system. In VANET nodes which are vehicles can move safety with high speed and generally must communicate quickly reliably. When an accident occurs in a road or highway, alarm messages must be disseminated, instead of ad hoc routed, to inform all other vehicles. Vehicular ad hoc network architecture and cellular technology to achieve intelligent communication and improve road traffic safety and efficiency .To organize their in vehicle computing system, vehicle to vehicle ad hoc networks, hybrid architecture with special properties such as high mobility, network portioning and constrained topology .there is a lot of research about VANET for driving services, traffic information services, user communication and information services. VANET can perform effective communication by utilizing routing information. Some researchers are contributed a lots in the area of VANET. In this articles mainly focusing on significant features, performance improvement in comparisons of routing protocol for vehicular ad hoc network (VANET).
