A Vehicular Ad-Hoc Network or VANET is a sub form of Mobile Ad-Hoc Network or MANET that provides communication between vehicles and between vehicles and road-side base stations with an aim of providing efficient and safe transportation. A vehicle in VANET is considered to be an intelligent mobile node capable of communicating with its neighbours and other vehicles in the network. VANET introduces more challenges aspects as compare to MANET because of high mobility of nodes and fast topology changes in VANET. Various routing protocols have been designed and presented by researchers after considering the major challenges involved in VANETs This paper provides a survey of routing protocols for VANET . It covers application areas, challenges and security issues prevailing in VANETs. Vehicular Ad Hoc Networks (VANETs) is technology that integrates the capabilities of new generation wireless networks to vehicles. VANET builds a robust Ad-Hoc network between mobile vehicles and roadside units. It is a form of MANET that establishes communication among nearby vehicles and adjacent fixed apparatus, usually described as roadside apparatus. VANET can achieve affective communication between moving node by using different ad-hoc networking tools such as Wifi IEEE 802.11 b/g, WiMAX IEEE 802.10, Bluetooth, IRA. VANET inculcate sufficient potential in vehicles to transmit warnings about environmental hazards, traffic and road conditions and regional information to other vehicles. The major intend of VANETs is to absolute the user’s choice on the road and build their drive safe and snug. Vehicles move at such a high speed that it is harder to maintain a seamless handoff and a steady connectivity to the Internet.
