A Study on Location Verification and Routing Strategy for Vanet

VANET is a widely discussed area of wireless communication at present. VANET is a subset of MANET where nodes represent vehicles moving at high pace and vehicle traffic determined regularity. A moving vehicle can use the frequency and services to connect to other vehicles and form a Vehicular Ad Hoc Network (VANET). VANET is a wireless network composed of vehicles and roadside beacons without central access points. Although rich literature in ad hoc networks exists, the scale, availability of realistic traffic data and vehicle equipments motivate researchers to study the unique characteristics of VANET. Also, the Location verification of VANET pose new challenges for existing routing protocols. Verifying the position of vehicles is done through different techniques. Here some position identification techniques are analyzed and compared. We then examine current routing strategies designed for the vehicular networks
