摘要：Vehicular Ad-Hoc Network or VANET is an emerging technology in the modern world .Here moving vehicles act as nodes in a network to create a dynamic network. Vehicular Ad-hoc Networks can be viewed as main component of the Intelligent Transportation Systems (ITS). Vehicular networks provide two types of communications: Vehicle –to-Vehicle, Vehicle-to-Roadside. Vehicular Ad-hoc Networks communicate based on Dedicated Short Range Communications (DSRC) which is a type of WiFi, Cellular, Satellite, and WiMAX. The Communication is based on the Wireless Access for Vehicular Environment (WAVE) dedicated to vehicle-to-vehicle and vehicle-to-roadside communications. There are specialized routing protocols for Vehicular communications such as Fisheye State Routing (FSR), Ad Hoc On Demand Distance Vector (AODV), AODV+PGB – Preferred Group Broadcasting (PGB), DSR – Dynamic Source Routing (DSR), TORA – Temporally Ordered Routing Algorithm (TORA), Greedy Perimeter Stateless Routing (GPSR), GPSR+AGF – Advanced Greedy Forwarding (AGF), PRB-DV – Position-Based Routing with Distance Vector Recovery (PBR-DV), GRANT – Greedy Routing with Abstract Neighbor Table (GRANT), Greedy Perimeter Coordinator Routing (GPCR).The future applications of Vehicular networks include maintaining safe distances between vehicles , alerting the driver of emergency vehicles , providing dynamic switching between various lanes.
