                                                Vehicular Ad-hoc NETwork (VANET) 


Introduction

 One of the new networking concepts which were born during the last decade is the communication between vehicles using short range wireless solutions, known as VANET (Vehicular Ad hoc Network).Vehicle-to-vehicle and vehicle-to-infrastructure communication systems enable vehicles to share information captured by their local sensors with other interested vehicles. To ensure that this information is delivered at the right time and location, we need a proper data dissemination mechanism. The most important problem is the intermittent connectivity of VANET nodes caused by high mobility of cars. The high dynamics of cars combined with usage of short range communications make the connectivity among the cars very unstable, so even the best effort service cannot be guaranteed. The communication quality differs in cities during traffic jams (where we may obtain dense and stable networks) from one in highways (where the VANET network is sparse and the topology is highly dynamic). Due to the variety of communication scenarios it is very hard to predict the generic transport characteristics of VANETs. VANETs can greatly enhance driving safety by avoiding crashes potentially caused by emergent braking, lane changing, and so on by enabling the vehicles to communicate with their neighbours and share their driving states. In the future, it can be supposed that with all vehicles involved in VANETs they can be more responsive to the actions of their nearby neighbour nodes, resulting in fewer traffic accidents. In fact, the major design goal of VANETs is to enhance driving safety and decrease traffic accidents.

Importance of VANET in India

India is expecting a heavy increase of vehicles on the road in the near future.As per the road safety records, in India alone, there are around 400,000 road accidents with 90,000 fatal accidents are happening in a year. So we need techniques to reduce road fatalities and further improve the efficiency and ecology of road traffic. Indian roads struggle with problems of traffic flow and instability. We can save lots of lives, money, and time by forewarning appropriate information to the driver or vehicle regarding congestion and traffic management.
