The Global Positioning System (GPS) is a space-based global navigation satellite system (GNSS) that provides reliable location and time information in all weather and at all times and anywhere on or near the Earth when and where there is an unobstructed line of sight to four or more GPS satellites. The Global Positioning System (GPS) is actually a constellation of 27 Earth-orbiting satellites (24 in operation and three extras in case one fails). In VANET, this location information is shared with the Roadside Units and the vehicles to determine accident affected vehicle and to send alert packets to these vehicles. Generally, in VANET, broadcasting scenario can be seen, which is not required as all the vehicles in the network are not affected when emergency event occurs. Instead, multicasting of alert packets is more useful. Therefore, in this paper proposed system is used to design and develop vehicle node having travelling direction and the location information. This node will work as a road side unit and it will manage all vehicles location information and also manage detection of failure node in the network. Once the failure node is detected it will calculate the relative position of other vehicle and multicast the messages to particular vehicle.
