IMPLEMENT MULTICASTING TECHNIQUE TO DECREASE DELAY IN VANET

ABSTRACT The vehicular Ad hoc network is the type of network in which vehicles can move from one location to another without help of any driver. To establish secure and shortest path from source to destination routing protocols are used which can be categorized into reactive, proactive and hybrid. To reduce chances of link failure, technique of root node selection is applied. When any node wants to establish path to destination, the path must be selected through root node. This reduce the chances of link failure in the network and path establishment process is made easy packet overhead is less in the proposed technique. It focuses at traffic and establishment of path by utilizing the Roptimal paths algorithm. The proposed technique is implemented in NS2 and it is been analyzed that proposed technique performs better in terms of throughput, delay and packetloss. KEYWORDS:-VANET, Multicasting technique, LAR
