Abstract

Vehicular ad hoc network is a wireless ad hoc network which carries some important functions such as message forwarding and route determination. In areas where there is sparse density of vehicles the network gets disconnected which affects the communication between the vehicles. In the existing system position based forwarding scheme have been used in which the data will be forwarded based on its position. Initially network will be dividing into small zones. Routing will select by the nodes which are placed in the same zone. Dynamically zones will change, because of node mobility in the network. Hence it is difficult to monitor the zone nodes periodically and Over Head will be high. In this paper multicasting technique is introduced based on trajectories. Here the information will be forwarded to group of destinations. Each node estimate the delivery delay to the access point (AP) based on trajectory. Also predict the future position of the nodes. Finally the source will determine which route has less delay and then it predicts route for data forwarding. Multiple nodes are involved in network for route selection. So easily we can select better route for data forwarding in a multicast way and hence the delay is reduced.
