Real Time Traffic Handling Using Ring Broadcasting in VANET

A vehicular ad hoc network (VANET) uses vehicles as mobile nodes in a Mobile ad hoc Network (MANET) to create a mobile network. Vehicles on the road usually move in one direction or in one pattern which we can use for creating network on the road. Every vehicle which is moving on the road can act as router and used to create network and with the help of this network packets can be disseminated in the VANET. Vehicular ad hoc network (VANET) provides the communication between vehicle to vehicle for providing information to travelers with new features and applications that have never previously been possible. Already ample amount of work is done for this. Routing is the important issue for which various protocols have been designed for VANETs, one of them is RBVT routing protocol. Routes are sequences of road intersections in RBVT, and for sending packets between the intersections geographical forwarding is used. This paper proposes real time traffic handling using ring broadcasting. Distributed protocols are used for unicasting packets in the network for finding the topology graph. The topology graphs show the traffic on the roads and ensure connectivity between intersections and this graph is distributed to all the available nodes in the network. Already available cellular links are used for sending the road connect ivity information. Connectivity graph is computed by centralized server and distributes it to the nodes, broadcasting is required for distributing information here ring broadcasting shall be used to improve performance and to avoid duplicity and redundancy.
