Abstract: VANET (Vehicular Ad hoc Network) is a kind of MANET (Mobile Ad hoc Network) in which vehicles create an ad hoc network for communication. Due to high mobility, routing in VANET is very challenging and existing routing protocols have high packet loss and delay. VANET applications require high packet delivery ratio, this problem is dealt and the routing solutions are proposed for VANET with higher packet delivery ratio compared to existing protocols. The methodology for routing adopted in GJIBR is geographic junction based routing. In additions to vehicles, junctions a special kind of node with transmitting, receiving and storing facility is added at various places which also relay the packets. Junctions are stationary and placed to improve the packet delivery ratio. The routing from vehicle to vehicle is implemented by using junctions as relays. Junctions store the packets from vehicles temporarily and decide the next vehicles to forward or relay the packet. The choice of relay decides the packet success ratio, delay and throughput. The routing solutions proposed in this research work are all about selection of relay. The relay selection must be done with criteria (i) Number of hops to destination vehicle must be less (ii) Redundant relay so that even if packet fails in one path, it can reach through another path and (iii) Relay is a must in the path to destination vehicle.
