Title Efficient Geographical Routing Protocol using Beaconless approach in VANET

Author(s) Faryal Daud

Abstract Vehicular ad hoc networks (VANETs) include the vehicles to communicate with each other and share the data with the central repositories. The intelligent transportation systems timely manage the traffic hazards and inform the nearby vehicles to ensure road safety. It is quite important to select the next relay node in VANET who can transmit the messages to next vehicles. For communication between vehicles, it is very important to select more accurate vehicles as next forwarder to avoid loops and increase the cost of the network. During the next forwarder node selection. It considers the long distance and large angle to choose the farthest node. The main problem is that it does not consider all possible realistic scenarios like the node at largest distance with greater angle. Also, it was not defining the case if those vehicles which have smaller distance to source node along the small angle with destination node. In this research, these parameters are defined and calculate their values by considering different scenarios. In proposed scenario, the network can achieve high throughput and packet delivery ratio, and reduce the delay in the network. The proposed protocol for vehicular network calculates the distance between node, angle of the nodes and traffic density of the road on the intersection point and set its priority according to the condition. The NS2 simulator is used to evaluate the performance of the proposed protocol. The proposed protocol achieved the better throughput, packet delivery ratio and reduce the delay as compared to BTA-GRP, IPN and IB.
