Beaconless Traffic Aware Geographical Routing Protocol

Abstract

Abstract Vehicular Ad hoc Networks (VANETs) aretaking advantage of moving vehicle nodes for data communication. VANETs support many applications related to safety, infotainment and accident detection. The routing protocols are using for data communication in the presence of high mobility nodes and dynamic topologies. Due to high mobility and unpredictable topologies, the data communication becomes unreliable which causes data loss, delay and link disconnections among vehicle nodes. To address these routing limitations, various types of routing protocols have developed. In all existing routing protocols types, geographic routing protocols are one of the efficient type due to its low overhead processes. Geographical routing protocols are able to handle vehicular environment constraints. However, with many advantages geographic routing protocols are not considering many constraints of vehicular environment. Geographical routing protocols should have well defined routing metrics to deal with high mobility and other data loss and link disconnection issues. This research designs a Beaconless Traffic Aware Geographical Routing protocol by considering traffic density, distance and direction for next forwarder node and route selection. The protocol is feasible for urban dense and sparse traffic conditions and addresses delay, disconnection and packet dropping issues. Proposed protocol has simulated with state of the art routing protocols. The simulation results indicated that proposed protocol is higher performance in VANETs.
