On-the-Fly Segment Density (OFSD) in Adaptive Beaconing System (ABS) Based Connectivity-Aware Geocast Routing (CAGR) in VANETs

摘要

Vehicular Ad-hoc Networks (VANETs) is a Critical Communication Infrastructure (CII), a part of Intelligent Transportation System (ITS) that enable the system to minimize vehicular accident by reducing the traffic congestion. The embedment of connectivity analysis in designing of geocast routing is the in-separable phase in VANETs for fulfillment of the said objective. High mobility, link disconnection and uneven distribution of vehicular nodes makes analysis of connectivity in VANETs imperative. This paper proposes On-the-Fly Segment Density (OFSD) in Adaptive Beaconing System (ABS) based Connectivity-Aware Geocast Routing (CAGR) protocol which enhances the data delivery ratio by guaranteeing assured connectivity. Simulation result shows that the proposed scheme works better when the no of nodes is higher, as compared to greedy routing.
