Optimized Deployment of Roadside Unit in VANET for Urban Area to Reduce the Cost of Deployment

This paper concentrates over optimal deployment of Road Side Unit in a road network for communication with Vehicular Ad-Hoc Networks. Vehicular Ad-hoc networks comprises of moving vehicles communicating with each other via wifi and also some vital components like Roadside unit and On-Board Unit. Roadside Units are placed across the road for infrastructure communication. But the deployment cost of Roadside unit is very high, so, our goal is always to optimally place limited number of Roadside unit in a given region and to achieve maximum performance as well. In this paper, an algorithm is presented, the performance of the algorithm shows better results compared to other existing ones. Proposed algorithm uses selected deployment of Roadside unit and vehicle to vehicle communication in between two intersecting points of a road.
