Improving the Reliability and Availability of Vehicular Communications Using Voronoi Diagram-Based Placement of Road Side Units

Abstract

Vehicular Ad-hoc Networks (VANETs) form the basis for critical services that improve traffic safety and alleviate traffic congestion. The reliability of VANET-based services and applications that are based solely on vehicle-to-vehicle (V2V) communications, however, is hindered due primarily to limited and often fluctuating V2V communications. To address this limitation, Road-Side Units (RSU) have been proposed to complement V2V communications by providing stable event and data brokering capability. Effective placement of the RSUs is a key requirement in improving reliability of VANET services. This poster describes a novel Voronoi network-based algorithm for the effective placement of RSUs. The reliability metric considered in placing the RSUs involves bounding both the delay incurred by communication packets and packet loss, which in turn ensure timeliness and correct operation of the VANET services.
