Abstract

Applications for VANETs will require seamless communication between vehicle-to-infrastructure and vehicle-to-vehicle. However, this is challenging because this is a highly mobile environment. Therefore, traditional handover techniques are inadequate due to the high velocity of the vehicle and the small coverage radius of Road-side Units. Hence in order to have seamless communication for these applications, a proactive approach needs to be carefully investigated. This requires measurements from a real testbed in order to enhance our understanding of the communication dynamics. This paper is about building and evaluating a prototype VANET network on the Middlesex University Hendon Campus, London to explore these issues. The testbed is being used to investigate better propagation models, road-critical safety applications as well as algorithms for traffic management. In addition, the Network Dwell Time of vehicles travelling in the coverage of the RSUs is measured to explore proactive handover and resource allocation mechanisms.
