Intelligent Vehicular Ad-Hoc Network

Abstract

This project is about an emerging and exciting ad hoc network application in which vehicles act as nodes. This area has some promised aspects and activities that will be offered, which are largely related to safety, convenience, entertainment and various other topics of interest. It is an ad hoc vehicle network, known as the "ad hoc vehicle network (VANET)". The ad hoc vehicle network is a form of ad hoc mobile networks, to provide communication between nearby vehicles and between nearby fixed vehicles and equipment, i.e. road equipment. Wireless communications between vehicles enable safety applications, such as accident avoidance, and non-safety applications such as traffic congestion warnings with the intention of improving safety in driving conditions. Since test stand environments with limited costs limit prototype testing, VANET researchers often turn to simulation toolkits from which a rich set of environmental scenarios is modeled. However, despite the availability of such tools, the results are inconsistent. While VANET researchers often model the loss of propagation deterministically based on the distance of the transmitter receiver, the fading and shading effects are often stochastically modeled, which leads to environmentally independent probabilistic results. real and, therefore, do not consider realistic road topologies and the presence of obstacles. In this paper, we implement the obstacle shading model empirically validated for MATLAB using Open Street Map (OSM) construction data to determine deterministically the effects of line of sight propagation using computational geometry techniques, and expand further the results to evaluate safety performance assessments.
