Vehicular radio connectivity in urban environment

In this paper we present a study of mobile connectivity for vehicular network in urban environment. The considered area is a real map divided into equally sized cells, each characterized by a set of information including the type of structure in the cell, cell altitude and cell attraction for vehicles. These characteristics are taken into account in two models: vehicular mobility model and electromagnetic wave propagation model. We study the impact of nodes density and obstacles present in the environment on network connectivity based on radio links. Graphs representing radio connections between vehicles are periodically generated. We examine four metrics that are nodes degree, connections duration, dominated nodes rate and cluster formation.
