Connectivity of Vehicular Ad Hoc Networks with Continuous Node Distribution Patterns

The connectivity of vehicular ad hoc networks (VANets) can be affected by the special distribution patterns, usually dependent and non-uniform, of vehicles in a transportation network. In this study, we introduce a new framework for computing the connectivity in a VANet for continuous distribution patterns of communication nodes on a line in a transportation network. With this model, we obtain a new closed-form solution to the connectivity when communication nodes follow homogeneous Poisson distributions and a recursive model when communication nodes follow non-homogeneous Poisson distributions. In the same framework, we derive an approximate closed-form solution to the connectivity when distribution patterns of communication nodes are given by spatial renewal processes. With the developed models, we also discussed the impacts on connectivity of road-side stations and different distribution patterns of vehicles. Given continuous traffic conditions, the connectivity model could be helpful for designing routing protocols in VANets and implementing vehicle-infrastructure integration systems.
