Modeling Connectivity of Inter-Vehicle Communication Systems with Road-Side Stations

In this letter, the authors discuss the improvement that roadside stations can bring to the multihop connectivity of intervehicle communication (IVC) in a traffic stream. With a recursive model of connectivity, they study impacts of different densities of roadside stations and different positions of roadside stations for uniform or non-uniform traffic streams. The rest of the article includes the introduction of an analytical model of an IVC system with roadside stations, the analysis of the connectivity of an IVC system under different conditions, and a summary and discussion of the findings. From the numerical studies, they find that, as expected, roadside stations can help relay information in an IVC system and have the following impacts on the performance of an IVC system: the larger the density of roadside stations, the more improvement in the connectivity; different locations of roadside stations relative to a traffic stream can yield different levels of improvement in connectivity; and it is better to deploy roadside stations along less congested traffic. This is consistent with the observation that sparse traffic is the communication bottleneck of an IVC system. For a particular road network, the best locations of roadside stations can be calculated with the proposed model. In addition to considerations in performance, economic constraints should also be considered when deploying roadside stations, since available budget would limit the number of roadside stations and may yield sub-optimal results.
