This paper analyzes the information delivery delay for the purpose of roadside unit (RSU) deployment in a vehicular ad hoc network (VANET) with intermittent connectivity. A mathematical model is developed to describe the relationship between the average delay for delivering road condition information and the deployment distance between two neighbor RSUs. The derived mathematical model considers a sparse highway scenario where two neighbor RSUs are deployed at a distance without a direct connection, and vehicles are sparsely distributed on the road with road condition information randomly generated between the two neighbor RSUs. Moreover, the model takes into account the vehicle speed, the vehicle density, the likelihood of an incident, and the deployment distance between two neighbor RSUs. The correctness and accuracy of the derived mathematical model is verified, and the impacts of different parameters on the average information delivery delay are investigated through simulation results. Given an information delivery delay constraint for time-critical applications, this model can be used to estimate the maximum deployment distance allowed between two neighbor RSUs, which can provide a reference for the deployment of RSUs in such scenarios.
