Abstract

In this letter, we investigate the impact on connectivity metric when a power-saving model is applied to a vehicular network. An analytic model with linear time complexity is developed to compute the optimal number of active roadside units under a connectivity constraint. We provide guidelines for applying a power-saving model in a vehicular network. The results are very useful for the ministry of transportation.
