Gamma-Reload Deployment: Planning the communication infrastructure for serving streaming for connected vehicles

Abstract

Intelligent Transportation Systems may highly benefit from the development of communication networks integrating vehicles. In this work, we study the deployment of roadside units for delivering streaming for connected vehicles. We consider that the proper dissemination of streaming requires a given share of vehicles periodically meeting the communication infrastructure located at the roadside in time intervals smaller than a given threshold. By considering the share of vehicles and time threshold, we propose the Gamma Deployment strategy for defining the location and number of roadside units required for providing the specific coverage. After that, we extend the proposed strategy to also consider the data transfer rate that vehicles receive data from roadside units, and also the data consumption rate of streaming inside vehicles, and so, deriving the Gamma-Reload Deployment strategy. We compare the proposed strategies to the intuitive strategy of locating roadside units at the densest locations of the road network, and the results reveal that the proposed strategies may achieve significant economy on the costs for setting up the communication network, while providing similar QoS.
