Competitive Wireless Access for Data Streaming over Vehicle-to-Roadside Communications

This paper considers the problem of optimal and competitive wireless access for data streaming over vehicleto-roadside (V2R) communication. In a service area, the onboard units (OBUs) in vehicles use wireless access to download streaming data from the roadside units (RSUs). The downloaded streaming data can be stored in proxy buffer for the application to playout. The wireless access can be in reservation or ondemand mode. While the price of wireless access in reservation mode is fixed, that of on-demand mode is determined from the total demand from all OBUs. The OBUs compete with each other for wireless access to a particular RSU. The objective of an OBU is to minimize the cost for wireless access while the quality-of-service (QoS) requirement (e.g., buffer underrun probability) of the streaming application is met. A stochastic game is formulated to model this competitive situation in which OBUs are the players of this game. The strategy of an OBU is the wireless access policy (i.e., ...
