Abstract
In this study, we consider a chained computing system - a system that includes a large number of base stations, each with a very narrow communication area, that cooperatively deliver various services to mobile terminals in vehicles moving, at high speed. In operation, several autonomous base stations dynamically form themselves into a group on the basis of a service scenario received from a mobile terminal and profiles that describe the characteristics and the capabilities of each autonomous base station and autonomously deliver different kinds of services to the mobile terminal. First, we explain the basic model of a chained computing system and describe high-assurance, high-performance, and high-quality architectures that can be used for service delivery to a mobile terminal moving at high speed. Second, we discuss a Quality of Service (QoS) control method applied through these architectures to the roadside system, which is a component of the smart gateway system proposed by the Telecommunication Advancement Organization of Japan (TAO). We also discuss evaluation results concerning the QoS control method.
