Design of Autonomous Decentralized Mobility System: Implementation for ITS Services using DSRC

A group management model was previously proposed in which several base stations (BSs) autonomously judge whether to create a group in order to provide cruise-assist services, such as accident-reporting, and multimedia services, such as maps and music, for a moving vehicle by using multiple dedicated short range communication (DSRC) BSs flexibly and quickly. In this paper, an autonomous decentralized mobility system architecture to implement this model within an actual system is discussed. In this architecture, each BS autonomously judges whether to create a group for information provision. Each BS that participates in a group shares content regarding the vehicle and the service progress and provides information for the vehicle based on the urgency and the properties of the information. This paper also describes an evaluation of this architecture applied to test the actual system effectiveness.
