Coordination mechanism for optimized provision of services in an area

We are aiming at achievements of the Unconscious Computing to provide users with ubiquitous services even if they are not conscious of ubiquitous computer environments. In the Unconscious Computing, a user's cellular phone recognizes the actions that the user should do. A server is installed in an area to know the number of resources such as buy-ticket places or ticket reservation counter and to manage the their usage status. When the user enters an area, his cellular phone provides the user with services which let him execute actions to require the resources through the server. However, it is difficult to provide services to all users if they are requesting services for the same resources from the same area. To solve this problem, this paper proposes the Action Arbitration Function to arbitrate the competition for resources. The Action Arbitration Function integrates the action schedules of the users competing for a resource, reschedules the actions, and provides services to a user who has a tight action in consideration of their future actions.
