Dynamic Conflict Detection and Resolution in the Ubiquitous Service System

Abstract

In this paper, a Conflict Control Manager (CCM) for a ubiquitous services system is presented to prevent the mode confusion of humans. CCM consists of a lock-based conflict detection module and a D-PRI (dynamic priority)-based conflict resolution. By means of CCM, the mode confusion can drastically be reduced, and, as a result, CCM can assist in designing and implementing a human-centered ubiquitous environment. Through a case study, it is observed that CCM can successfully detect and resolve the runtime conflicts caused by multiple devices interconnected in a ubiquitous environment. It can also be used to detect the potential conflict risk during the service registering phase so that computerized devices are deployed to improve the human interactions with them.
