Abstract

Perception of a ubiquitous system is based solely upon sensor and device readings. The system decides to provide adequate services based upon these readings. We define a system of fault detection in the perception mechanism of a ubiquitous system based upon Bayesian networks and the combination of beliefs from independent networks. The proposed scheme is distributed and adequately suits the functioning of a large multi-domain ubiquitous system. Eradicating faulty percepts and identifying the malfunctioning device would improve the quality of service, and make the system more reliable.
