QoS-based probabilistic fault-diagnosis method for exception handling

Abstract

Fault-diagnosis is an essential prerequisite for exception handling. There are several attempts to apply it in the decentralized systems like Web Service. However, few of them discuss the fault-diagnosis technics along with QoS. In this paper, we base our work on an existing framework, and employ the Bayesian Network which takes QoS under consideration to operate a probabilistic analysis. We aim to evaluate the precedence of each diagnosis returned after the diagnostic procedure with a posterior probability and thus provide more support for exception handling. © 2011 Springer-Verlag.
