A study on the failure-diagnostic context-awareness middleware for wireless sensor networks

Abstract

We propose a middleware that diagnose any incorrect operation of a sensor or equipment occurring in the WSN application system adopting an indoor sensor network, and determines as to whether the incorrect operation is related to the reliability of the service offered by the system. The middleware proposed in this thesis makes up Data Management Module, Circumstance Information Related Module, Circumstance Analysis Module, Service Module, and Information Storage Module. The data retrieved from the interoperation between modules are analyzed through incorrect operation diagnosis algorithm, and thus it is determined whether a sensor or equipment operates incorrectly. © 2011 Springer Science+Business Media B.V.
