Abstract
Integrating wireless sensor networks (WSNs) into the service-oriented architecture poses many research challenges. One of these challenges is how to apply Web services to the resource constrained WSNs in terms of communication and computation capabilities. Another research challenge is how to build power-aware service-oriented data streaming for WSNs. This paper addresses serviceability issues of WSNs using the Web services resource framework (WSRF) under the open grid service architecture (OGSA). It also addresses the issue of power efficiency for sensor application services that are built on WSRF and provides a query optimization mechanism at Web services level based on the Markov decision process (MDP). We use a work-in-progress project involving condition-based maintenance (CBM) as an industrial application show case.
