A Service-oriented Middleware for Pervasive Computing Environments

Wireless networks provide limited reliability and less bandwidth than fixed networks for mobile nodes. And all mobile nodes are highly energy dependent as they use batteries with a limited capacity. Because of their physical portability, they can be used even when they move. This may require using different wireless networks while the node is moving. In order to provide users with the best possible services within the available resources, there is a demand to develop an intelligent mechanism to manage these limited resources. In this article, a context-aware middleware architecture is proposed to provide satisfactory services to end users of mobile nodes. Each part of the middleware architecture is introduced, and a case study is presented to show that the proposed approach is feasible to provide end user satisfactory services
