Coupling Enterprise Systems with Wireless Sensor Nodes : Analysis , Implementation , Experiences and Guidelines

This paper presents an approach for closely coupling enterprise systems and tiny wireless sensor nodes that are embedded into physical items. Coupling is done by implementing services from the enterprise system on the wireless sensor node system and by letting part of the business logic run on the nodes. The paper analyses concrete application scenarios and discusses implications of this approach. The discussion is underpinned by implementation and testing of demonstration applications. The collected experiences lead to four guidelines a designer of such a system should follow.
