On the Integration of Service-Oriented Architectures and Sensor Networks

Currently, two major trends are gaining momentum: Service-Oriented Architectures (SOA) based on Internet standards are widely deployed in industry and Wireless Sensor Networks (WSNs) are becoming an integral part of the Future Internet. Combined, these two trends lay the groundwork for a new class of applications where all kinds of devices ranging from simple sensor nodes to large-scale application servers interact to drive business processes not possible before. That way, data stemming from a WSN monitoring assets in a port area influence the control flow of a business process in real-time or even trigger a business process. To achieve this level of integration, WSNs must seamlessly interoperate with existing widely deployed SOA technologies such as XML, Web Services, and the Business Process Execution Language (BPEL) to name only a few. However, due to their high ressource demand, these technologies are hardly applicable in resource-constrained WSN environments. In this paper, we present a survey of existing approaches and introduce our technique to seamlessly integrate WSNs into SOA environment using only very few resources.
