integrating wireless sensor networks into web service-based business processes
Wireless Sensor Networks (WSNs) are envisioned to become an integral part of the Future Internet where they extend the Internet to the physical world. Yet, while Service-Oriented Architectures (SOA) are prospering in Enterprise-IT, wireless sensor networks have -- despite contrary prognoses -- not found their way into enterprises. A major obstacle is certainly the different and resource-constraint nature of this class of devices. We argue that approaches for the seamless integration with existing, widely deployed SOA technologies such as XML, Web Services, and the Business Process Execution Language (BPEL) are key to the success of WSNs in enterprises. In this paper, we present our approach to integrate WSNs into SOA environments using these technologies in a resource-efficient but fully standard-compliant way. We evaluate our implementation and present a case study.
