Poster Abstract: Integrating Wireless Sensor Network and Enterprise IT Web Services

In the emerging Internet of Things a plethora of mostly resource constrained devices (e.g., sensor nodes) offering different services are integrated into the Internet. Thus, to flexibly use these services, which are often characterized by ad-hoc communication links, decentralized service discovery and self-description is needed. Due to the existence of different protocols, a protocol conversion to integrate WSNs into today's (IP-based) networks is essential. We propose an approach to efficiently realize self-description and dynamic discovery of embedded Web Services using a schema-based WSDL compression. Furthermore, we present an approach to convert between standard Web Service transport bindings such as SOAP+HTTP and optimized binding for WSNs using schema-based SOAP message compression.
