A Design of Sensor Web Registry for Wireless Sensor Networks with SOA Approach

Advancements in the MEMS technology, improved deployment strategies and sensor Web enablement standards, have facilitated the realisation of pervasive and ubiquitous computing through more and more sensor networks. Research community is straining hard to establish world wide sensor networks that may provide functionalities similar to those available through Internet and World Wide Web. A serious look on the whole scenario reveals the importance of providing a centralised or distributed registry for the fixed and nomadic sensor networks. SOA, the proven technology in the information processing can be very well considered for design and implementation of an efficient sensor Web registry. This paper attempts to design such registry by describing the fields needed in such registry and presenting various sensor description Web services which are part of the process or process chain. Further, the Schema and WSDL are also developed for a sensor network description service. The goal is to evolve a framework which can be utilised by developers to collaboratively work on a huge array of sensor networks and have access to the wider problem domain.
