Integration of wireless sensor network and web services

Wireless Sensor Networks (WSNs) integrated with web services are becoming common in widespread applications across the world. WSNs are developed in different application domains of sensor and user types, with each typically relying on its own metadata semantics, data format and software. There is a high demand for standardising access to sensor data via internet without having to use some complex and unknown protocol. Thus, Service Oriented Architecture (SOA) is one of the key paradigms that enables the deployment of services at large-scale over the internet domain and its integration with WSNs could open new pathways for novel applications and research. The sensor web enablement initiative (SWE) within the Open Geospatial Consortium (OGC) has released a set of open standards for interoperable interface specifications and (meta) data encodings for the real time integration of sensors and sensor networks into a web services architecture. This paper describes integration of WSNs into a SOA by proposing a web service proxy linkage of the low level sensor platform to the high level SWE sensorweb architecture to treat sensors in an interoperable, platform-independent and uniform way.
