Generic sensor network gateway architecture for plug and play data management in smart laboratory environments

During the last years, recent technological advances enabled the development of tiny devices equipped with radio, micro controller and sensors, called sensor nodes. Collaborating networks of such devices, known as wireless sensor networks (WSNs), are subject of many researches. A couple of network centric tasks like data transmission and aggregation, self-organisation, localization and energy awareness have been focused in various publications. Researches, e.g. IPv6 over low power WPAN (6LoWPAN), are going to standardize the connection of sensor nodes with common Internet protocols. Nevertheless, until now proprietary techniques are used within most networks, especially for the coupling towards the outside world as well as the data management. Depending on WSN hardware and software, the gateway software as well as storage and presentation of data differs for most sensor networks. In this work we present an infrastructure which bases upon a generic gateway. Standardized dataset will be stored by this device using sensor Web enablement (SWE) and standard protocols. By use of devices profile for Web services (DPWS) plug and play abilities as well as a comfortable query interface for presentation is realized.
