HANDBOOK 2 SUSTAINABLE CONSTRUCTION
To provide information about a new sensor measurement the Virtual Gateway should perform a
HTTP POST to the following URL:
http://:/i3con-manager/REST/
gateways//motes//sensors/
/measurements/
The data associated with the POST request must be an XML document containing details of the
measurement in the following format:
2010-01-05T09:30:00.000+00:00
100.0
If the POST request is successful the application will return a response with status code 200 (OK) and
a body containing an XML document describing the measurement, including an ID assigned by the
application. It should be noted that the virtual gateway passes data to the health monitor via the REST
interface as it is received from the motes.
Summary
In I3CON project, we have designed an architectural framework for WSN for monitoring of enterprise
buildings. We further have developed a REST-based style SOA to enable integration of the WSN
architecture with other enterprise services. In this paper, we briefly discussed the issues related to
WSN security and described the implementation of an access control service mechanism. We have
also described the implementation of an application for WSN operational health monitoring based on
the above architectural frameworks. The application has been deployed and is in use in TRT (UK)
WSN testbed and in Margaritas building in Madrid. There is also a plan to deploy WSN infrastructure
in a building in Seville, Spain. The captured WSN environmental data will be used by a number of
applications including the health monitoring.
