Wireless Sensor Networks provide unprecedented possibilities for monitoring and interacting with the real-world. Unfortunately, the lack of open and simple standards for ad-hoc collaboration between heterogeneous embedded devices makes it difficult to build large-scale deployments; every particular application requires complex integration work, and therefore technical expertise, effort and time. Inspired by the success of Web 2.0 mashups, the authors propose a similar lightweight approach for interacting with networked devices. In particular, they describe a gateway architecture that enables to access sensor nodes through a RESTful interface.
