Deployment Overview

The SENSEI Pan-European testbed realizes the SENSEI system for integrating heterogeneous sensor networks with the Internet. This section gives an overview of the testbed deployment, its main components and the roles played by various entities involved with the testbed. Finally, a short description about how the testbed works is given.

The figure below shows the deployment architecture of the testbed. The central components of the testbed are deployed on a data center. These components provide services like the resource directory, security along with semantic query interfaces for applications. Embedded devices and sensor networks interact with the SENSEI system using web interfaces for registering and accessing resources. The entity that makes resources on devices or in sensor networks available to SENSEI is called a Resource End Point (REP). Finally, applications can be developed that discover and use these resources. Unlike middleware solutions, SENSEI uses a decoupled approach based on the web architecture. Resources are discovered by making resource directory lookups or semantic queries, but are accessed directly using the resulting URL(s). A management GUI is provided with the central components in order to manage and test the whole system. For more information about the SENSEI architecture, see the ​SENSEI White Paper.
