Deescription lookup based UPnP extension for wireless sensor networks

Established service discovery protocols such as UPnP allow control points to find devices and services and to retrieve descriptions about them in order to learn all about the device and services. However, general device-control point approaches are not suitable for wireless sensor networks due to severe resource constraints and gateway architecture. To alleviate the problems we change discovery processes: 1) sensor node announces uniquely assigned identifiers; 2) base station retrieves additional descriptions for sensor nodes using lookup facilities; and 3) control points communicate with the base station to browse a list of descriptions and to send control commands to sensor nodes via standard UPnP protocols. In this paper we introduce our description lookup-based UPnP extension system for wireless sensor networks.
