A flexible web service based architecture for wireless sensor networks

Abstract

The current sensor networks are assumed to be designed for specific applications, having strongly coupled data communication protocols. The future sensor networks are envisioned as comprising heterogeneous devices assisting to a large range of applications. To achieve this goal, a new architecture approach is needed, having application specific features separated from the data communication protocol, while influencing its behavior. We propose a Web Services approach for the design of sensor networks, in which sensor nodes are service providers and applications are clients of such services. Our main goal is to enable a flexible architecture where sensor networks data can be accessed by users spread all over the world.
