Abstract

The current wireless sensor networks (WSN) are assumed to be designed for specific applications, having data communication protocols strongly coupled to applications. The future WSNs are envisioned as comprising of heterogeneous devices assisting to a large range of applications. To achieve this goal, a flexible middleware layer is needed, separating application specific features from the data communication protocol, while allowing applications to influence the WSN behavior for energy efficiency. We propose a service-based middleware system for WSNs. In our proposal, sensor nodes are service providers and applications are clients of such services. Our main goal is to enable an interoperability layer among applications and sensor networks, among different sensors in a WSN and eventually among different WSN spread all over the world.
