Abstract: Wireless Sensor Network (WSN) applications are traditionally developed on a per-case basis, offering very little reusability or extensibility. Any runtime variability in required data quality is at best addressed by parameterization, reconfiguration and rewiring of existing service compositions. These generic mechanisms can be further optimized if the same data is to be provided at various qualities, as is often the case in WSNs where multiple applications are interested in data from the same sensors. We propose the use of configurable components that may be concurrently used in multiple compositions and allow data quality properties to vary in each composition. Furthermore, the addition of new components or new clients does not affect existing dependencies. As a result we obtain efficient and flexible parameterization. In order to achieve this configuration mode, a patterned structure and behavior for all components is used which leads to fewer dependencies allowing for simpler reconfiguration of service compositions. A prototype implementation and an evaluation are included.
