Expressing and Configuring Quality of Data in Multipurpose Wireless Sensor Networks
Source: Katholieke Universiteit Leuven
Wireless Sensor Networks (WSNs) are evolving towards interconnected, sensing, processing and actuating infrastructures that are expected to provide services for multiple concurrent applications. In a multipurpose WSN, concurrently running applications share network resources and each may have varying Quality of Data (QoD) requirements. The authors' middleware targets these multi-purpose WSN deployments. Specifically this paper discusses how one should express and configure QoD properties for multi-purpose WSNs. They contribute by presenting their approach; which leverages per-instance QoD configuration and a separation of operational concerns to achieve simpler configuration and improve adaptability and customize-ability of the WSN. A prototype implementation and comparison to the related state of the art in WSNs are provided.
