Semantics-based Plug-and-Play Configuration of Sensor Network Services

A sensor network is expected to provide effective delivery of its services by taking an appropriate action based on one or more situations that it senses in the environment. However, due to the dynamism of application requirements and user context, it is often required to re-configure services from a sensor network to meet specific application needs. This paper is an attempt to enable dynamic adaptation of sensor network services to environmental changes with minimal human intervention. We propose a semantics-based architecture that uses a publish/subscribe pattern to enable self-configuration of sensor network services and potentially alleviate the heavy burden of programming sensor networks. We envisage an environment with the plug-and-play concept, where sensor networks, sensor nodes and sensors are dynamically reconfigured, ensuring minimal disruption to the delivery of higher order information services. We thus allow a client application to interact with the system and uniformly access sensor services, yet hiding the complexity of the system.
