Wireless Sensor Networks (WSNs) are a fundamental technology for science in many domains, and their inclusion in Web environments, e.g. through Web services, allows for their open/standard access and integration. Although such Web enabled WSNs simplify data access, network parametrisation and aggregation, the available interaction models and run-time adaptation mechanisms are still scarce. Nevertheless, applications increasingly demand richer and more flexible interface accesses, for instance, the interaction model dynamic adaptation according to contextual information. To this extent, this paper discusses the relevance of the session and pattern abstractions on the design of a middleware prototype providing richer interaction models, as well as a few context-based dynamic adaptation mechanisms for Web enabled WSNs. |
