“…Performance has been identified as the most critical attribute of quality by many researchers [6], and Srivastava and Koehler [8] also described the real demand for robust and verifiable web services with high performance from industry. Our experience in the Gator Tech Smart House [13] further confirms that poor performance in service adaptation can seriously hinder the efforts to adopt service-oriented architecture as the solution for pervasive computing.…”

Service-oriented architecture (SOA) promises an elegant model that can easily handle dynamic and heterogeneous environments such as pervasive computing systems. However, in reality, frequent failures of resource-poor and low-cost sensors greatly diminish the guarantees on reliability and availability offered and expected by SOA. To provide a framework for building fault-resilient service-oriented pervasive computing system, we present a solution that includes a virtual sensor framework and a high performance service composition solution based on: (1) WS-Pro, a probe-based performance-driven service composition architecture, and (2) an abstract service composition template (ASCT) approach. The concept of virtual sensor enhances the availability of services, while the service composition solution ensures the system can efficiently adapt to changes and failures in the environment. This approach also includes a novel probebased monitoring technique to actively collect performance data, and the use of an extended Petri net model, FPQSPN, to model performance of service composition.

“…Both work do not address actuator integration and discovery. The Gator [6] platform treats sensors and actuators as service objects, providing development environment to programmers, unlike our approach which is designed for the less technically minded. In addition, the Gator work does not consider dynamic aspects of the home care environment.…”

“…Existing solutions to specifying actions often rely on developer-defined service interfaces [6], assume a set of predefined services [1], or consider that an administrator can somehow pass the low-level protocol-specific parameters to the ordinary user who can supply them when editing the rules [2]. None of these is a good solution with regard to deployment of home care systems.…”

Abstract. Home care systems need to be personalised to meet individual needs, and must be easily adjusted as the user's symptoms develop. Care policies (i.e. Event-Condition-Action rules) can be used to specify care services, facilitating changes in the behaviour of a home care system. Context modelling allows a user to specify the trigger and conditions of a care policy, using high-level context rather than raw sensor data. The actions of a care policy are, however, still dependent on the implementations details of actuators. We propose a framework that allows the actions of a care policy to be specified abstractly using human-understandable concepts. The framework takes care of discovering and using specific actuators, hiding the low-level home networking details from ordinary users. It therefore makes personalisation and modification of home care systems more accessible to ordinary users, requiring very little technical knowledge.
