Services Inside the Smart Home: A Simulation and Visualization Tool

Abstract

Pervasive systems, and domotics in particular, is an application area where heterogeneity is the norm, with thousands of autonomous heterogeneous devices live together and need to interoperate. One of the greatest difficulties in developing middleware for smart homes is that this kind of systems are extremely difficult to test and verify. We propose to reduce the testing costs by replacing actual home services with virtual stubs behaving as if they were actual hardware installed somewhere in the house and, most importantly, to visualize the behaviour of the home to give the user the impression and feedback of being in a real home.

A Tool for Integrating Pervasive Services and Simulating Their Composition

“…The major challenge for such tools is to integrate highly heterogeneous components and to provide a link with the physical environment. We extend our previous work on the RuG ViSi tool [4], in a number of ways: first, we provide a customizable and interactive middleware based on open standards (UPnP and OSGi) [3]; second, we allow any composition engine to guide the simulation and visualization (not only predefined compositions using BPEL) [3]; third, the interaction with simulated or physical devices is modular and bidirectional, i.e., a device can change the state of the simulation. In the demo, we use an AI planner to guide the simulation, a number of simulated UPnP devices, a real device running Java, and a two room apartment.…”

“…The simulation and visualisation platform -the RuG ViSi toolis an extension of our initial work presented last year at the ICSOC Demo session [4]. It is based on Google SketchUp for the 3D rendering.…”

The Differences and Commonalities between Green and Conventional Business Process Management

“…If such sensors are not available, due to the use of third party services for instance, assumptions must be made. Sensors can be provided, for instance, by specific web services which enable the information integration into existing event infrastructures [22]. In some cases, a sensor is insufficient as data cannot be provided based on simple measurements.…”

Coordinating the web of services for a smart home

“…In Lazovik et al [2009] we used a BPEL engine to demonstrate some complex scenarios on the visualization platform. In Redondo et al [2008], composite services deployed as BPEL processes are made available in a semantically enriched OSGi platform.…”
