M.: Interoperation, composition and simulation of services at home

Abstract. Pervasive computing environments such as our future homes are the prototypical example of a dynamic, complex systemwhere Service-Oriented Computing techniques will play an important role. A home equipped with heterogeneous devices, whose services and location con-stantly change, needs to behave as a coherent system supporting its inhabitants. In this paper, we present a fully implemented architecture for domotic applications which uses the concept of a service as its funda-mental abstraction. The architecture distinguishes between a pervasive layer where devices and their basic internetworking live, and a composi-tion layer where services can be dynamically composed as a reaction to user desires or home events. Next to the architecture, we also illustrate a visualization and simulation environment to test home coordination sce-narios. From the technical point of view, the implementation uses UPnP as the basic device connection protocol and techniques from Artificial Intelligence planning for composing services at runtime
