Service Oriented Architecture for Context Perception Based on Heterogeneous Sensors Network

摘要

In this paper we will talk about the smart home concept. Even if smart home domain is not like the robotics domain, we can notice resemblances. In V. Ricquebourg et al. (2005), we shown that a smart home can be seen as a robot that turn over itself. A robot needs sensors to discover its environment. In the same way, a smart home needs sensors to watch in itself. This paper deals with a service oriented architecture of context perception for the smart home. In our approach, the smart house must be able to provide services adapted to the needs for its inhabitants. To answer to the needs, the environment, which will be described as smart, must take into account the context around the inhabitant: it will make it possible to provide contextualised services. Here, we present our service oriented architecture which integrates the various layers necessary to the determination of this context. Four layers are considered. Perception layer to obtain necessary information on the context, the context layer which makes it possible to give a sense to the perceived data, the inference layer which makes it possible to elaborate an artificial intelligence layer and to reason on the contextual data and the action layer which makes it possible to act following the decisions induced by the inference layer
