Context adaptative systems based on horizontal architecture for ubiquitous computing

Many adaptative context-aware middleware exist and mostly rely on so-called vertical architectures that offer a functional decomposition for context-awareness. This architecture has a weak point: it leads to data centralization. Our mechanism for adaptation: the Aspects of Assemblies is based on a horizontal architecture. This type of architecture separate the system into behavior and is based on a decentralized approach. However, after having shown some limitations of AAs in the field of context-awareness we will introduce a way to improve them using a multi-cycle weaving approach. Then, using this approach we will be able to build context-adaptative systems that interact directly with their environment. Finally we will evaluate our approach in term of reactivity.
