HI3 Project: Design and Implementation of the Lower Level Layers

We are interested in the development of human-centered and ubiquitous technologies in social environments. In this line, and in the framework of a global software architecture (HI
³
) for this type of applications, the paper is devoted to the presentation of the work carried out for the design and implementation of the layer that is more closely linked to the hardware. It is in charge of communicating with the physical layer and it is responsible for the abstraction of the field elements. Special attention has been paid to the coherence with the philosophy, design premises and functionalities of the whole system. We have also determined a hardware configuration that, integrating standards where possible, is better adapted to the requirements of the architecture. The elements introduced here were validated on a real implementation of the system.
