More and more devices of our daily life are computer-based. The normal development direction has turned from isolated and purpose-specific devices to collaborative and multi-purpose devices.
Many technologies were developed in parallel. Furthermore, many categories of devices have their own standards and means of communication.
The objective of this work is to provide a home-automation system. The system is based on the design of the HomePort system. It was designed to offer a distributed communicating architecture that provides an added value. It is open to new vendor\'s devices. It uses a layered and service-oriented architecture to fulfill its goals.
Thereafter, various solutions to problems that were left for future work in the initial HomePort architecture are described. Solutions include the automatic discovery and configuration of the components of the system.
Additionally, it includes the description of different security mechanisms, at various system levels, compatible with the rest of the system. The diverse solutions are presented, analyzed, and criticized according to the system\'s requirements.
Techniques to make the system redundant and scalable are described.
Finally, these new facets are implemented to be tested.
