Utilisation des réseaux de capteurs de canne pour les applications de surveillance de personnes

摘要

The world is undergoing profound demographic changes closely linked with the development of the field of public health. The increase in life expectancy is accompanied by an increase in the number of elderly people, in particular those with chronic diseases. Several existing research projects have as objective to ensure the maintenance to homes of the elderly, by a better follow-up by using new technologies. Among them, we find the proposed CANet who proposed the use of sugar cane as a tool for monitoring non-intrusive by the integration of a multitude of sensors. The cane used a wireless communication system, which allows him to exchange with a collection center or surveillance. This technological solution allows the respect of the private life of older persons, without limiting their freedom. Our thesis subject is inscribed in the framework of this project CANet. The work of this thesis is organized primarily around the design of an architecture protocol topology, and access methods for wireless networks, which allow monitoring of older persons through a network of sensors embedded in a cane. The main objective of the thesis is the study of architectures and protocols implemented at the level wireless communication to provide a reliable network infrastructure for various services for monitoring, measures, routing of data to a control center remote (medical office, members of the family, etc.). These proposals have been the subject of a theoretical study and analysis of performance by simulation.
