Supervision de réseaux d'objets intelligents communicants sans fil

Abstract : Thanks to the advanced in wireless access medium, MEMS and VLSI technologies in the last decade, a new research area, which is considered as one of the key technology of the 21st century is emerged: Wireless Sensors Networks (WSNs). WSN is a high resource constraints embedded systems such as energy and processing power. Their application fields are huge, which may be applied from environmental data collection to disable people assistance. A typical application can contain about ten or thousand of wireless sensors nodes. The challenge of this thesis is to provide a simple and intrusive-less technique to manage efficiently WSNs. To meet these requirements, it is important to minimize the impacts of WSN administration tasks on the operation of every sensor node and network traffic. Thus, we proposed a new technique named LiveNode Non invasive, Context-aware, and Modular management (LiveNCM). LiveNCM is a SNMP like WSN management tool. The main features of LiveNCM are to provide methods, which enable to know every node status by taking into account the application context and by implementing sample data estimators to minimise message exchanges. Note that, the wireless message exchanges are energy consuming, so by minimizing message exchanges, we increase significantly the WSN lifetime comparing with the traditional techniques ones. The results obtained from a real application: environmental data collection, shown that LiveNCM is energy efficient because it enables to double the WSN lifetime. Moreover, by minimizing the message exchanges in the network, LiveNCM limits message sending collisions and network traffics. Thus indirectly, LiveNCM improves significantly the QoS of WSN.
