A self-organizing management platform for wireless sensor networks

Through advances in sensor, networking, semiconductor and energy storage technologies, Wireless Sensor Networks (WSNs) are increasingly being deployed in many important applications to enable users to access information about the physical world. As a result, WSNs role as one of key components of the Internet Of Things. However, the increase of number of sensors, the number of sensor types, and the number of applications will make very difficult for the management systems of WSNs. In this thesis, we propose a self organizing management platform designed to ensure sensor nodes and user applications are set up and running as intended. Our management platform, called DISON (DIstributed Self Organizing Network) uses a multilevel management schema to provide scalability for large sensor networks. We show how sensor nodes self adapt to the changes in network resources and application requirements and how network resources are coordinated efficiently among groups of adjacent sensor nodes. For flexibility, our platform are implemented and performed in an independent layer and interact with the user application and network protocols through public interfaces. This helps our platform to be easily integrated to an existing or a new application. A set of management data models and protocols are developed to validate the efficiency of the proposed platform in resolving challenging management problems in both single and shared sensor networks. Finally, in order to qualitatively evaluate our platform, we present two case studies, one with a single sensor network and another with a shared sensor network, where DISON was used to coordinate network resources and application requirements. The results from extensive experiments show that using DISON can bring a dramatic improvement to the scalability, the stability, the efficiency, the reliability and the flexibility of WSNs. ; Gracias a los avances en la tecnología de sensores, redes, semiconductores y almacenamiento de energía, el uso de las redes de sensores inalámbricos (WSNs) ...
