Abstract : The strong urbanization witnessed by the world requires better management of cities. This improved management involves the monitoring and maintenance of urban infrastructures and equipment to ensure greater safety and well-being for residents. To achieve these objectives, a key role has been given to Information and Communication Technologies (ICT) through the concepts of Internet of Things (IoT) and Smart Cities. As a result, we have seen a growing number of data capture devices integrated into different parts of the city to deliver dedicated services and applications. However, given material, technological, economic and environmental constraints related to the nature of the devices in use, the objectives of total coverage and management of urban infrastructures is still hindered. This thesis is positioned in this context and proposes Radio Frequency Identification (RFID) in addition to the techniques already in use to overcome these shortcomings. However, the adoption of large-scale RFID for urban centers requires solving two main issues: reading collisions and data collection and forwarding. Through the work carried out in this thesis, we first sought to identify the solutions already proposed in the literature to reduce collisions. Based on this study, we proposed two distributed anti-collision algorithms named DEFAR and CORA. They provide high throughput while maintaining low collision and latency rates compared to literature solutions for dense and/or mobile deployments of RFID readers. Subsequently, we proposed DACAR, a distributed algorithm for multi-hop data collection using RFID readers. This protocol is adaptable and according to the anti-collision protocol used and the position of deployed readers, provides a reliable packet delivery ratio and low end-to-end delay. An improved version of DACAR is later proposed that takes into account the prioritization of data to provide different, improved and more suitable paths using a combination of different parameters through fuzzy logic.
