Thesis abstract :

This thesis focuses on the development of tools and methods dedicated for ultra wide band (UWB) localization systems in indoor environment. The thesis work was conducted within the European FP7 project Where2, about the cooperative localization in cellular networks. Data from a measurement campaign conduct during the project are used to validate the proposed algorithms. This thesis is divided in four parts:

The first part is focused on the description of an original raytraing tool based on a graph description. In order to be compliant with the requirement of a mobile simulation, a new concept of rays signature enabling incremental computation, and a vectorized formalism for processing rays are described and implemented. The second part is focused on the indoor local- ization techniques, where a novel technique based on interval analysis approaches is presented and compared to alternative techniques. Advantageously using this approach, a specific pro- cessing based on an hypothesis testing method using received power observations to resolve ambiguities appearing in under determined localization problems is described. A third part describes different aspects of the dynamic platform. In particular a realistic mobility model based on «steering behaviors», a graph description of the network scene and an inter agents communication protocol are detailed. The fourth section uses measured data obtained from an heterogeneous measurement campaign to validate both the developed software platform and the proposed localization algorithms.

European Projects

  • FP7 UCELLS

The main objective of UCELLS project is to study and to demonstrate the Cellular UWB capabilities employing a spectrum monitoring system based on a high performance ADC in order to efficiently enable coexistence and compatibility of UWB-based wireless communications with existing and future mobile and fixed wireless systems.

  • FP7 WHERE 2

The WHERE2 project is a successor of the WHERE project and addresses the combination of positioning and communications in order to exploit synergies and to enhance the efficiency of future wireless communications systems. The key objective of WHERE2 is to assess the fundamental synergies between the two worlds of heterogeneous cooperative positioning and communications in the real world under realistic constraints. The estimation of the position of mobile terminals (MTs) is the main goal in WHERE2. The positioning algorithms combine measurements from heterogeneous infrastructure and complement them by cooperative measurements between MTs, additional information from inertial sensors, and context information. Based on the performance of the geo-aided positioning strategies (in the sense of accuracy, complexity, overhead of signalling, reliability of the provided information, etc.) the impact on coordinated, cooperative, and cognitive networks is assessed. This is done under realistic scenarios and system parameters following on-going standardization processes. A joint and integrated demonstration using multiple hardware platforms provides a verification of the performance of dedicated cooperative algorithms.

WHERE2 is an international project co-funded by the European Commission within the Seventh Framework Programme. The project team comprises the following organizations:
German Aerospace Center (DLR) – lead, Aalborg University, ACORDE, Commissariat à L’Énergie Atomique – LETI, Institut Eurécom, Siradel, Université de Rennes 1, Instituto Telecomunicações, Mitsubishi Electric ITE, Sigint Solutions Ltd., University of Surrey, Universidad Politécnica de Madrid, University of Alberta, City University of Hong Kong, Telefónica I+D, Hellenic Telecommunications Organization (OTE S.A.), University of Athens.

Résumé

I’m currently Ph.D Student at the Rennes research institute for Electronics and Telecommunications (IETR), France. My research seek to contribute to indoor localization. My work is especially focused both on the indoor positioning using set- membership approaches and to the channel modeling . My Ph.D thesis work also contributes to the FP7 WHERE 2 European Project.

Previously, I have worked as a research engineer at the Rennes research institute for Electronics and Telecommunications (IETR) . I was involved in the FP7 UCELLS project for UWB positioning.

I received my master’s degree in Electronics and communication devices from the National Institute of Applied Sciences (INSA) of Rennes, France, in 2007
