About the research centre or Inria department
The Inria Lille - Nord Europe Research Centre was founded in 2008 and employs a staff of 320, including 280 scientists working in fourteen research teams. Recognised for its outstanding contribution to the socio-economic development of the Hauts-De-France région, the Inria Lille - Nord Europe Research Centre undertakes research in the field of computer science in collaboration with a range of academic, institutional and industrial partners.
The strategy of the Centre is to develop an internationally renowned centre of excellence with a significant impact on the City of Lille and its surrounding area. It works to achieve this by pursuing a range of ambitious research projects in such fields of computer science as the intelligence of data and adaptive software systems. Building on the synergies between research and industry, Inria is a major contributor to skills and technology transfer in the field of computer science.
The Inria FUN research group investigates solutions to enhance programmability, adaptability and reachability of FUN (Future Ubiquitous Networks) composed of RFID, wireless sensor and robot networks. Limited resources, high mobility and high security level evolving in distrusted environments characterize the objects that compose FUN. They communicate in a wireless way. To be operational and efficient, such networks have to follow some self-organizing rules. Indeed, components of FUN have to be able in a distributed and energy-efficient way to discover the network, self-deploy, communicate, self-structure in spite of their hardware constraints while adapting the environment in which adapting the environment in which they evolve.

In recent years, Ultra-Wide Band (UWB) technology became the basis for radiolocation [1,2] based on distance measurement thanks to the robust estimation of the time of flight between mobile nodes (tags) and fixed nodes (anchors). Unlike RSSI approaches, as used in BLE for example [3,4], the adopted metric is more robust to multipaths and relies on dedicated electronics for clock synchronization and time-of-flight measurement.
Nowadays, it is an integral part of the IEEE 802.15.4 standard at the physical layer and its growth positions it as a new technology in future smartphones. Indeed, it will complement the existing Bluetooth chips by offering a precise distance measurement capability useful for example for tracking  (pandemics for example) or any other LBS type application (Location-Based Services). The manufacturer Decawave, the originator of the Scensor radio chips (DWM1000) introduced certified radio modules [6,7] exposing BLE and UWB channels in the same chipset while integrating the antennas.
This opens up new possibilities for the Industrial IoT (IIoT), not only in the industrial world but also beyond. Radiolocation based on distance measurements is a well-studied research topic , but we know that a unified approach, as is the case for GPS, is not available off the shelf and that in order to better use to benefit from technology, optimizations must be made to measure according to the targeted application context. In particular, this requires evaluating the performance of distance measurement in the context of the application and designing or even adapting radiolocation algorithms.
In this area, Inria holds two patents [9,10] in the field of radiolocation. The use of  would in particular be studied to implement all or part of the solution to the problem of mesh reconstruction by distance measurements.

The Engineer will join a dynamic team of researchers and engineers working on the development of an end-to-end IoT solution for the vertical of maritime transport that is nowadays challenged by the increase of the maritime transport capacity as well as regulation requirements pushing to reduce the environmental impact due to container loss in the sea. The envisioned solution leverages the use of a novel real-time auto-localization with automatic device-container mapping, useful to identify and locate anomaly such as a fire or a fall.
The candidate will lead the hardware and firmware development of the IoT devices at the heart of the proposed IoT platform. This activity is at the core of the solution and combines the BLE Mesh networking and UWB ranging technologies for the network automatic localization in harsh environments with low cost and energy footprint.
The candidate will be in charge of
Firmware development on top of an embedded RTOS exposing BLE and UWB stacks
