About

I started my doctorate degree at the Université de Lille-Sciences et Technologies- in October 2019, concurrently working as a research assistant at Inria - Lille Nord Europe - equipe FUN, under supervision of Prof. V. Loscri. The thesis subject is entitled as " Communication Protocols based on alternative paradigm for wireless mobile devices" where we optimise communication protocols for complementary technologies (VLC) to traditional radio networks.

As a part of the team objectives I am interested in these areas of research:

Wireless Communications
Vehicular Communications and ITS
Visible Light Communications and mmWaves
Data Link Protocols
IoT-Smart City Applications

Optical communication is any form of telecommunication that uses light as the transmission medium. Having originated in ancient times in the form of beacon fires and smoke signals that convey a message, optical wireless communication (OWC) has evolved to a high-capacity complementary technology to radio frequency (RF)
communication. OWC systems utilize wavelengths in the infrared (IR) spectrum for IR communication and the visible light spectrum for visible light communication (VLC). Because of the availability of a huge license-free spectrum of approximately 670 THz, OWC has the potential to provide wireless links with very high data rates. In this book, optical modulation schemes, as well as signal processing and networking techniques, are presented to maximize the throughput of optical wireless networks using off-theshelf
components.

Visible Light Communications

Vehicular Communications

The vehicular communication system includes vehicles and other communication entities around it such as roadside units, clouds, grid and fog networks, the Internet, devices carried by an individual and a pedestrian, etc. The objective of vehicular communication is to ensure road safety, avoid road accidents, reduce fuel consumption and carbon emissions, save time and offer a new level of driving comfort. To achieve these goals, information is exchanged between vehicles and other communication entities. This type of communication is referred to as Vehicle-to-everything (V2X) communication . It incorporates communications such as Vehicle-to-Vehicle (V2V), Vehicle-to-Infrastructure (V2I), Vehicle-to-Network (V2N), Vehicle-to-Pedestrian (V2P), Vehicle-to-Device (V2D) etc.

Inria

The Inria Lille-Nord Europe Centre, created in 2008, is based on two sites: one on the University of Lille campus at La Haute-Borne and one in the midst of the EuraTechnologies entrepreneurial ecosystem.

Context

Generally, the cooperation among heterogeneous devices is based on information acquired through the communication among the nodes. Traditional communication paradigms are based on link through electromagnetic fields waves (i.e. electromagnetic radiation), but alternative communication paradigms can be envisaged to improve efficiency, energy consumption and ubiquitous concept. For example, one can think to exploit the already available (to illuminate) LEDs that could be conveniently used to acquire useful information based on different emerging communication paradigm such as the VLC. A different communication paradigm could have inherent advantages in respect of the traditional approaches such as: 1) An environment where a “traditional“ communication paradigm is difficult (e.g. environments too noisy with too many interferences); 2) Data rate could be higher than traditional communication (e.g. as in the case of the VLC paradigm); 3) The possibility to design and implement “smart“ devices, that could adaptively select the best way to communicate based on their proper current status, the status of the neighbours and the surrounding conditions4) The integration of mechanisms to make the communication system robust to attacks (e.g. Denial of-Sleep attacks, eavesdropping).

Thesis

At the beginning, we reviewed the literature, by focusing on different and alternative (in respect of traditional techniques) communication paradigms. We were supported in the definition of the requirements of the system aimed at supporting a new communication paradigm, benefited from the background and expertise of the team in this context, acquired in the last years and that dealt with the implementation of two testbeds. The first one is concerning a VLC communication system where an Artificial Intelligence (AI) approach has been developed on top of the receiver (a photodiode) in order to manage control parameters to reduce the Bit Error Ratio (BER).The other test-bed is implementing an indoor geo-localization system with a mobile user (i.e. the transmitter) that has to be geo-localized. The final part of the doctoral program will be devoted to the design and implementation of a communication protocol based on a specific novel communication paradigm. The PhD candidate will be asked to analyse and identify some specific evaluation parameters, in order to define the goodness of the protocol and the critical issues in terms of security, by analysing some specific types of attacks such as for instance Denial-of-Sleep attacks, eavesdropping. Moreover, a potential approach that could be exploited would be the implementation of some machine learning techniques to be directly integrated in the devices, in order to develop effective, efficient and secure cooperation mechanisms among the nodes

FUN

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.
