Research Focus

In addition to securing wireless communication systems and reducing their latency in a context of modernization, the Chair will ensure that this equipment can be deployed at less cost and in a nonintrusive manner over vast regions, notably in developing countries and isolated regions.

Three research themes will allow the Chair to reach this objective:

Low latency communication system

Reduce latency by influencing each stage of the communication chain. The results of this research will be applicable for wireless communications, ad hoc networks and fibre optic networks.

  • Rapid message detection strategy
  • Low latency relay channels
  • Low latency optic fibres
  • Mobile low latency ad hoc network

Research projected related to this theme
Strategy for timely detection of messages: for the receiver, low error high performance message detection can consume time, given the random nature of the message transmitted and the uncertainties and noise introduced by the network. The best decision made regarding the transmitted message is chosen following several analyses of a group of detection metrics that are sometimes iterative. This project seeks to propose an innovative solution to enable reliable and rapid detection of messages transmitted and thus the best response that enables optimization of the system's latency.

Low latency relay channels
: relay channels play a central role in wide coverage wireless systems. They allow intermediate multi-jumps for message transmission in a relatively dense network over long distances. They improve network coverage, but add latency and transmission delay, in addition to reducing the quality of the overall system. This project aims to propose innovative solutions to optimize latency with regard to relays in order to obtain wide coverage, low latency communication networks.

Low latency fibre optics: fibre optic networks are high-speed networks, but can be affected by too much latency that diminishes their performance. The techniques developed within the framework of this research theme to improve latency in a wireless communication chain can be of great benefit to fibre optic networks, notably for servers where better latency results in improved connection quality.

Security, analytics and connectivity at the gateway

The gateway, which is an essential element in a telecommunications network, permits the establishment of a contact between a client and servers, allows the transfer of requests over different protocols, message compression and decompression, and ensures security through access control, user authentication, authorization, etc.

  • Latency management by lead time scheduling
  • Integrated analytics at the Gateway
  • Cooperative analysis over the cloud
  • Intelligent interfaces
  • Quantum cryptography and chaotic modulation

Research projected related to this theme
Management of latency through scheduling: data packets travel through several stages before reaching their destination. Some packets are higher priority than others, and some transmission paths are longer than others. This research theme aims to propose integrated packet scheduling solutions for gateways based on a collection of well-defined criteria, in order to optimize latency management.

Integrated analytics at the gateway: the objective is to have a persistent status on the condition of the communication session, by integrating an analytical aspect with regard to the gateway, enabling the analysis and surveillance of the network's condition, including video quality, number of packets and calls dropped, etc. This analysis will allow better security management to protect against malware and real-time threats.

Collaborative analysis over the cloud: this includes pooling the analyses of data collected from various gateways using the cloud in order to determine in real time any weaknesses in the network and potential security threats and attacks.

Intelligent graphic interfaces: this theme aims to find solutions for intelligent gateway interfaces to allow better management of network analyses, firewalls, security and topology.

Quantic cryptography and chaotic modulation: this project will take advantage of the sensitivity of non-linear 'chaotic' generators to produce a sequence of random cryptographic keys that cannot be easily predicted. The use of these techniques may result in communications that are absolutely secures.

Low latency network architecture

The theories explored in the first two fundamental research themes will be put into practice.

  • Modernization of telecommunications infrastructures in developing countries
  • Deployment of a wireless network within the framework of the SmartLand project, in Ecuador
  • Development of heterogenous communication systems using satellite and terrestrial networks, dedicated satellite communications for broadband, and the terrestrial wireless network for the transmission of critical commands and data that require low latency

Research projected related to this theme
Developing countries (Harris system, SR Telecom): this project aims to revitalize various wireless legacy products in developing countries that will soon be outdated. Then an evaluation must be conducted on the strategies to upgrade these systems to optimize their interoperability with next-generation networks. The upgrading strategy should remain simple so that operators can keep the same spectrum bands. It should also propose technical characteristics similar to the legacy product, in addition to offering a timely return on investment for businesses. Various modern techniques will be tried out on the updated systems.

SmartLand equatorial project: this project targets the intelligent management of rural forest areas with wireless communication systems. With the collaboration of the UPTL, the Chair will help to equip rural villages with communications equipment and infrastructures that will enable them to manage their territory intelligently. The observation, analysis and measurement of various environmental aspects will help to better plan, manage and preserve their natural resourcess.

Hybrid systems, high-speed satellite links and low latency wireless communication: OneWeb, the new low Earth orbit 700-satellite constellation, Google Loon, the stratospheric helium-filled balloon project, and other new projects are seeking to find ways to provide Internet access around the globe.

The solutions proposed by the Chair will complement these projects. Wireless communications are so much faster than satellite communications, while the latter possess greater flow. This project will propose a hybrid solution that will use satellite communications for broadband and the wireless terrestrial network for the transmission of critical commands and data requiring low latency.

This system would benefit from the low latency offered by wireless networks and the techniques proposed within the framework of this study to send short, critical messages. Furthermore, the large data transfer capacity of the satellite system would permit high-volume transfers.
