Activities

In the recent years wireless technology has become an important part of our daily lives. As the demand of services from the users are constantly growing, current technology is pushed to its limits and new developments need to be addressed. In the Radio Networks research unit we want to contribute to this evolution by studying and developing algorithms for the lower layers of wireless networks.

For the moment, three areas are studied :

Research projects

ICMCIS

The ICMCIS is an international conference with 15 years of tradition. The intent of the conference is to create a forum for useful contacts and exchange ideas on development as well as implementation of advanced information and communications technologies and services in military systems. The conference gives a unique opportunity to discuss different points of view and share experience with colleagues from European and NATO nations involved in CIS. Previous conferences took place in many countries in Europe.

Steering Committee Chairman: Peter LENK, NATO Communications and Information Agency

Technical Program Committee Chairman: Bart SCHEERS, Royal Military Academy, Belgium

SafeShore

The main objective of the SafeShore project is to cover existing gaps in coastal border surveillance and increase internal security by preventing cross-border crime such trafficking in human beings and the smuggling of drugs. The project will develop an effective system to detect mini-RPAS when they cross the maritime border. To detect targets that are flying in low altitude, SafeShore will develop and deploy 3D LIDAR which will be integrated with passive acoustic sensors, passive radio detection and video analytics. The boats and humans on shore will be detected by a 2D LIDAR integrated with video analytics. Those technologies can be considered as low cost and ‘green’ technologies. One of SafeShore’s specific objectives will be to cover 1500-1800 meter along the coastal border.

The CISS department is responsible for the Radio passive monitoring system for detection and localization of small drones. The first part of this task is to determine the frequency in which the drone and the pilot operates. Once the frequency has been identified, an antenna array will be used to determine the angle of arrival of the transmitted signals.

Study of solutions against security threats in the context of cognitive radios

This thesis studies jamming and anti-jamming tactics using cognitive radio technology. This research is mainly based on Q-learning artificial intelligence algorithm and game theory models to deal with diverse jamming tactics. A Software Defined Radio/Cognitive Radio test bed architecture is used to develop, test and validate the proposed algorithm.

SIC07

The main objective of this study is to develop distributed time-slot assignment methods , and methods for time synchronization for tactical radio networks to have a fully functional TDMA based MAC, and evaluate their performance by simulations and by implementing on a hardware test-bench.

Course BIPT

Course on "introduction to digital telecommunications", given to the technical personel of the "Belgian Institute for Postal services and Telecommunications" (BIPT) - Ellipse Building - Bâtiment C - Boulevard du Roi Albert II 35 - 1030 Brussels.

The course involves 8 days of teaching and 4 days of lab sessions, during the month of June 2012.

ICARUS

ICARUS is a EU FP7 project on robot assisted search and rescue (SAR) operations. As one of the partners, the CISS Department contributed to the design and implementation of a wireless communications system to interconnect the unmanned platforms, command and control stations and rescuers. The key objective was to obtain a self-organizing network of mobile devices adapting to the dynamics of the environment.

F11/01

Automation of audio processes in the collection of operational SIGINT.

MRC04

The aim of this project is to study the performance measures (throughput, delay, jitter) of Packet Data Radio Networks (PDRN). PDRNs will form the mobile backbone of the tactical communication network for the next generation of combat systems. Analytical and simulation models are combined to evaluate the characteristics of both synthetic and captured traffic streams considering a realistic scenario, i.e. the topology of the radio means and the physical surroundings.

F09/05

This study mainly focusses on how to retrieve the position of the sensor nodes of a wireless sensor network and with which precision this can be done (assuming the nodes don’t have a GPS module on board). How the topology of the wireless network could be controlled in order to optimise the network for given scenarios is also investigated. The goal of this study is not only to have a theoretical approach of the problem, but also to implement the most promising methods or algorithms on a real sensor network.

C4/19

In this study, three main objectives are pursued: 1) make a state-of-the-art survey of software radio techniques and cognitive radios, 2) contributing in the domain of spectrum management for cognitive radios in the UHF and VHF frequency bands and 3) contributing to waveform design for cognitive radios in a adhoc tactical network context.
