My contribution to the development of the Algerian School of Performance Evaluation of Computer Systems and Telecommunication Networks, can be appreciated through the work of the EPSIRT research team (which I founded in 2006 as an independent group , and which was approved as a research team in 2009). His work mainly concerns the improvement of performance and the guarantee of the quality of service of systems and networks with strong constraints, contributing to the evolution of advanced technologies (WSNs, STIs, IoT, IIoT, IoV, ...).
