O meu nome é Helder Fontes e obtive o grau de Doutor em Engenharia Informática, pela Universidade do Porto, Portugal, em 2019. Sou Investigador Auxiliar na área de Redes sem Fios, parte do CTM, na qual estou integrado desde 2009. Desde essa altura já participei em projetos nacionais e europeus, incluindo o SITMe, Hiperwireless, FP7 SUNNY, SIMBED, SIMBED+ e ResponDrone. O meu doutoramento focou-se na Sinergia Simulação-Experimentação. Os meus interesses de investigação incluem simulação, emulação, e experimentação de redes sem fios no contexto de cenários emergentes como os aérios e marítimos, com especial foco em repetibilidade e reproducibilidade de experiências.

Abstract
In the past years, INESC TEC has been working on using ns-3 to reduce the gap between Simulation and Experimentation. Two major contributions resulted from our work: 1) the Fast Prototyping development process, where the same ns-3 protocol model is used in a real experiment; 2) the Trace-based Simulation (TS) approach, where traces of radio link qualities and position of nodes from past experiments are injected into ns-3 to achieve repeatable and reproducible experiments. In this paper we present ns-3 NEXT, our vision for ns-3 to enable simulation and experimentation using the same platform. We envision ns-3 as the platform that can automatically learn from past experiments and improve its accuracy to a point where simulated resources can seamlessly replace real resources. At that point, ns-3 can either replace a real testbed accurately (Offline Experimentation) or add functionality and scale to testbeds (Augmented Experimentation). Towards this vision, we discuss the current limitations and propose a plan to overcome them collectively within the ns-3 community. © 2019 ACM.
