The creation of digital twins of experimental testbeds allows the validation of novel wireless
networking solutions and the evaluation of their performance in realistic conditions, without …

Digital twins have been emerging as a hybrid approach that combines the benefits of
simulators with the realism of experimental testbeds. The accurate and repeatable set-ups …

In wireless networking R&D we typically depend on experimentation to further evaluate a
solution, as simulation is inherently a simplification of the real-world. However …

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 …

A common problem in mobile networking research and development is the cost related to
deploying and running real-world mobile testbeds. Due to cost and operational constraints …

In wireless networking R&D we typically depend on simulation and experimentation to
evaluate and validate new networking solutions. While simulations allow full control over the …

To properly validate wireless networking solutions we depend on experimentation.
Simulation very often produces less accurate results due to the use of models that are …

Network digital twins (NDTs) facilitate the estimation of key performance indicators (KPIs)
before physically implementing a network, thereby enabling efficient optimization of the …

The increasing need of wireless communications in emerging scenarios, including aerial
and maritime, requires the development of new protocols and the enhancement of existing …

One of the main strengths of Network Simulator 3 (ns-3) is the availability of modules to
simulate cellular networks, including LTE and mmWave/NR deployments. These …
