The exponential growth of wireless devices connected to the Internet and the limitation of the available electromagnetic spectrum requires the optimization of resource scheduling and frequency reuse to provide a better quality of service. New applications from the evolution of wireless networks, especially the 5G network, consider the use of cognitive radios and the sensing of the spectrum as fundamental elements in its development. The advance and development of new technologies depends on simulation environments that facilitate and integrate tools to evaluate the various applications and scenarios of 5G networks. This article presents a collaborative sensing module and a cognitive resource scheduler for the LS module of the ns-3 network simulator.
