Abstract


This work presents COLAB-5, a tool developed for the NS-3 system simulator, which allows the simulation of different scenarios in 5G networks. The tool was modeled by following a modular approach that allows the incorporation of physical layer characteristics in the simulator through a pre-defined interface and JSON technology. The results produced by a physical link level simulator - in this case 5G for remote areas - are incorporated into the NS-3 simulator. This approach allows the simulation of varied scenarios in NS-3 and reduces the computational complexity by simulating different scenarios. COLAB-5 also implements CR (Cognitive Radios) techniques in the NS-3 MAC layer, based on collaborative sensing that allows the opportunistic use of the electromagnetic spectrum. In this article, the operation of COLAB-5 is illustrated in a 5G environment for remote areas, which uses frequencies between 170MHZ to 700MHz and performs opportunistic access on TVWS (TV White Spaces) channels.

Keywords: network simulator, rural networks, tv whitespaces, opportunistic access
