(DEMO) WTTool: A Visual Web-based Topology Generator and 5G Network Simulator with ns-3

In this work, we provide a web-based application designed to aid researchers in the study of wireless network performance. This application provides several key features. The graphical user interface allows users to create realistic topologies through the use of real geographical data. Our application allows for the sharing of network topologies among researchers, improving the reproducibility of results. The network simulator, $\mathrm{ns}-3$, is built into the platform providing users with a simple, seamless method to generate realistic results. The visualization of these results as a heatmap allows users to better understand and predict the performance of their network, allowing them to change its configuration to meet specific requirements before the actual deployment. Altogether, this application contains tools for each step of wireless network research: from network design, to result generation and visualization.
