Nex-G Innovations

The objective of the NS3 Simulation Training program is to provide participants with a comprehensive understanding of network simulation and performance analysis using the NS3 platform. The program focuses on building and simulating wired, wireless, and IoT network models, enabling participants to design, test, and optimize network protocols and applications.

Through hands-on exercises, attendees will gain practical experience in configuring simulation environments, analyzing results, and applying these insights to real-world networking scenarios. By the end of the training, participants will be equipped to use NS3 effectively for academic research, development, and professional projects.
