Nex-G Innovations

The objective of the NS2 Training program is to provide participants with a thorough understanding of network simulation techniques using the NS2 platform. The program focuses on simulating and analyzing the performance of wired, wireless, and sensor networks.

Participants will gain hands-on experience in protocol modeling, traffic analysis, and performance optimization. By the end of the training, attendees will be proficient in using NS2 for academic research and professional projects, enabling them to design and evaluate complex network systems effectively.
