Leadership
Pranav Viswanathan
Co-Founder and CEO
Pranav is the co-founder of NetSim (2005) and its chief architect. As CEO, he oversees R&D, Product and Support. His expertise is the simulation of 5G/6G networks, Wi-Fi, Mobile Ad Hoc Networks (MANETs), military radios and the Internet of Things (IoT). His current focus areas are AI/ML in the RAN, Non-Terrestrial Networking, Network Slicing and MANET military radio networks.
He enjoys working with customers, understanding their requirements and meeting their needs with software. He has 20 years of experience in the modeling and simulation of wireless networks, and he travelled worldwide to build solutions with NetSim. Pranav received his B-Tech from IIT Madras in 2003.
Shashikant Suman
Co-Founder and Technical Lead
Shashikant is part of the founding team of NetSim and is the current development lead.
Over the years, he developed most of the internal infrastructure of NetSim: the virtual (TCP/IP) network stack, the emulator module for external connectivity, the NetSim APIs and the custom code development framework. He also wrote a number of protocol libraries, including 802.11, 802.15.4, MANET, VANET and 5G NR.
His present work is on the 5G/6G library, to meet the needs of cellular service providers, and on new visualizations in the GUI. Shashikant received his
Integrated MSc from IIT Kharagpur.
Scientific advisory
These academics review our models and results independently.
Prof. Anurag Kumar
Indian Institute of Science, Bangalore. Since 2005
He reviews the scientific correctness of the networking protocol implementations in NetSim. He also advises on algorithm selection and on the interpretation of simulation outputs.
Prof. Chandra R. Murthy
Indian Institute of Science, Bangalore. Since 2018
He reviews the PHY layer including our MIMO, beamforming, channel and propagation
models, and link adaptation, together with the results derived from them.
