Customer Spotlight: Sastra University Leverages NetSim for Research on Securing Femtocells Identify and mitigate a possible attack in femtocells where locational information about a femtocell user is disclosed. (Research paper available in www.tetcos.com)

Challenge1. Developing the Multihop Algorithm for privacy2. Simulating and Analyzing the algorithm Use CaseDeveloping custom code: Source C files, Cellular.c, GSM.c, Handover.c and GSM_Channel.c of NetSim’s GSM library were modified. These codes were linked and debugged using NetSim’s project work environment.3. Modeling network configurations4. Generating performance metrics

ResultThe algorithm trade off was increased delay. The study found this to be approx 50 ms, which could be afforded by the network architecture.

“We chose NetSim given its extensive R & D capabilities in WSN, MANET and CR Networks. NetSim has an easy to use UI for creating scenarios, modeling protocol and device parameters. The protocol library source codes are written in C and easily understandable. NetSim’s product features and quick support from their technical team is playing an important role in our research publications”

Dr.V.S. Shankar Sriram

“NetSim is truly a fantastic product that is not only versatile, it is also robust and those features are hard to come by in any simulator. I hope other educational institutions begin incorporating this product into their curriculum.”

Nikki Warren,Project Director, Technical Education College, Ontarget Enterprises, Colorado, USA
