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)
Challenge
Result
The algorithm trade off was increased delay. The study found this to be
1. Developing the Multihop Algorithm for privacy
approx 50 ms, which could be afforded by the network architecture.
2. Simulating and Analyzing the algorithm
Use Case
Developing 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 configurations
4. Generating performance metrics
“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”
