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”
