mperf & 5G Research

Mobile Network Research at MSSN Lab

Role: Research Assistant
Advisor: Chunyi Peng, Professor, Purdue University

mperf Platform

• Independently developed the initial mperf platform using Django and Android for remote experiment control and automated cellular-network measurements
• Collected 705 hours of data comprising 4.6 million throughput samples across three U.S. carriers, supporting two published studies

MMMap

• Redesigned the database and visualization workflows of MMMap for 32,000+ network cells and 18,700+ handoff events, achieving a 10× speedup in data analysis and display

Protocol Security Analysis

• Applied lightweight formal analysis to 3GPP Release 17 IoT protocols
• Identified four vulnerabilities and developed 12 proof-of-concept demonstrations

Cellular Measurement Studies

• Collected and analyzed 45 hours of UAV network measurements over 1,010 km, using radio-access-network traces to compare airborne and ground-level throughput, latency, and mobility failures
