This repository contains two practical laboratory reports from the Wireless Security course held at Politecnico di Torino, 2024/2025. The labs explore vulnerabilities and performance characteristics of wireless technologies through hands-on experiments and analysis.
This lab focuses on:
- Collecting and analyzing raw GNSS measurements using Android smartphones and the GnssLogger app.
- Evaluating positioning accuracy under different environmental conditions (open sky, battery-saving mode, obstructed reception).
- Applying filters to improve positioning precision.
- Simulating GNSS spoofing attacks and analyzing their impact on positioning and receiver bias using MATLAB scripts.
Key findings:
- GNSS accuracy is significantly affected by environment and signal quality.
- Spoofing attacks can effectively mislead GNSS receivers, highlighting the need for countermeasures like anomaly detection and signal authentication.
This lab explores:
- Performance benchmarking of WiFi connections (802.11ac) using Wireshark and iperf3.
- Multiple network scenarios: WiFi-to-WiFi, Ethernet-to-WiFi, and Ethernet-to-Ethernet.
- Impact of TCP/UDP protocols, bitrate tuning, and packet length on network goodput.
- WiFi asymmetry, congestion, and bufferbloat effects on throughput and latency.
Key findings:
- Wireless links are more prone to performance variability and packet loss compared to wired ones.
- Careful tuning of parameters (e.g., UDP bitrate and packet size) can significantly improve performance.
- TCP performance is affected by network congestion, leading to ACK delays and reduced throughput.
