Abstract
We present WiFiMon, a lightweight active monitoring open source system for Wi-Fi network performance evaluation and verification. Using an objective Quality of Experience (QoE) assessment approach, WiFiMon is capable of capturing Wi-Fi throughput as experienced by end users without requiring their intervention. This is possible via crowdsourced measurements that are automatically triggered when the end users visit websites preconfigured with WiFiMon technology. Crowdsourced results are combined with probe measurements collected from small form factor devices located at fixed points within the monitored network; this enables Wi-Fi administrators to reach stronger conclusions about the performance of their networks. When deployed in IEEE 802.1X networks, WiFiMon provides additional benefits, e.g. fine-grained performance analysis per access point, by integrating data from available RADIUS and DHCP logs, which are correlated with the crowdsourced and probe measurements. Our system capabilities are demonstrated based on WiFiMon pilots, which took place in recent events with several hundreds of participants (TNC19 Conference, GEANT Symposium 2020). We conclude that WiFiMon can effectively detect Wi-Fi performance fluctuations.
