Abstract

Abstract— Network traffic monitoring plays an important role in maintaining the availability, reliability, and performance of modern network infrastructures. The increasing volume and complexity of network traffic require monitoring solutions that provide real-time visibility, traffic profiling, anomaly detection, and comprehensive usage analysis. This study proposes an AI-based Wi-Fi network traffic monitoring and analysis system that integrates ntopng for traffic collection, Python-based analytical modules, Prometheus for metrics aggregation, Grafana for visualization, K-Means Clustering for traffic profiling, and Isolation Forest for anomaly detection. The system was implemented in a wireless network environment using real network traffic data collected through the ntopng REST API. The collected traffic data were analyzed to identify traffic patterns, assess traffic severity, categorize network usage activities, and generate monitoring metrics for real-time visualization. The results demonstrate that the proposed system successfully performs traffic clustering, anomaly detection, usage categorization, dashboard-based monitoring, and automated alert integration. Furthermore, the generated analytical information provides insights into network utilization patterns that may support future Quality of Service (QoS) implementation, bandwidth allocation strategies, and intelligent network management. The integration of machine learning techniques with modern monitoring platforms contributes to more effective and centralized network monitoring.
