Real Time Wireless Packet Monitoring with Raspberry Pi Sniffer

This paper proposes a real time wireless packet monitoring system using a Raspberry Pi. The system is a low cost alternative to commercial packet capture devices and analysis software. In our solution, captured packets from sniffer are sent to main server to gather statistics. Packets are analyzed and only the relevant data are stored in database. A notification server developed in Node.js provides communication between database and user interface developed with Django web framework. The performance of the proposed solution is successfully evaluated in an environment with multiple wireless networks. Results are presented.
