QoS Performance Evaluation of IoT-based Virtual Private Network for UAV Video

Abstract

Unmanned Aerial Vehicles (UAVs) are popular and are used for surveillance and safety purposes, thus often include live video streaming. An attacker with knowledge of the flight controller's settings can intercept the camera footage/stream. A virtual private network (VPN) connection is considered as one of the solutions in preventing unauthorised interception, but with a cost. In providing end-to-end encryption connection, the VPN connection can slow the wireless connection speed and, thus, impact the real-time streaming. This article describes the implementation of the IoT-based live video streaming system with VPN and analyses the live streaming performance based on quality of service (QoS) measurements. Comparative analysis between video streaming with and without VPN is presented.
