Topology-Aware Low-Cost Video Streaming for Video Data Over Heterogeneous Network

Abstract

The wireless security surveillance system is one of the widely implemented applications of the Internet of things technology. These systems, enabled with security cameras, are connected to the Internet and provide complete security access to critical infrastructure. Recently, the usage of unmanned aerial vehicles for surveillance, especially in defense setups and areas beyond physical reach, is on the rise. These systems feed the base station with continuous video stream content and therefore need strong network support for meeting the set performance requirements. It can be achieved by offering better network streaming capabilities to the base station. In this paper, we address the problem of streaming over a network of UAV systems that are designed to handle video stream content by providing a cost-effective path to base station. Contrary to a lot of existing works in this direction, we do not rely on GPS information to select streaming routes. We use topology information and a graph-theoretic approach to select paths. The proposed streaming route selection mechanism is shown to be more stable, preserves the quality of video data, and is energy efficient compared to other related schemes.
