Video Processing on the Edge for Multimedia IoT Systems
It addresses efficient video processing on edge devices for multimedia IoT applications, but is incremental as it builds on existing virtualization technologies.
The paper surveys edge video processing for multimedia IoT systems in smart cities, satellite networks, and Internet-of-Vehicles, proposing a cooperative method based on lightweight virtualization and evaluating its performance.
In this article, we first survey the current situation of video processing on the edge for multimedia Internet-of-Things (M-IoT) systems in three typical scenarios, i.e., smart cities, satellite networks, and Internet-of-Vehicles. By summarizing a general model of the edge video processing, the importance of developing an edge computing platform is highlighted. Then, we give a method of implementing cooperative video processing on an edge computing platform based on light-weighted virtualization technologies. Performance evaluation is conducted and some insightful observations can be obtained. Moreover, we summarize challenges and opportunities of realizing effective edge video processing for M-IoT systems.
