A Holistic SDN-Capable Session-Plane Tailored for Efficient IoMT Smart Surveillance Applications

The Internet of Multimedia Things (IoMT) is aimed at supporting innovative Smart Surveillance applications, such as intelligent transportation, smart health, smart grid, and public security, among others, in the Future Internet. These applications explore ultimate techniques to collect and process a large amount of video/audio data generated by billions of devices, such as cameras, smartphones, microphones and home appliances, in the Internet of Everything (IoE). However, typical networking solutions based on unicast/IP multicast are limited, in terms of performance and scalability, to Smart Surveillance in large-scale IoMT environments. We address these limitations by proposing SCORPIO, an SDN COntRol Plane which provides efficient multipart multimedia data sessions for Smart Surveillance applications in the Future Internet. SCORPIO exploits OpenFlow to dynamically map a multipart session into a group-based dataplane path for content exchange between multiple interested applications and groups of IoMT devices. Evaluations of SCORPIO in scenarios with Smart Surveillance traffic show its superior throughput, and lower packet loss and delay.
