QoE-based Performance Evaluation of Video Transmission using RPL in the IoMT

Internet of Things systems can not successfully realise the notion of ubiquitous connectivity of everything if they are not capable to truly include multimedia things. In this paper, we investigate the feasibility of video streaming using RPL (Routing Protocol for Low Power and Lossy Networks) by focusing on the impact of radio duty cycling on the quality of received video and the energy footprint of the network. To do so, we adopt a low complexity compression technique and use Cooja simulator to carry out our experiments. We use quality of service (QoS) as well as quality of experience (QoE) metrics to evaluate the quality of the received video. We mainly show that RPL along with ContikiMAC, the Contiki default radio duty cycling do not allow to handle real time video transmission in the context of constrained networks. However low rates up to 35 frames per minute are still possible with an acceptable quality.
