摘要：Internet of Things applications such as environmental monitoring and healthcare may involve multimedia
communications from IoT devices to humans for decision-making. Therefore, the quality of delivered
multimedia should be in good perceived quality. Higher video quality results into higher energy
consumptions due to encoding and decoding processes and as a result, will affect the performance of IoT
devices due to their inherent energy constraints. This paper presents the impact of video encoding
parameters as non-network parameters on the energy consumption of IoT devices. The experimental results
from Cooja simulator show that the videos with high bitrates and low frame rates consume more power
than videos with low bitrates and high frame rates. It was also found that video content type affects energy
consumption. Finally, this paper proposes a power model that takes into account video parameters such as
bit rate, frame rate and content types. The proposed model can play a vital role in video quality adaptation
in multimedia communication over IoT devices.
