摘　　要：Internet of Things （IoT） applications such as environmental monitoring, healthcare, surveillance, event recognition and traffic con- trol are amongst the most commonly deployed applications over the Interact. These applications involve multimedia content that has to be collected, processed and delivered appropriately over the Interact for further processing by human or machines. These applications come with their own set of requirements such as quality, computational power and bandwidth. It is, therefore, vital to minimize power consumption and bandwidth usage in loT devices without compromising the quality of multimedia delivery. Since the delivery of the multimedia can be destined to a machine or human, it is important to distinguish multimedia quality between the two, Quality of Experience （QoE） for video services involves human visual system, but what will involve a machine or process？ To distinguish between the two, this paper defines a new concept of Acceptable Quality of Things （AQoT） which involves lot devices and their applications. AQoT aims at minimizing bandwidth without compromising quality in loT devices, Experimental re- suits based on human detection and license number plate detection use eases have demonstrated that the AQoT concept can sig- nificantly reduce bandwidth usage.Internet of Things （IoT） applications such as environmental monitoring, healthcare, surveillance, event recognition and traffic con- trol are amongst the most commonly deployed applications over the Interact.
