In order to ensure that such services provide their functionalities with the expected quality, it is essential to measure and evaluate this quality, which can be in some cases a challenging task due to the lack of human intervention and feedback. Recently, the vast majority of the Quality of Experience QoE works mainly address the multimedia services. However, the introduction of Internet of Things IoT has brought a new level of complexity into the field of QoE evaluation. With the emerging of the new IoT technologies such as machine to machine communication and artificial intelligence, there is a crucial demand to utilize additional evaluation metrics alongside the traditional subjective and objective human factors and network quality factors. In this systematic review, a comprehensive survey of the QoE evaluation in IoT is presented. It reviews the existing quality of experience definitions, influencing factors, metrics, and models. The review is concluded by identifying the current gaps in the literature and suggested some future research directions accordingly.
