In an Internet of Things (IoT) environment, the existence of a huge number of heterogeneous devices, which are potentially resource-constrained and/or mobile has led to quality of service (QoS) concerns. Quality approaches have been proposed at various layers of the loT architecture and take into consideration a number of different QoS factors. This paper evaluates the current state of the art of proposed QoS approaches in the loT, specifically: (1) What layers of the loT architecture have had the most research on QoS? (2) What quality factors do the quality approaches take into account when measuring performance? (3) What types of research have been conducted in this area? We have conducted a systematic mapping using a number of automated searches from the most relevant academic databases to address these questions. This mapping has identified a number of state of the art approaches which provides a good reference for researchers. The paper also identifies a number of gaps in the research literature at specific layers of the IoT architecture. It identifies which quality factors, research and contribution facets have been underutilised in the state of the art. (C) 2017 Elsevier Inc. All rights reserved.
