Quality of Service (QoS) in Internet of Things

The Internet of Things (IoT) has emerged with an ultimate goal of automating human life by providing its services. This incredible technology has a huge potential by which it can make human life simpler and easier. To increase the popularity of any type of services, first, their quality metrics need to be defined clearly. In IoT also, Quality of Service (QoS) metrics are needed to be defined first then only user will be able to understand and express their requirement using these metrics. This work is a step in this direction. This work identifies and describes various QoS metrics of IoT keeping the fact in mind that Computing, Communication and Things are three pillars of IoT. This work helps IoT providers to describe their services, users to describe their needs and researchers and professionals to develop the models in IoT considering the importance of QoS metrics.
