Uncertain Configurable IoT Composition With QoT Properties

Concerns about Quality-of-Service (QoS) have arisen in an Internet-of-Things (IoT) environment due to the presence of a large number of heterogeneous devices that may be resource-constrained or dynamic. As a result, composing IoT services has become a challenging task. At different layers of the IoT architecture, quality approaches have been proposed that take a variety of QoS factors into account. Things are not implemented with QoS or exposed as services in the IoT context. Actually, the Quality-of-Thing (QoT) model of a thing is composed of duties that are each associated with a set of non-functional properties. It is difficult to evaluate the QoT as a non-functional parameter for heterogeneous thing composition. Uncertainty emerges as a consequence of the plethora of things as well as the variety of the composition paths. In this paper, we establish a standard method for aggregating Things with uncertainty awareness while taking QoT parameters into account.
