CONFLICT IDENTIFICATION AND RESOLUTION BETWEEN HETEROGENEOUS SYSTEMS IN IOT ENVIRONMENT THROUGH RISK BASED PRIORITIZATION

Abstract

A complex IoT environment contains multiple heterogeneous IoT systems. These IoT systems contain different devices such as sensors and actuators. These devices are responsible for sensing different events and performing actions accordingly. Normally all these devices work parallelly in a single IoT environment. Thus, multiple events are generated parallelly. Conflicts may occur when two or more parallelly occurring events start overlapping each other. Existing approaches to IoT infrastructure development have not considered the management of such conflicting events. A risk-based approach to the event and response handling is therefore desired to improve the various QoS attributes of the systems more specifically safety and efficiency. We have proposed a Conflict Identification and Resolution Model through which conflicting events within an IoT environment can be identified using a Conflict Identification Matrix, and after identification of the conflicting events they can be prioritized on the bases of risk associated to the event, in such a way that the required QoS from the IoT environment is achieved. Finally, we have demonstrated the applicability of our proposed model by simulating various conflicting events scenario in an IoT based smart home environment using Node-RED.
