Requirement-based prioritization system in multi-user IoT

In this paper, a problem of sending a large amount of sensor data from a gateway to a faraway server over limited resources in multi-user IoT system has been studied. We propose a sensor data prioritization approach based on user requirements for maximizing the satisfaction value. The approach utilizes an MCDA (Multi Criteria Decision Analysis) technique called REMBRANDT to aggregate requirements and to determine a single priority value over sensor data with different attributes. Through a building management system case study, we have shown that our method can obtain higher satisfaction than naive transmission strategies in practical situations.
