DEVS-Based IoT Management System for Modeling and Exploring Smart Home Devices

Smart home management systems are essential for smart buildings and cities. The heterogeneity of smart devices in terms of performance, heating behaviors, and energy consumption can result in different patterns of smart home behaviors and measurements. This paper proposes a modeling and simulation approach using Discrete Event System Specification (DEVS) formalism to simulate the behaviors in terms of power usage and cost in smart home devices under different scenarios and settings. Smart devices are divided into two categories: monitoring devices and control devices. Monitoring devices include sensors that capture data of climate, energy, electrical power usage, performance, and occupants' behavior. Control devices are used to send signals for setting and remote controlling of the different devices in the smart home. The result of this work enables designers to provide key solutions such as automatic control and monitoring of the power consumption, electrical load, and heating behaviors. It also helps system designers to make correct decisions in setting up the appropriate number of devices and types, while testing the system performance beforehand under different conditions, parameters, and scenarios.
