Interoperation of distributed mcu emulator/simulator for operating power simulation of large-scale internet of event-driven control things

Abstract

Internet of Event-Driven Control Things (IoEVCT), the large-scale event-based control systems based on the Internet-of-Things (IoT) can be composed of a series of sensors, controllers, and actuators. It is wirelessly connected by the internet of events between sensors and actuators. The perceptible objects are considered as not only a time-based, controlled system at the micro level, but also as an event-driven, controlled system at the macro level of large-scale IoT. This paper introduces our initial effort to implement a newly designed simulation framework for quantitative power measurement when a large number of sensors and actuators are connected wirelessly to control certain plants. Power consumption of the whole system can be divided into power consumed by a microcontroller unit (MCU) in sensors and actuators. Using the proposed architecture, we can range from the low-level viewed power via an MCU to the whole power of the large scale of control things. We try to substitute each physical MCU in the sensor and actuator devices with the emulation based on an instruction set simulator (ISS) to reduce the physical cost caused by experiments in real environment. Using the proposed simulation framework, our study shows a possibility that the sensing, controlling, and actuating process in the wirelessly connected control systems over the large-scale IoT can be analyzed in terms of the power consumption, which is affected by various environmental causes around IoT.
