Evaluating a Digital Twin of an IoT Resource Slice: An Emulation Study using the ELIoT Platform

This paper proposes a realistic setup for a digital twin of an IoT deployment, which makes it possible to measure the impact of IoT networking and computing slices on the physical resources of edge computing hosts. The proposed setup relies on a configurable IoT system, capable of emulating the behavior of a LWM2M broker, along with a large number of devices, both real and emulated. Through our digital twin, we can measure IoT resource utilization and its variation over time, quantifying utilization peaks that may occur at transients, when devices attach to or leave the network.
