Demo - DingNet - A Simulator for Large-Scale IoT Systems with Mobile Devices.

The Internet-of-Things (IoT) provides an enabling layer for smart cities. However, engineering such large-scale IoT deployments is challenging since these systems typically consist of complex distributed infrastructure of gateways and devices. To investigate and test IoT solutions before deployment in the field, engineers can make use of simulation. In our research, we study large-scale IoT systems for smart city applications that comprise of mobile devices that sense parameters of the environment and send the sensor data to a user application via stationary gateways. As existing IoT simulators are not sufficient to support our research, we developed a novel simulator of DingNet, an IoT system that is deployed in Leuven. In this paper, we give an overview of the simulator design and we illustrate how we used for the study of an IoT scenario with multiple mobile devices.
