Virtual Development of a Presence Sensor Network Using 3D Simulations
Testing the control and deployment of large networks of sensors and actuators is a complex and expensive task. This paper presents a 3D simulation tool that facilitates testing and measuring this kind of systems in a virtual environment, which alleviates the costs of doing these tasks in a physical setting. This is illustrated with an example of how a presence detection system can be designed to monitor the behavior of a crowd under different stimulus. The simulation does not only involve the devices, but provide input data so that they can be decoupled and analyzed separately. This decoupling allows to experiment with different deployments of sensors while the simulation is still working and evaluate their performance in real time. Such feature can be of assistance for decision making when designing a large installation or improving one. The paper contributes with a proof of concept where a large installation, together with its inhabitants, is simulated. The simulation is used then to create different simulations of photoelectric devices that register the proximity of an individual. The results permit to evaluate networks of such devices and think of different configurations without the limitations of the physical environment and the privacy and integrity concerns of individuals.
