Efficient Simulation of distributed Sensing and Control Environments

International audienceThe rise of the Internet of Things raises many challenges among which is the ability to efficiently simulate a real 3D environment with intelligent objects able to sense and act. Furthermore, the apparition of micro-objects able to communicate forces such as a simulator to scale up in the number of simulated nodes. In this paper, we report the progresses made in the design of a new kind of simulator named VisibleSim. VisibleSim mixes a discrete-event core simulator with discrete-time functionnalities in the most efficient way so that simulations can scale up in numbers. Experiments show that VisibleSim can accurately and smoothly simulate 2 millions of nodes at a rate of 650k events/sec on a simple laptop
