Accurate cyber-physical system simulation for distributed visual search applications

A Cyber-Physical System (CPS) is defined as a, usually distributed, system that links the digital (cyber) and physical world. They feature different computational cores and heterogeneous sensors linked through networks of different types allowing a deeper interaction with the physical world, collecting, storing and exchanging information intelligently. In this work, an open source CPS simulator called COSSIM is described and a smart mechanism is proposed in order to turn it into a co-simulator. In addition to this, a CPS based on a Computer Vision application, called Mobile Visual Search (MVS), is described and ported to COSSIM in order to test the correctness of the simulation and to prove the benefit of the proposed acceleration. Quantitative and qualitative precision results in both real and simulated scenarios are also presented.
