In Industry 4.0, the information comes from a manufacturing network is monitored and coordinated under the cyber-physical system. Wireless sensor networks are deployed to collect the massive amounts of data generated in a manufacturing network. Sensor cloud is employed to facilitate the management of a large number of wireless sensor nodes. Facing with concurrent sensing demands of users, administrators of a manufacturing network needs to deal with the management of virtual sensors. We propose a novel virtual sensor management scheme which is able to give an overall virtual sensor instantiation result for the whole manufacturing network. Both the architecture of the manufacturing network and the application scenario are modeled by entities and actions. Moreover, we developed two resource scheduling algorithms to approach the problem of virtual sensor management. A detailed analysis is provided based on extensive simulations.
