Control information flow with transformation in complex networks

It is a typical inverse problem to design the global states by controlling or adjusting the local dynamic characteristics. This paper introduces an information flow mechanism, and analyses the distribution characteristics of the information flow in global networks. The space transformation method, which is originally used to control the physical field by designing material parameters, is proposed to obtain necessary local dynamic parameters when the global state of a network is prescribed in a space. With this method, the area of key and essential nodes in the network is cloaked by adjusting the route of information flow spread. Finally, the simulations show that the method is a intuitive and direct way for network control.
