Description
Summary:► Experimental network synchronization of Chua’s circuits is obtained. ► Network synchronization is obtained by invoking recent results from complex systems theory. ► Synchronization among a master circuit with multiple slave circuits is achieved via plastic optical fiber. ► An application to secure network communications of analogical signal and image messages is given. ► Experimental network synchronization and communication is realized by using opto-electronics devices. In this paper, network synchronization of coupled Chua’s circuits in star configuration is experimentally studied. In particular, plastic optical fiber (POF) is used in the network like communication channels among chaotic nodes to achieve synchronization. The master signal is sent to multiple slaves through a fiber optical coupler with corresponding electrical/optical and optical/electrical stages. An application to encrypted chaotic communication to transmit analogical signal and image messages to multiple receivers is also given.
