A chaotic wireless communication system based on collective synchronization among wireless nodes

Abstract

A chaotic wireless communication system is described that is based on collective synchronization among wireless nodes. Chaotic synchronization was first investigated by numerically analyzing the collective behavior of wireless nodes, each having Chua's circuit as a chaos generator. The condition required to achieve synchronization among three nodes was estimated using numerical analysis. Numerical simulation demonstrated the possibility of chaotic synchronization among many wireless nodes and the possibility of formation of node clusters through chaotic synchronization. This study will open new research areas for chaotic communications and complex networks. © IEICE 2006.
