The study on degree distribution property of complex network based on cooperative communication

Abstract

Complex networks have been widely studied. Recently, many results show that the degree distributions of some large networks follow the form of power-law and these networks possess better robustness against random nodes failure. As an effective technology on combating the channel fading, wireless cooperative communication is becoming one of the most important methods to improve the wireless communication performances. In this paper, the complex network models based on cooperative communication and non-cooperative communication are established; and the degree distribution properties for them are studied. The simulation results show that the degree distributions of these networks also follow the form of power-law, which means that the addition of cooperative communication links will not change the property of degree distribution and then these networks will possess better robustness against random nodes failure as well.
