Abstract

This paper discusses long-range dependence (self-similarity) in cellular network traffic, which is a phenomenon of complex systems. Assuming three kinds of cellular systems such as FCA-TDMA, DCA-TDMA and CDMA systems, we analyze the traffic intensity of the three systems by computer simulation. Our simulation results show that long-range dependence appears in DCA-TDMA system, and its cause is quite different from that of wired networks. Then, we propose a method for suppressing the long-range dependence which has a bad influence on the system performance, and show that the proposed method can effectively suppress the long-range dependence.
