Long-range dependence in WiMAX traffic. A preliminary analysis

Last years, long-range dependence (LRD) has become a key concept in analyzing the traffic in a telecommunication network. The aim of this paper is to analyze the downlink traffic in a WiMAX network in terms of LRD. For the estimation of Hurst parameter we adopted the Rescaled Adjusted Range Method (R/S). We have obtained estimated values for each downlink trace from the data base which correspond at the considered network. Some particularities of the network can be established analyzing these values. Rules for the optimization of the network´s exploitation can be derived analyzing these particularities.
