In this paper it presents, develops and discusses the existence of a process with long scope
memory structure, representing of the independence between the degree of randomness of …

In this paper it presents, develops and discusses a new and simple algorithm based on the
local maximum likelihood estimator of Whittle, for the estimation of the Hurst exponent of …

Conventional video traces (which characterize the video encoding frame sizes in bits and
frame quality in PSNR) are limited to evaluating loss-free video transmission. To evaluate …

As the demand for broadband multimedia wireless services is increasing, improving quality
of service (QoS) of the widely deployed IEEE 802.11 wireless LANs (WLANs) has become …

An extension of the models used to generate fractal traffic flows is presented by means of the
formulation of a model that considers the use of one-dimensional chaotic maps. Based on …

Study of high speed networks such as optical next generation burst or packet switched
networks require large amounts of synthetic traffic to feed simulators. Methods to generate …

Statistical self-similarity of random processes in continuous-domains is defined through
invariance of their statistics to time or spatial scaling. In discrete-time, scaling by an arbitrary …

Heavy traffic models for wireless queueing systems under short range dependence and light
tail assumptions on the data traffic have been studied recently. We outline one such model …

High-speed wireless networks carrying multimedia applications are becoming a reality and
the transmitted data exhibit long range dependence and heavy-tailed properties. We …

This paper presents an extension of the models used to generation fractal traffic flows in
high-speed computer networks by means of the formulation of a model that considers the …
