“…Related work in the literature can be divided into three main categories: (i) the studies of tools for estimating available bandwidth of an end-to-end path at a particular point in time [16,18,24,25,32,34], (ii) the studies of a suitable model for aggregate available bandwidth across sufficiently large numbers of paths [17], and (iii) the studies of suitable models for network traffic [3,5,6,9,14,[26][27][28][29].…”

“…The result of this recent work implies nothing about the behavior of the available bandwidth of a single path over time, which is the focus of our study. Lastly, the related work [2,3,5,6,9,14,[26][27][28][29] studied modeling and characteristics of the amount of transmission bandwidth consumed by both overall network traffic and some major network traffic types, for example FTP, TELNET, HTTP, and variable-bit-rate (VBR) videos. This existing work and ours are different since we focus on modeling of the available bandwidth of a path, not a particular type of traffic or the overall network traffic.…”

“…The results of the related work [3,5,6,9] could be used to imply the model of available bandwidth over time of a path. However, they are controversial.…”

“…The related work [3] reported that most of the traffic traces considered in their analysis can be modeled as ARIMA processes. On the other hand, the results of the related work [5,6,9] indicated that it was possible to model the transmission bandwidth consumed by a variety of network traffic as self-similar processes. Therefore, we believe that it is still crucial to particulary conduct a study of modeling of the available bandwidth of an end-to-end path over time.…”

This article presents a very simple model based on gamma functions for MPEG1 and MPEG2 VBR digital video. This model is a simplification of Frey's et al model.It captures first grade statistics and the cyclicity of the autocorrelation function. Buffer overflow losses with the proposed model are of the same magnitude that buffer overflow losses of the original video clips. We have found three zones in the buffer overflow losses under certain conditions. Zone number two is of special interest because identified losses are produced by extraordinary large frames.

To optimize performance of applications running over wireless channels state-of-the-art wireless access technologies incorporate a number of channel adaptation mechanisms. While these mechanisms are expected to operate jointly providing the best possible performance for current wireless channel and traffic conditions, their joint effect is often difficult to predict. To control functionality of various channel adaptation mechanisms a new cross-layer performance optimization system is sought. This system should be responsible for exchange of control informationbetween different layers and further optimization of wireless channel performance. In this paper design of the cross-layer performance control system for wireless access technologies with dynamic adaptation of protocol parameters at different layers of the protocol stack is proposed. Functionalities of components of the system are isolated and described in detail. To determine the range of protocol parameters providing the best possible performance for a wide range of channel and arrival statistics the proposed system is analytically analyzed. Particularly, probability distribution functions of the number of lost frames and delay of a frame as functions of first- and second-order wireless channel and arrival statistics, automatic repeat request, forward error correction functionality, protocol data unit size at different layers are derived. Numerical examples illustrating performance of the whole system and its elements are provided. Obtainedresults demonstrate that the proposed system provide significant performance gains compared to static configuration of protocols.
