End-to-End Analysis of Wireless and Internet Video Streaming?

Wireless and Internet video communications require an integrated approach in which the system is optimized in an end-to-end fashion. Parametric behavioral models are needed to determine the importance of the optimization of the communication system’s components without relying too much on the particular choice of how a component is realized or implemented. These models describe the external behavior of a component, and rely on theoretical or empirical evidence. Most models include a number of parameters that need to be chosen for a particular system, or – if real-time adaptations are desired – the need to be estimated dynamically. For that reason the focus of this report is on the functional form of the models, rather than on the absolute setting of constants or parameters. This document poses a video-streaming model that will serve as basis for end-to-end analysis, and it sets a first step in collecting appropriate parametric behavioral models needed for the analysis.
