Cálculo Eficiente da Distribuição do Tamanho de Filas baseado em Modelos de Fluido

Ana Paula Couto da SilvaRosa Maria Meri LeãoEdmundo de Souza e Silva

Multimedia networks have been extensively studied in the literature. Markovian reward models have been used to model and to obtain performance measures from multimedia networks. In these models, reward rates are associated with states and/or reward impulses are attributed to transitions between states. We have developed an algorithm to obtain the queue size distribution of a finite buffer when it is fed by a fluid. We base our analysis on impulse reward models. The probability transition matrix generated from the model we obtained has a special structure that is the key to our technique. The algorithm presents computational advantages when compared with others approaches in the literature.
