Um Controlador Nebuloso para Adaptação de QoS

Cristian KoliverJean-Marie Farines

In this paper, we describe the implementation of a fuzzy controller which adjusts dynamically the bit rate of distributed multimedia applications. The controller, deployed in the sender's side, uses the packet loss rate of the receivers - which is obtained from RR packets of RTCP protocol - as feedback and computes the new bit rate by means of linear functions, in agreement with the Takagi-Sugeno's fuzzy controller model. In this work we also describe an approach to map the bit rate to application QoS parameters in order to allow the controller to adapt the application with regard to the computed bit rate.
