A design of QoS adaptation and mixer algorithms for wireless multimedia communications

Abstract

The convergence of wireless systeins with Inultiinedia services is the challenge of future-generation wireless network. Quality of Service (QoS) provision to support distributed, real-time multin1edia applications for mobile users hasetnerged as an area of Jnajor te-chnological focus.In this work,. we propose new adaptation procedures to provide desired QoS in wireless networks which allow the system to recover automatically, if possible from 1 QoS violations by identifying a new configuration of system units that might support the initially agreed QoS and by performing a user transparent transition from the origina1 configuration to the new one. We also propose mixer algorithms that can be used in bad atmospheric conditions during heavydata loss due to data loss due to wireless problems.
