Modeling of real-time multimedia streaming with deterministic access

To provide Quality of service (QoS) in wireless networks, deterministic channel access is often used. The key idea of the method is to provide a prerogative to a station to access the channel during allocated time intervals called reservations. The existed protocol standards define how to set up a reservation but do not describe how many reservations should be allocated to meet QoS requirements. This challenging issue is complicated in case of a real-time multimedia stream of variable bitrate. To address this issue, in the paper, we propose an algorithm of dynamic resource allocation for the stream in the presence of noise.
