Mathematical models for radio channel usage evaluation when transmitting real-time flows through wireless self-organizing networks

The wireless self-organizing network eff ectiveness is considered in terms of radio channel utilization. The uneven receipt of real-time streaming requests to the network leads to ineffi cient radio channel usage, which in turn leads to a decrease in the streaming quality over the network. To increase radio channel utilization, it is proposed to use buff ering for smoothing the incoming audio and video transmission requests fl ow. In the article, the defi nition of the radio channel utilization rate is given. Mathematical models are presented for assessing radio channel utilization when transmitting realtime streams in a wireless self-organizing network. The results of computational experiments on estimating the radio channel average performance with and without buff ering are shown. The fi ndings prove that it is possible to signifi cantly increase radio channel utilization by using the real-time streams transmission requests buff ering.
