Analytical model of a P-persistent method of queue management for multimedia streaming over wireless networks

摘要

On the transmission of several streams to different recipients over a wireless network in the case of degradation of the link quality with any of them, the head-of-line-blocking problem arises. This problem is especially important in the case of streaming with strict requirements to the quality of service. One of promising solution of this problem is the use of the P-persistent policy of queue management. In this work, an analytical model of such policy is proposed, making it possible to confirm the efficiency of this policy for preventing the head-of-line blocking and find the optimal values of its parameters.
