Optimal Queue Sizing for Traffic Management of Mixed Mobile Traffic in Wireless Network

Abstract

Nowadays, wireless networks which offer various multimedia services to mobile users are demanding Quality of Services (QoS) for these services. Therefore, defining optimal queue size of various mixed applications at an Access Point (AP) not only plays a key role for resource scheduling and QoS of mixed applications and but also is a challenging problem in 802.11 Wireless networks. Due to the fact that queue size impacts on throughput and delay of mixed multimedia applications in congested network, the main objective of this paper is to provide an optimal queue sizing mechanism which maintain high link utilization efficiently and give low queuing delays in wireless networks. The optimal queue sizing method which is based on router buffer sizing methods such as QFind and Rule of Thumb methods is proposed by testing and analyzing the performance of users at an AP with various numbers of queues according to previous proposed papers.
