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.
