IEEE 802.11 Wireless LAN, popularly known as
WiFi, has become the admired source of internet connectivity for
most of the offices as well as organizations. Due to the rapid
growth of multimedia data and VoIP and also to provide better
quality of service (QoS), bandwidth and management of
bandwidth have become important factors in 802.11 wireless
LAN. In 802.11 wireless LAN, Enhanced Distributed
Coordination Access (EDCA) mechanism provides QoS with
service differentiation by setting different priority to different
traffic types. Some of the available methods provide priority
based on user category also. In this paper we have proposed an
intelligent bandwidth management technique based on the user
priority value, traffic priority value and the bandwidth
requirement value. By combining these three values, a new
metric called request weight value is calculated. Based on this
request weight value, dynamically bandwidth is allocated to the
users. From the simulation results, we have seen that the
proposed method performs well in proper utilization of bandwidth
among the available users.
