Improving the Multimedia traffic Performance over Wireless LAN
In order to grapple with the continuously increasing demand on the multimedia traffic over high speed wireless LAN, we need a QoS-oriented MAC for wireless multimedia system. In this thesis, we will propose a efficient centralized scheduled access MAC approach in IEEE 802.11 to satisfy multimedia traffic.There are two main algorithms to achieve the goal, queue management algorithm for downlink and uplink to satisfy video traffics high bandwidth requirement,polling list management method enhance the efficiency of the polling scheme for transmitting voice traffic. The result shows that the centralized scheduled access MAC approach we propose has excellent efficient and compelling performance.
