Improving WLAN QoS for multimedia application using MAC and application layer (MAP) approach

Quality of Service (QoS) is considered as the standard check of a conveyance system to show provided services and its availability. For illustration application like video conferencing, voice over ip (VOIP), streaming videos, real time operation feel necessity for draconian assurance on jitter, packet loss, prioritization of services and end-to-end delay. So to overcome these issues a novel scheme employing MAC and Application Layer protocols with enhanced (MAP) is proposed. Improved black-burst protocol as well as prioritization of services is proposed at the MAC layer. An influential packet scheduling scheme for multimedia application in IEEE 802.11e has also been designed. At the Application layer level, real time protocols such as Session Description Protocol (SDP) and Real Time Streaming Protocol (RTSP) are adopted to support QoS. The performance of proposed MAP with enhanced Black Burst Protocol is studied with OPNET 14.5 simulator. The result shows that proposed MAP mechanism has better performance in QoS parameters considered, while maintaining fairness during channel allocation.
