Quality aware protocol to support multimedia data delivery in wireless network

Transmission of multimedia application over wireless network poses multiple challenges. For supporting the multimedia application currently the use of cross layer architectures and Scalable Video Coding (SVC) techniques are considered. The current architectures fail to maintain the relationship that exists between the end to end delay and the Quality of Service (QoS) provisioning of the video data to be delivered. To address this issue this paper introduces the QoS improvement scheme in video transmission model based on a cross layer architecture. A novel MAC encoding of the SVC video is considered in the proposed model. Based on the physical layer conditions and the QoS achievable the model adapts to meet the stringent delay requirements of video delivery. Routing layer optimization is achieved by accounting for the pending packets queues in every neighboring node, uses of adaptable physical layer knowledge specifier author reduce the distortion. Through the experiment it shows that purposed model is better by comparing existing model in terms of quality of reconstruction, transmission error rates.
