Data Sharing Strategy for Guaranteeing Quality-of-Service in VoD Application

The phenomenal growth in the distributed multimedia applications has accelerated the popularity of Video-on-Demand (VoD) system. The vital task of multimedia applications is to satisfy diverse client´s request for distinct video with confined resources by using assorted Quality-of-Service (QoS) procedures. In this paper a fusion of data sharing techniques like batching and recursive patching is applied in the local server for ensuring Quality-of-Service to the clients and enabling higher throughput. The network resources are apportioned appropriately using batching and the time difference between the requests is minified by recursive patching. The suggested algorithm renders the entire video to the clients using true VoD, near VoD using multicast or broadcast scheme depending on popularity of the video. The experimental results indicate that our approach accomplishes 2% reduction in blocking ratio and throughput is 10% -15% greater than the Poon ´s strategy [15], which depicts that not only the resources are efficiently utilized but also a suitable Quality-of-Service is provided to each client.
