Transmission algorithm for video streaming over cellular networks

2.5G and 3G cellular networks are becoming more and more widespread. Therefore, the need for value added services is increasing rapidly. One of the key services that operators seek to provide is streaming of rich multimedia content. However, the network characteristics are making the use of streaming applications very difficult with an unacceptable QoS. The 3GPP standardization body has standardized streaming services. A standard solution for multimedia streaming will benefit operators and users. There is a demand for a mechanism that will enable a good quality multimedia streaming using 3GPP standard. This paper describes an adaptive streaming algorithm using 3GPP standard that improves significantly the quality of service in varying network conditions and monitors its performance using queueing methodologies. The algorithm utilizes the available buffers on the way of the streaming data in a unique way that guarantees high QoS. The system is analytically modeled: the streaming ser...
