A Comparative Study and Survey on Broadcasting Multimedia Streaming Data Congestion Control Mechanisms?

The real time transferring data of multimedia content (Multimedia streaming) come to be a projecting field with the advance of different networking technology and multimedia streaming technology. Most of the broadcasting applications such as video conferencing, Face-time, Daily-motion, Mobile video calling, Webinar, visual telephone, YouTube have become more and more popular etc. need multimedia communication techniques that send multimedia data from one end to another with enhanced productivity, strength and security. Multimedia broadcasting streaming service requires adequate bandwidth and delay dissimilarity to attain outstanding quality of service. Congestion occurs frequently owing to random fluctuations and burstiness of traffic flows within high speed networks. Congestion has to be resolved as it is the main cause for packet loss and long delay that affects the Quality of Service in the Networks. A number of researchers over last decade developed a number of congestion control mechanisms. But Congestion control for streamed media data traffic over Internet is still a great challenge. This paper presents A Comparative study, survey and points out Pros and Cons of various congestion control protocols and algorithms that were developed to suit media broadcasting traffic over Adhoc networks or internet.
