Research of Congestion Control in Wireless Video Transmission

With the development of the wireless communications technology and the multimedia technology, the wireless internet multimedia transport of real-time becomes an important applications field. We will meet a problem that the distinguish of the status of package loss is not very good which will affect the QoS when we transport multimedia data in wireless internet. Based on this problem the article comes up with a new algorithm which is named LDA(Loss Detection Algorithm). The algorithm utilizes the delay from transmitting end to receiving end to distinguish the status of package loss and use the simulation software NS2 to build a platform for analog video. Through it, we can confirm the performance of the TFRC which is improved has bigger progress.
