Gürkan Gür, Suzan Bayhan, Fatih Alagöz · IGI Global eBooks · 2009
This chapter introduces the QoS issues and support in transport protocols for wireless multimedia transmission. After an overview of the transport layer functionalities in a transmission and the multimedia characteristics, conventional transport layer protocols: transmission control protocol (TCP), and user datagram protocol (UDP) are described. In this chapter, some of the proposed modifications to these protocols in order to improve multimedia transmission quality in wireless networks are also summarized. Particulary, UDP Lite, TCP friendly rate control protocol (TFRC), and real-time transport protocol (RTP)--real-time transport control protocol (RTCP) are mentioned. Finally, the chapter is concluded with some discussions on the current trends in transport protocols for wireless multimedia transmission and on some of the ongoing research issues.
