Comparisons Of Network Transports Protocols Over Wireless Network

Nowadays, there are severaJ transport protocols that can be used for audio and video transmission over wireless network. There are TCP; Transport Control Protocol, UDP; User Datagram Protocol, DCCP; Datagram Congestion Control Protocol, SCTP; Stream Control Transmission Protocol and, TFRC; TCP Friendly Rate Control. TCP is a connection oriented transport protocol that provides a reliable byte stream to the application layer. TCP uses an ARQ mechanism based on positive acknowledgments. It supports a congestion avoidance mechanism to reduce the transmission rate when the network is overloaded. UDP is a simple transport protocol. UDP does not guarantee any reliability and in order delivery of the packets. It allows multicast and broadcast transmissions. It is suitable for applications that need to define the sending rate, prefer packet losses to jitter or have strong delay requirements. The project that I have planned for Project Satjana Muda is entitled Comparisons Of Media Streaming Protocols over Wireless Network. The objective ofthis project is to investigate the performance of the four most common and popular transport protocol, UDP, TCP, SCTP and RTP over wireless network. A simulation network using NS-2 is developed in this project for measuring the packet loss, packet delay, and throughput.
