Real Time Applications (RTAs) have stringent requirements. Congestion in the network results in packet loss, delay and reduction in throughput which are not tolerable by RTAs. Proper congestion control mechanisms are necessary for RTAs. TCP provides congestion control mechanisms. But it is a protocol which is designed for wired networks. TCP treats packet loss as an indication of congestion which is not true in wireless networks. In wireless networks packets may be lost due to various other reasons. UDP has no congestion control mechanisms and is not good for the stability of the Internet. TCP Friendly Rate Control (TFRC) protocol is designed by Internet Engineering Task Force (IETF) especially for RTAs. This paper studies the performance of TFRC, TCP and UDP in wireless environment.
