Abstract :
This work investigates the TCP-friendliness of a particular congestion control mechanism, the TCP friendly rate control protocol (TFRC), when it is employed to regulate the transmission rate of nonTCP sources competing for bandwidth with different TCP flows (Reno, Sack and Westwood) in an IEEE 802.11b wireless LAN. Throughput of simultaneously active TFRC and TCP flows have been both experimentally measured and investigated through simulation, revealing that the wireless indoor radio channel plays a significant role on such parameter. Moreover, some useful insights have been derived on the behavior of TFRC and its degree of friendliness in an environment featuring a low degree of statistical multiplexing, such as the wireless context examined.
