Abstract
TCP is the current dominant transport protocol, mainly used in fixed networks. It is well known that TCP performance may degrade over paths that include wireless links, where packet losses are often not related to congestion, but to the unreliability of the transmission medium. In this paper, we examine this problem considering a wireless link based on Bluetooth radio equipment. Bluetooth (BT) is a low-cost system in the unlicensed 2.4GHz band. It provides a reliable data transmission using fast frequency hopping technique and Stop-and- Wait ARQ scheme. In our experiments, we have studied the performance of a heavy file transfer over a BT link, with different environmental conditions and BT radio packet formats. Results show that the best FTP performance in a wide range of radio channel conditions is obtained by using long non-FEC-protected radio packets. Nevertheless, in particularly hostile situations, the intermediate-length packet format appears more suitable. Furthermore, analysis has focused the possibility of inefficiency due to bad interaction between TCP and BT retransmission mechanisms.
