Abstract :
A study of the effect of the optical path delay on the effectiveness of the request to send/clear to send (RTS/CTS) exchange in high-speed IEEE 802.11 wireless LAN (WLAN) over fiber networks has been carried out. It is shown that although the fiber delay might violate some of the timing boundaries of the medium access control (MAC) protocol, with a careful choice of the RTS threshold parameter, which determines when the RTS/CTS is used, these networks can benefit significantly from the four-way handshake even without the need for modifying the existing protocol.
