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.
