Abstract
In recent years, a wide variety of mobile computing devices
has emerged, including portables, palmtops, and personal
digit al assistants. Providing adequate network connectivity y
for these devices will require a new generation of wireless
LAN technology. In this paper we study media access pro-
tocols for a single channel wireless LAN being developed at
Xerox Corporation's Palo Alto Research Center. We start
with the MACA media access protocol first proposed by
Karn [9] and later refined by Biba [3] which uses an RTS-
CTS-DATA packet exchange and binary exponential back-
