WebIn this paper we study media access protocols 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-off. WebPackets transmission through wireless media causes errors more than the transmission through wireline networks. This is owing to the noise and fading, high bit error rate (BER), and hidden or...
