Fl. Lo et al., MARKOV ANALYSIS OF MULTICHANNEL STAR-CONNECTED NETWORK WITH CHANNEL SENSING AND COLLISION DETECTION, IEE proceedings. Communications, 144(5), 1997, pp. 331-335
When many stations need to communicate with a central server, the simp
lest way to allow them to transmit messages to the server is to use a
non-centralised contention access protocol. One of the most efficient
of these protocols is channel sense multiple access with collision det
ection (CSMA/CD). Exact analyses of single-channel CSMA/CD networks ha
ve been done, but, so far, all the analyses of multichannel CSMA/CD ne
tworks in the literature have used approximations to simplify the proc
ess of finding the transition matrix. The paper presents an exact Mark
ov analysis of a multichannel CSMA/CD network. It is shown that such a
multichannel system performs better than an equivalent network having
just one channel.
