Abstract: In order to improve the throughput performance
of Medium Access Control (MAC) schemes in wireless communication networks, some researchers proposed to divide a single shared channel into several sub-channels: one as control subchannel
and the others as data sub-channels. In this paper, we analyze and evaluate the maximum achievable throughput of a class of generic multi-channel MAC schemes that are based on the RTS/CTS (Ready-To-Send/Clear-To-Send) dialogue and on ALOHA contention resolution. We study these multichannel MAC schemes under two split-channel scenarios: the fixed-total-bandwidth scenario and the fixed-channel-bandwidth
scenario. In the fixed-total-bandwidth scenario, we show that
the throughput of the multi-channel MAC schemes is inferior
to that of the corresponding single-channel MAC scheme, which
sends the RTS/CTS packets and DATA packets on a single shared
channel. For the fixed-channel-bandwidth scenario, where CDMA
or similar techniques can be applied, we derive the optimal
number of the data sub-channels that maximizes the throughput.
The analytical framework that we derive in this paper can also
be used to evaluate other contention resolution technique, when
the average contention period is known.
