Abstract: We analyze the delay performance of RTS/CTSbased
(Request-To-Send/Clear-To-Send) multi-channel MAC
(Medium Access Control) schemes for wireless networks. These
schemes usually employ multiple data subchannels for data
transmission and one control subchannel to send the RTS/CTS
dialogue for channel reservation. Through theoretical analysis
and simulations, we show that, in fully-connected networks, such
multi-channel MAC schemes suffer longer delays than the corresponding
single channel MAC scheme, that puts the RTS/CTS
dialogue on the same channel as data packet transmissions. This
conclusion holds even when data packets have different priorities
and higher priority traffic is sent ahead of lower priority traffic.
