dc.description.abstract | This paper presents AMCM, a traffic-adaptive multichannel MAC protocol that increases the capacity of wireless network by enabling multiple concurrent transmissions on orthogonal frequency channels using a single halfduplex transceiver. AMCM is based on aie IEEE 802.11 MAC but provides fine-grain, asynchronous coordination among locally interfering nodes for channel negotiation. By incorporating bad-awareness, channel availability awareness and batch transmissions, our window-based approach achieves high channel utilization under varying load while avoiding the control-window saturation problem as the number of channels increases. For single-hop scenarios, we show that at low load AMCM is comparable to IEEE 802.11 MAC, while under high load AMCM delivers almost N x improvement gain over IEEE 802.11 MAC protocol where N is the number of channels. AMCM also outperforms existing multi-channel MAC protocols [8, 11] by 100% and 150% respectively under high load at a lower hardware cost and complexity. In multi-hop scenarios, AMCM achieves performance improvement of 190% and 90% for both dense and sparse network over IEEE 802.11 MAC respectively. In both scenarios, AMCM achieves close to full utilization of all channels with good protocol efficiency. © 2006 IEEE. | |
