TAMMAC: An Adaptive Multi-Channel MAC Protocol for MANETs

The use of multiple channels in wireless networks could provide performance advantages in reducing collisions and enabling more concurrent transmissions. So et al. proposed a multi-channel MAC protocol, which uses a single transceiver and divides the beacon interval into two parts: channel negotiation and data transmission. However, the fixed length of channel negotiation interval limits the channel utilization. We propose a new single transceiver MAC protocol, named traffic aware multichannel medium access control (TAMMAC), that can exploit multiple channels with smart window increase and decrease rules to adjust the contention window size dynamically and properly. The simulation results show that the proposed protocol achieves higher aggregate network throughput than other schemes under various traffic loads.
