An Energy Efficient Multichannel MAC Provisioning in MANETS
In this paper, the authors propose a TDMA-based multichannel Medium Access Control (MAC) protocol for QoS provisioning in Mobile Ad hoc NETworks (MANETs) that enables nodes to transmit their packets in distributed channels. The IEEE 802.11 standard supports multichannel operation at the PHYsical (PHY) layer but its MAC protocol is designed only for a single channel. The single channel MAC protocol does not work well in multichannel environment because of the multichannel hidden terminal problem. Their proposed protocol enables nodes to utilize multiple channels by switching channels dynamically, thus increasing network throughput.
