Abstract :
A novel multichannel MAC protocol to solve exposed terminal problem is presented for efficient channel sharing in multihop wireless networks. It employs request-to-send and clear-to-send (RTS/CTS) dialogue on a common channel and flexibly selects conflict-free traffic channel to transmit data packet based on a novel channel selection scheme. The acknowledgment (ACK) packet is transmitted over another common channel, which effectively eliminates the influence of exposed terminal problem. Finally, simulation results show that the proposed protocol outperforms the CAM-MAC protocol on multiple access performance.
