Abstract :
In this paper, we propose an asynchronous multi-channel MAC (AM-MAC) protocol for cooperative network, which keeps nodes aware of all the state information and introduce cooperative transmission into asynchronous multi-channel environment. This Multi-channel MAC design adds a helper-confirm phase in channel negotiation process and also different information tables and learning methods. As we analyzed the properly designed MAC frames and handshake schemes make it perfect in data channel selection and helper confirmation. Simulations have shown that the network throughput of AM-MAC is much higher than none-cooperative multi-channel MAC protocol when causing less dropped packets.
