Abstract: In order to solve multi-channel hidden terminal problem and multi-channel Deafness problem that the multi-channel access protocols are facing,this paper added in probe packet and wait packets and adopted the node status table and the channel idle state table.And we also used NS2 simulation software to simulate its function for this protocol.The simulation results show that the improved protocol resolves the multi-channel hidden terminal problem and multi-channel Deafness problem and raises the network throughput and channel utilization,reduces the network transmission delays,enhances the performance of the network compared with DPC protocol.

Key words: Multi-channel,Access protocol,Throughput,Delay
