摘　　要：为了解决目前多信道接入协议面临的多信道隐藏终端和多信道Deafness问题,加入了探测报文和等待报文,采用节点状态表和信道空闲状态表的方法,并采用NS2仿真软件对该协议进行性能仿真。仿真结果表明,该协议解决了多信道隐藏终端和多信道Deafness问题,与DPC协议相比提高了网络吞吐量和信道利用率,降低了网络传输的延迟,增强了网络的性能。In order to solve multi-channel hidden terminal problem and multi-channel Deafness problem that the multichannel 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.
