摘　　要：文章针对节点具有双收发器多信道的自组网,对动态分配协议进行了改进,使得一些短报文可以在没有可用数据信道时直接在控制信道上传输,从而解决信道利用率不高的问题。研究表明,改进后协议的网络吞吐量有了显著的提高。This paper presents an advanced DCA MAC protocol for multi-hop ad hoc network.When the number of data channel is few,the control channel will keep idle for a long time when all data channels are busy,which lead to poor throughput performance of network.The advanced DCA MAC protocol presented in this paper allows short data packets to be transmitted in control channel when there is no available data channel.Results show that the advanced DCA MAC protocol can improve the throughput in a multi-hop ad hoc network.
