| 摘 要： | 在Ad Hoc无线网络多信道介质访问控制协议DCA中，所有移动节点在一个预留的公共控制信道上传送控制信息，即使控制信道空闲也不能在其上进行数据传输。针对DCA这种信道利用率不高的问题，提出一种改进方法，利用空闲控制信道进行数据传输。实验结果表明，改进后的DCA可以增加网络吞吐量和信道利用率。

| Abstract: | In the multi-channel MAC protocol DCA,which is designed for Ad Hoc networks,all the mobile nodes transmit the control information on a reserved control channel,and the control channel can not be used to transmit the data even though it is free.As to the low utilization of DCA,an improved method is proposed,which uses the control channel as a data channel when the control channel is free.The results show that the improvement on DCA can increase the throughput of the network and the utilization of the channel... |
