| 摘 要： | 文章针对无线传感器网络,采用时分复用的方式,对现有的BMA协议提出了一种改进方法--DABMA.通过优化原协议的时隙分配方式,提高了信道的利用率,减少了空闲监听的时间,避免了冲突和串音,特别是针对需要传输的数据节点较少、数据量较大的情况下,节省了能量,延长了网络生存期.

| Abstract: | For the wireless sensor networks,the paper presents a method called DABMA,which is an improvement over the existing BMA protocol,using the time division multiple access manner.By optimizing the original protocol with the slot allocation,the DABMA increases utilization of the channel,reduces the idie time of listening and avoids conflicts and overheads.Particularly in the case of transmission with a large amount of data but a small number of nodes,the method reduces energy consumption and prolongs the survival of the network. |
