摘　　要：为事件驱动的灾害监测传感网提出一种基于分簇和协作MIMO的节能数据传输方法C2 MIMO。首先,在网络中构造监测簇和中继簇,从簇中选出一个主簇头和若干个从簇头,它们充当协作MIMO的协作发送节点和接收节点。随后,利用协作传递的方法将数据从监测簇逐簇传递,直到交付给Sink节点。从协作MIMO的能耗模型和仿真实验的结果可知,C2 MIMO能够较好地适应长距离的中继传输,并对信道恶化具有较强的忍耐能力。An energy-efficient data transmission schemed, named C2MIMO, was proposed for disaster monitoring sensor networks. Because the scheme is based on clustering and cooperative Multiple-Input Multiple-Output （MIMO）, the monitor and cluster are constructed first. During this process, one primary header and some slave headers are selected as cooperative sending and receiving nodes. Then, the network delivers the gathered data to sink cluster-by-cluster. Through the cooperative MIMO energy consumption model and simulation results, the C2MIMO scheme shows its adaption to long distance transmission and bad channel status.
