【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。
[Abstract]:A Energy-saving data Transmission method C _ 2 MIMO. based on clustering and Cooperative MIMO for event driven disaster Monitoring Sensor Network First, monitor and relay clusters are constructed in the network, and a main cluster head and several slave cluster heads are selected from the cluster, which act as cooperative sending and receiving nodes of cooperative MIMO. Then, the data is transferred from the monitoring cluster to the Sink node by the cooperative transfer method. From the energy consumption model of cooperative MIMO and the results of simulation experiments, it can be seen that C2 MIMO can adapt to long distance relay transmission and has strong endurance to channel deterioration.
