摘　　要：针对传感网路中存在的丢包问题,提出了一种新的基于一致性的滤波方法。对于节点的检测数据丢包,该滤波引入一致性协议提高了网络对于丢包的鲁棒性;对于传感器节点之间的通信丢包,该滤波引入了丢包补偿的方法。通过与已有丢包算法仿真对比,该方法具有更好的估计精度。Considering the problem of packet-dropping in wireless sensor network, this paper proposes a new method of filter which is based on consensus. For the failure of data-detection of nodes, the filtering introduces a consensus protocol and improves the network robustness for packet loss; to solve the problem of communication failure between the sensor nodes, the filtering proposes packet dropout compensation method. Through simulation and contrast with the existing packet loss algorithm, this method has better estimation accuracy.
