针对集中式传感器网络在计算样本协方差矩阵的特征值和特征矢量过程中存在的数据拥塞问题,提出一种利用分布式传感器网络计算的解决方案,该方案利用幂法结合一致滤波相关理论,实现样本协方差矩阵的特征值和特征矢量的分布式计算。仿真结果验证了算法的有效性。

Due to the data congestion problem in the process of computing the eigenvalues and eigenvectors of sample covariance matrix by using centralized wireless sensor networks,a scheme which uses distributed wireless sensor networks is proposed.This scheme can compute the eigenvalues and eigenvectors of sample covariance matrix in a fully distributed way by using power method and average consensus filter related theory.Simulation results show the correctiveness and effectiveness of the algorithm.
