Webof fast covariance intersection. The performance of the proposed method is evaluated with respect to that of fast covariance intersection, which proves its effectiveness even in the case of substantial data reduction. I. INTRODUCTION Wireless sensor networks (WSNs) comprise many au-tonomous but interconnected sensor nodes typically con- Webcommunication. In this work, fast covariance intersection using both quantized estimates and quantized covariance matrices is considered. The proposed method is computationally efcient and signicantly reduces the bandwidth required for data transmission while retaining unbiasedness and conservativeness of fast covariance intersection.
