| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | In this paper, distributed estimation method with optimal aggregation based on belief propagation is proposed. In the sensor networks, each node aggregates received messages and own measurement. In the calculation of the aggregation, each node minimizes variances of aggregated values based on variances of received messages. The calculation of the variance of the aggregated values in each node, belief propagation is utilized. Distributed estimators of all node provide maximum likelihood estimation which are equal to the ones calculated from all of individual measurements. Finally, we extend the proposed method to model based synchronization for delayed sensor networks. | |
