This paper studies distributed filtering problem of homogeneous sensor networks. Just part of sensors can get observations of the process and consensus based filters are applied. Both the distributed detectability and the suboptimal filter design are investigated. By converting the stability problem of estimation errors of sensors under time-varying topologies to the robust stability problem of some...
This paper studies distributed estimation of linear dynamical target in homogeneous sensor networks. Just some sensors can get observations of the target. A distributed estimator composing of Luenberger observers and consensus strategy is applied. Based on spectral radius analysis and algebraic graph theory, necessary conditions of distributed detectability are given for time-invariant and randomly...
