“…At present, there is an increasing number of researchers that recognize the importance of the DF problem over SNs (Bu et al, 2019(Bu et al, , 2018He et al, 2020;Liu et al, 2019;Wang et al, 2020;Yang et al, 2019). Some typical research directions include that the distributed H ∞ filtering (Dong et al, 2013;Han, Wang, Chen et al, 2021;Qu et al, 2019;Shen et al, 2010Shen et al, , 2011, and the distributed Kalman filtering (Ji et al, 2017;Li, Dong et al, 2019;Wang et al, 2019;Wu et al, 2018;Yang et al, 2020), and distributed set-membership filtering (Liu et al, 2019;Ma et al, 2017). As for DF problems, each node has its own filter through the available information from both itself and its neighbouring sensor nodes.…”
