“…These phenomena are customarily referred to as the incomplete information that has attracted much research interest in developing filtering schemes [1], [8]- [10], [16]- [18], [22], [23], [25], [32], [37], [39], [41], [43], [46]. However, when it comes to the event-based distributed filtering problems with incomplete information, the corresponding results have been very few owing mainly to the lack of appropriate techniques for coping with 1) the complicated node coupling according to the topological information and 2) the demanding triggering mechanism accounting for the limited capability.…”
