“…On the subject of decentralized and distributed state estimation, interesting approaches can be found in works such as Barooah (2007), Sousa, Oliveira, and Gaspar (2009), and Yuan and Tanner (2010). The closely related area of distributed control has also seen a wealth of relevant solutions, such as those in Chen, Wen, Liu, and Wang (2014), Fax (2002), and Tanner and Christodoulakis (2007), and recent work on the subject of quadratic invariance has offered optimal solutions for certain classes of measurement topologies, see e.g. Lessard and Lall (2011) and Rokowitz (2008).…”
