This paper addresses the problem of tracking space-borne objects of interest (OoIs) with a satellite-assisted collaborative space surveillance network (SSN). It is formulated as a multiple moving-object tracking problem in a hybrid distributed wireless sensor network (WSN) made of both mobile and static nodes. The static nodes may be considered as ground-based sensors with fixed locations, whil...

Version vectors and their variants play a central role in update tracking in optimistic distributed systems. Existing mechanisms for a variable number of participants use a mapping from identities to integers, and rely on some form of global configuration or distributed naming protocol to assign unique identifiers to each participant. These approaches are incompatible with replica creation unde...

The attitude synchronization tracking problem for spacecraft formation flying is investigated in this paper based on sliding-mode control and a Chebyshev neural network (ChNN). A distributed cooperative controller designed group of spacecrafts to guarantee that each individual will track the reference virtual leader presence external disturbances, system uncertainties input saturation. An adapt...
