Abstract: A wireless sensor network (WSN) is a deployment of a large number of small, inexpensive, self powered devices that can sense, compute, and communicate with other devices for the purpose of gathering local information about a physical environment. An distributed algorithm to detect “CUT“ in Wireless sensor networks has been proposed here, which identifies the failure of a node or a set of nodes that separates the network in to two or more components. Algorithm is iterative and asynchronous.

Keywords: CCOS, CUT detection, DOS, network separation, Wireless sensor network.
