In WSN (Wireless Sensor Network) will get partition into multiple number connected elements due to the failure of a number of its nodes, that is termed has cut. The authors tend to contemplate the drop back of detective work cut by the remaining nodes of a wireless sensor network. They tend to propose associate degree algorithmic rule that enables. Each node to notice once the property to a specially selected node has been lost. One or a lot of nodes that are connected to the special node when the cut. The rule of algorithmic is distributed and not synchronized: each node has to communicate with solely those nodes that are among its communication limit.
