Automatic recovering node failure in wireless sensor actor network to identify the cutvertex and to meet to the node failure. The network consists of many nodes that are constructed into a tree structure. Once the tree has been constructed the shortest path is found by the Aodv protocol.If a node failure occurs in the shortest path then the cut-vertex could be recovered and the data can be securely passed on to the destination in an alternative route obtained from the routing table. Heartbeat messages acknowledge the node failure. The feasible path is not found by the protocol, and then the network is divided into two or many parts. The MLeDir algorithm is used to identify the network failure and disjoint block of the network. The disjoint block is identified by the MLeDir algorithm and to rectify the disjoint block of failure network nodes. MLeDir algorithm is moving only the respective nodes from source to destination.
