- Due to wide area of innovation in wireless technology, Wireless Sensor-Actor Networks (WSANs) have been the interesting area of application for last two or three decades in various fields. In WSANs, sensor node will explore the environment and transmit the gathered information to actor nodes. Actor node gathers or aggregates that information and performs specific operations in response to various events. Actors have to work together so it is essential to retain a strongly connected network topology at all the time. Since, actors perform in hostile environment, so they are prone to failures. Moreover a failure of an actor node leads to partition of the network into disjoint blocks and would thus violate the connectivity goal. For the recovery of faulty nodes, there is a requirement of location table for initiating the recovery process. LeDiR is a localized and distributed algorithm for single node failure that depends on local view of the node about the network. But in some real time situations, like bombardment and other natural calamity, where large number of node get disrupted or ruptured. There is a requirement to reconsider the above said schemes for multiple node failure recovery. In this paper, a new phase of LeDiR is introduced that may recover simultaneous node failure. Simulation result shows that LeDiR for multiple node failure (MLeDiR) outperforms conventional LeDiR methods in terms of total number of nodes moved and average distance moved during the recovery process
