Abstract – The effectiveness of wireless sensor-actor networks deployed in search and rescue, battlefield reconnaissance, surveillance, and other applications depends on inter-node interaction. In WSAN, sensors probe their information from the physical world and forward their data to actor nodes then actors collaboratively respond to achieve predefined application mission. The network can be partitioned into disjoint blocks if an actor suddenly fails and violate such a connectivity goal. The simultaneous recovery scheme imposes a high node relocation overhead and bunch of topology changes and also extent inter-actor data paths. Our approach explore the simultaneous node recovery from a multi-node failure with maintain the nominal topology change by using the Least Disruptive PILOT (Pre-defined Intelligent Lightweight topology management) Node (LDPN) algorithm. LDPN algorithm, use a set of PILOT nodes that can be used whenever a link failure between two sensor nodes. This approach removes the faulty node by using the best PILOT node and it act as a bridge between two neighbors of failed node. The LDPN algorithm can reestablish the network connectivity and make sure that the minimal topology changes within the network.
