Distributed Hash Table (DHT)-based protocols are new approaches proposed to Wireless Sensor Networks (WSN). Their main advantage resides on the easy integration of DHT-based WSN into the Internet Of Things. However, these protocols face multiple challenges in their bootstrapping phase, especially at the case of randomly deployed WSN. We presented in a recent work a bootstrapping protocol for use in DHT-based protocols having the structure of ring in static WSN. However, in most cases, there are some nodes that may fail or move in the network. Bootstrapping should take into account such situations in order to achieve better performance. In this paper, we propose a distributed local recovery method for use in our bootstrapping protocol that allows it to handle efficiently nodes failure and mobility. Simulation results have shown that our proposed approach is able to ensure the local recovery in a timely and energy-efficient manner.
