N2 - Wireless sensor-actor networks (WSANs) are a core component of Internet of Things (IOT), and are useful for environments that are difficult and/or dangerous for sensors to be deployed deterministically. After random deployment, the sensors are required to disperse autonomously without central control to maximize the coverage and re-establish the connectivity of the network. In this paper, we propose a Physarum inspired self-healing autonomous network connectivity restoration algorithm that minimize movement overhead and keep load balance. The mechanism to select the alternative nodes only involves the one-hop information table, and depends on actor node location from base station (regions of k-influence), and residual energy. Our model achieved almost complete coverage, and fault repair in one or two rounds with minimal number of movement overhead.
