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.
