This paper presents an insect-inspired synchronization method for ISA 100.11a industrial wireless network. The proposed method is adapted from the synchronization method of insects, especially the male fireflies from South-East Asian countries. The self-stabilize firefly synchronization method enables all the nodes in the network to recover from the master failure. For this, all slave nodes can cooperate in a complete self-organized manner to achieve time synchronization. The simulation result shows that the proposed method achieves complete fault-tolerance during the recovery from the master failure and has robust synchronization against the interference. It is possible to achieve synchronization accuracy without any central control.
