Ordinary wireless sensor network nodes are hardware fixed and unable to change their node configuration during service.This paper proposes a new self-repairing method based on bio-inspired evolvable hardware for wireless sensor network node.By using bio-inspired evolvable hardware,the nodes can be implemented with self-repairing ability which can dynamically change the node's hardware structure and behavior to repair themselves in case of component hardware failures.This paper proposes a bio-inspired self-repairing method for wireless sensor network nodes.A FPAAs-based self-repairing node is developed and its self-repairing function is evaluated.Experiments show that the node can diagnose the failures and recover to normal working state automatically.The research presented can improve the safety and robustness of the wireless sensor network.
