针对现有无线传感器网络节点硬件固定,不能重新配置的问题,设计了一种全新的基于仿生硬件的无线传感器网络节点自修复方法,采用仿生硬件实现动态可重构无线传感器网络节点,以使节点能够自主地、动态地改变自身的结构和行为,在其部分硬件失效情况下进行节点的仿生自修复.该研究提出了相关节点的仿生自修复方法,研制了基于现场可编程阵列的仿生自修复节点,并通过实验验证了节点的自修复能力.对于提高无线传感器网络的鲁棒性和安全性具有重要意义.%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.
