摘　　要：为增强无线传感器网络中信标节点之间的信任关系并消除恶意节点,提出基于区块链的信任管理算法。算法核心是对基于行为和数据的信任进行评估。在行为部分从4个维度进行计算,保证全面性;将每个信标节点的行为、反馈以及数据的信任值,广播到基站以生成信任值的区块链;为保证无线传感器网络定位的可靠性和一致性,该算法将信任值最小的信标节点丢弃。实验结果表明,所提算法各方面性能均优于现有算法。To enhance the trust relationship between beacon nodes in wireless sensor networks and eliminate malicious nodes,a trust management algorithm based on blockchain was proposed.The core of the algorithm was to evaluate the trust based on behavior and data.Four dimensions in the behavior part were calculated to ensure comprehensiveness.The behavior,feedback and data trust value of each beacon node were broadcasted to the base station to generate a blockchain of trust value.To ensure the reliability and consistency of wireless sensor network positioning,the beacon node with the smallest trust value was discarded.Experimental results show that the performance of the proposed algorithm is better than that of existing algorithms in all aspects.
