中文摘要:针对现有WSN信任模型没有考虑节点交互距离影响推荐信任和节点物理距离影响能量消耗的问题,提出了基于节点交互距离的推荐信任度和基于物理距离的能量信任度计算方法,及与行为信任度、能量信任度进行信任融合的方法。引入簇头结点更新算法保证了每个时间片最高信任度节点是簇头节点。实验表明:基于节点交互距离与物理距离的WSN信任模型及算法提高了节点间的交互成功率和交互稳定性,降低了交互时延波动率,模型稳定性有明显提高。
中文关键词:信任模型  交互距离  交互成功率  交互时延  WSN
 
Research on WSN Trust Model Based on Interaction Distance of Nodes and Physical Distance
Abstract:The definition and calculation method of comprehensive trust,energy trust based on node physics distance and recommend trust based on the node interactive distance were presented. Trust fusion method of energy trust based on node physics distance,recommend trust based on node interactive distance,competence trust and behavior trust was presented. On this basis,a wireless sensor network trust model based on node physics distance and interactive distance was built,the Alternative Algorithm for Cluster Head Node Updating was put forward. The experiments show that WSN trust model based on node interactive distance and physical distance and related algorithm improve the node interaction success rate and the stable. At the same time,the fluctuation rate of interactive delay is reduced. The stability of the model is improved obviously.
