摘　　要：近红外物联网节点失效波对网络连接可靠率具有重要影响,为提升近红外物联网安全防范力度,构建基于链路生存性流量的节点失效波影响分析模型。构建近红外物联网节点行为信任轮廓,加权求和主观信任值、客观推荐信任值和过往信任值,得到节点行为综合信任值,评估节点是否产生异常;利用节点重要度与负载能力实施失效负载再分配,组建节点失效传播模型,计算随机相邻节点额外业务负载,若高于自身负载能力则节点存在失效风险;根据链路持续时长和剩余容量推导链路生存性,计算相邻节点的引入流量和失效波影响概率,划分节点失效波影响等级,获得近红外物联网不同时段节点失效波影响情况。实验结果表明,所构建模型能准确描述近红外物联网处于不同外部环境下的节点失效波影响程度,为近红外物联网稳定运行提供借鉴。The node failure wave of the near infrared Internet of Things has an important impact on the network connection reliability.In order to improve the security protection of the near infrared Internet of Things,a node failure wave impact analysis model based on link survivability traffic is constructed.Construct the behavior trust profile of the near-infrared Internet of Things nodes,weighted sum the subjective trust value,the objective recommended trust value and the past trust value,get the comprehensive trust value of the node behavior,and evaluate whether the node is abnormal;Use node importance and load capacity to redistribute the failure load,build a node failure propagation model,and calculate the additional service load of random adjacent nodes.If it is higher than its own load capacity,the node has failure risk;Derive the link survivability according to the link duration and residual capacity,calculate the incoming traffic and failure wave impact probability of adjacent nodes,divide the node failure wave impact level,and obtain the node failure wave impact of the near infrared Internet of Things in different periods.The experimental results show that the constructed model can accurately describe the impact of node failure waves in different external environments of the near infrared Internet of Things,and provide reference for the stable operation of the near infrared Internet of Things.
