随机空间几何构型下物联网络攻击节点定位

Location of attack nodes in IoT network under random spatial geometry

物联网各节点形成的空间几何构型随机性,决定了攻击节点的空间分辨率出现较大波动,继而影响攻击节点的定位精度。针对物联网下各节点形成的空间几何构型随机性,利用节点脉冲和功率的关联属性不受空间几何构型影响的特征,设计一种攻击节点定位算法。定位算法检测节点脉冲信号,设计最优功率关联算法,关联功率与脉冲的属性。通过关联属性构建节点距离测算定位方法。实验结果表明:文中的物联网攻击节点定位方法,在低、中、高阶三种攻击特征形式下,可以实时准确定位攻击性节点位置,具备较强的实用性。

The randomness of the spatial geometric configuration formed by each node of the Internet of Things(IoT)determines that the spatial resolution of the attacking node fluctuates greatly,which then affects the positioning accuracy of the attacking node.Based on the randomness of the spatial geometric configuration formed by each node in the IoT,an attack node location algorithm is designed based on the feature that the correlation attribute of node pulse and power is not affected by the spatial set configuration.The location algorithm detects the node pulse signal,designs the optimal power correlation algorithm,and correlates the attributes of power and pulse.The node distance measurement and positioning method is constructed by association attributes.The experiment results show that the method of IoT attack node location in this paper can accurately locate the location of the attack node in real time under the three attack feature forms of low,medium and high order,and has strong practicability.
