物联网物品信息资源定位优化仿真

Location Optimization and Simulation of Things Information Resources for the Internet of Things

对物联网物品信息资源进行寻址定位,在提高物品使用率方面具有重要意义。由于物联网物品信息资源的多样性及可移动性,使得信息资源寻址定位存在动态性。传统方法采用互联网信息资源寻址模式,针对高复杂性和动态性的物联网集成化背景,无法有效展开和实现信息资源寻址定位,不能保证信息资源寻址定位的准确性。提出一种新的物联网物品信息资源寻址定位优化方法。在分析物联网物品信息资源寻址定位原理模型的基础上,将物联网物品的隐性信息资源名称转换成显性信息资源名称,将显性信息资源名称作为输入信息,构建物联网物品信息资源寻址层次模型。针对构建模型忽略信息资源寻址安全性、无安全机制的弊端,通过添加约束条件与设计安全值对其进行定位处理,利用约束条件保证信息资源寻址的可追踪性与唯一性,通过安全值动态适应信息资源变化,实现信息资源寻址定位优化。实验结果表明,所提方法能够有效实现信息资源寻址定位,整体性能优。

A new location optimization method of goods and information resources in Intemet of things is pro- posed.On the basis of the analysis of the principle model of the information resource addressing and positioning of the Intemet of things,the recessive information resource name of the Internet of things is converted into the name of the dominant information resource,and the name of the dominant information resource is used as the input information to construct the hierarchical model of the information resource addressing of the objects of the Intemet of things.In order to ignore the defects of the security and unsafe mechanism of information resource addressing,the construction model is positioned and processed by adding constraints and designing security values,the traceability and uniqueness of informatioh resource addressing are guaranteed by constraints,the information resources are dynamically adapted to the change of information resources through the security value,and the information resource addressing is realized.Simulation results show that the proposed method can effectively locate inforination resources,and the overall performance is excellent.
