物联网架构下数据库信息远程共享方法仿真

摘要

A new remote sharing method of database information under the architecture of Internet of things is proposed.The principle of remote sharing of database information is analyzed.The remote sharing structure of database information is constructed under the Internet of things architecture.The number of semantic mapping,data type mapping and constraint mapping are at least regarded as the optimization goal,and a multi-objective optimization function of database information sharing design is put forward.Interest degree constraints are introduced to provide personalized service for users.The particle swarm optimization method is optimized through quantum mechanism.The objective function of remote sharing of database information under the Internet of things architecture is optimized by using the optimized particle swarm optimization,and the optimal sharing scheme is obtained.The simulation results show that the proposed method can improve the user experience and ensure the real-time information sharing.%传统数据库信息远程共享方法可在一定程度上实现数据远程共享,但提供共享信息实时性差,且忽略个性化服务.为此,提出一种新的物联网架构下数据库信息远程共享方法.分析了数据库信息远程共享原理.构建物联网架构下数据库信息远程共享结构,将语义映射、数据类型映射与约束映射次数最少看作优化目标,提出数据库信息共享设计的多目标优化函数.引入兴趣度约束,为用户提供个性化服务.通过量子机制对粒子群方法进行优化,利用优化粒子群方法对物联网架构下数据库信息远程共享目标函数进行求解,获取最优共享方案.仿真实验结果表明,所提方法可提高用户体验,保证信息共享实时性.
