网络空间有用信息资源均衡调度仿真

摘要

网格空间有用信息资源的均衡调度,能够有效提高网格空间中有用信息资源的利用率.对信息资源的均衡调度,需要提取滤波输出的资源信息流的关联维特征,设置资源调度的约束函数,完成有用信息资源的均衡调度.传统方法获取节点资源利用率,组建请求流量矩阵,但忽略了设置资源调度的约束函数,导致资源调度效果不理想.提出基于改进膜计算的网格空间中有用信息资源调度方法.利用膜计算方法构建网格空间中有用信息资源流的时间序列分析模型,对拟合的资源信息流进行滤波降噪预处理,提取滤波输出的资源信息流的关联维特征,设置资源调度的约束函数,将蚁群个体引入到膜计算中,给出资源与任务的最优匹配函数,利用上述方案完成对网格空间中有用信息资源调度.仿真证明,所提方法调度精度高,有效提升了有用信息资源的利用率.%A scheduling method for useful information resources in mesh space based on improved membrane computing is proposed.The membrane computing method is used to build time sequence analysis model of useful information resource flow in mesh space,and pretreatment of filtration and noise reduction for fitting resource information flow are carried out,then the correlation dimension feature of resource information flow of filter output is extracted,and constraint function of resource scheduling is set up.Moreover,the individual of ant colony is introduced into membrane computing and the optimal matching function of resources and tasks is given.Thus,the useful information resource scheduling in mesh space is completed.Simulation result shows that the proposed method has high accuracy and can effectively improve the utilization of useful information resource.
