移动网络中教学资源均衡分配优化仿真研究

摘要

对移动网络中教学资源均衡分配的优化,可以有效的提高教育资源的利用率.由于资源均衡分配主要与节点性能指数与资源消耗指数相关,使得教育资源负载能力不稳定.传统方法主要通过预测当前网络资源负载能力为主,未对适配因子进行计算,导致分配效果差.提出基于多代理节点下的教学资源均衡分配方法.上述方法先利用节点加入方法定义出移动资源中心物理机集合的负载不均衡度,计算出虚拟机与物理机的匹配度,给出虚拟机的学习资源需求的约束范围,并计算当前资源消耗指数,得到资源节点综合性能指数,计算出节点性能指数与资源消耗指数的适配因子,以计算的结果为依据完成对移动英语学习资源均衡分配.仿真结果表明,所提方法均衡性好,为国内英语移动学习资源均衡分配研究提供了科学的依据.%An equilibrium assignment method of teaching resource in the mobile network is proposed based on the multi-agent node.Firstly,the load imbalance degree of physics machine set in the mobile resource center is defined by using the node adding method,and the matching degree between the virtual machine and physics machine is worked out.Then,the restrain range of learning resource demand in the virtual machine is given out,and the current resource consumption index is calculated.Moreover,the combination property index of resource node is obtained and the adaptive factor of node performance index and resource consumption index is worked out.Finally,the equilibrium assignment of mobile English learning resource is completed according to the calculation results.The simulation results show that the method has good equilibrium.It can provide scientific basis for the research on the equilibrium assignment of civil mobile English learning resource.
