多仪表数据移动云计算处理切换策略研究

摘要

In order to improve the service performance of the mobile cloud computing for multi -meter data , the handoff strategy of mobile cloud computing was studied in this paper , and a new handoff method was proposed based on threshold decision and network selection .This method can be divided into two steps .Firstly, a threshold decision is adopted to decide whether or not to need to be switched .Secondly , the multiple attribute decision-making method is adopted to select the best alternative network .Experimental results show that the proposed handoff method has better performance than the vertical handoff method and network selection switching method , and the three indexes of the switching frequency , time, and mobile terminal energy consumption are outstanding .%为提升多仪表数据移动云计算的服务性能，文中就移动云计算的切换策略展开了研究，提出了一种基于阈值判决和网络选择融合的移动云计算切换方法。这种方法将移动云计算的切换过程分为两个步骤，首先通过阈值判决来决定是否需要进行切换，其次采用多属性决策的方法为切换选择最佳的备选网络。实验结果表明，文中提出的切换方法比垂直切换方法和网络选择切换方法具有更加优秀的切换性能，在切换次数、完成时间、仪表检录终端能耗三个指标上均表现出突出的优势。
