普适计算中间件的自适应机制研究
Research on adaptive strategy for pervasive computing middleware
-
摘要: 针对目前自适应中间件平台未考虑服务质量的问题,提出了一种适合普适计算中间件的自适应机制.在自适应机制中加入QoS属性特征,引入服务合约的概念,并将遗传算法应用于优化问题,较好地实现了自适应效果.Abstract: To solve the ignorance of service quality of adaptive middleware platform,an kind of adaptive strategy suitable for pervasive computing middleware was put forword.In the strategy QoS feature is added,service contract concept is introduced and genetic algorithm is used to solve optimizoction problem.Thus better adaptive effect has been achieved.
