融入权重的云服务预订协商折中算法

摘要

云服务预订协商机制中使用的折中算法直接影响协商的速度，但已有的折中算法并没有考虑历史协商结果对于当前提议的影响，限制了协商的速度。对此，提出融入权重的云服务预订协商折中算法。算法充分考虑历史议题相关性和时间效应对协商提议的影响，协商提议权重的变化采取从历史资源中发掘知识的方法进行动态调整并给出动态权重更新方案。通过构建基于代理的云计算仿真平台，对提出的观点进行验证，证实了此算法具有较快的协商速度。%The tradeoff algorithm in negotiation mechanism for cloud service reservations direct affected the speedand success rate .But the existing tradeoff algorithm does not consider the historical results of the consultation for the impact of the current proposal ,it limited the speed of the negotiation .In this regard ,the tradeoff algorithm integrated into the wights in negotiation for cloud service reservations is proposed .The algorithm fully consider the historical issues related and time effects of negotiation proposal ,according to data mining from history resources .Simulation experimental results showed that the algorithm reach faster agreements .
