摘要/Abstract

摘要：

提出基于可信拍卖机制的视频移植定价策略LBAS，降低视频服务的单位成本。首先，依据市场经济价格规律，由视频提供商以未来视频请求为自变量制定视频类的服务价格，有利于降低视频提供商费用支出；其次，设计了距离函数，衡量视频服务单位成本，计算云提供商给出的价格和视频提供商预期价格之间的差距，确定能赢得竞拍的云提供商；再次，以云提供商预期收益为基准，提出可替换视频集的视频分配算法，提升云提供商的满意度和降低视频提供商的费用；最后，改进联盟抑制算法 AEM，使其适应低价格拍卖机制并加入了视频数量检测机制，能避免由于竞拍者联合而使视频提供商利益受损。与当前最新的移植方案VMC 相比，实验结果表明LBAS能进一步降低约10%的费用。

Abstract:

In order to decrease the unit costs of video service, pricing strategy LBAS for video migration based on truthful auction mechanism was proposed. Firstly, according to the principles of market economy prices, service prices using the future video demand as independent variable were laid down by the VoD provider, so as to decrease the costs of the VoD provider. Secondly, a distance function was designed to measure the unit costs of video service. The proposed function computes the distance between the costs providing by cloud providers and expected prices offering by the VoD provider, and the obtained distance was used to determine who can win the auction. Thirdly, replaceable video alloca-tion algorithm based on the benefits of cloud providers was presented. The proposed algorithm increases the satisfaction of cloud providers and decreases the costs of the VoD provider. Finally, the AEM algorithm was improved through estab-lishing the detection mechanism of video number, so as to adapt to the low-bid auction. The improved algorithm avoids the collusion among bidders and assurances the benefits of the VoD provider. The experiment results demonstrate that LBAS can decrease 10% of the costs compared to the VMC strategy.
