摘要： 在云计算环境下，基于连续双向拍卖(CDA)机制的资源分配模型，给出资源供需双方各自的报价策略以及节点资源的失效规律，提出一种基于CDA机制和节点可信性的动态资源分配策略。Matlab仿真结果表明，该策略能保证动态分配资源的可信性，有效提高动态节点资源的执行效率以及最大限度地满足用户的服务质量需求。

Abstract: This paper introduces the resource allocation model which is based on the Continuous Double Auction(CDA) mechanism and the pricing strategy of the supplier and the demander under cloud computing environment. After the law of the failure of resources nodes is analyzed, it promotes a dynamic resource allocation strategy which is based on the CDA mechanism and the credibility of the nodes. Matlab simulation results show that the strategy can ensure the creditability of the resources, improve the operation efficiency and maximize the Quality of Service(QoS) when dynamically providing resources.

Key words: cloud computing, Continuous Double Auction(CDA), credibility, resource allocation, Quality of Service(QoS)
