一种基于定价与信任的网格资源分配算法

该文首先对基于组合双向拍卖的网格资源分配与定价模型进行改进，提出以各类资源的单价定价的算法。然后提出一种等效价格算法，设计基于信任度的价格调整函数，将不同信任度的各节点的报价，都映射为基准信任度下的等效价格。最后基于该等效报价，以组合双向拍卖模型进行网格资源分配。仿真表明所提算法的交易率较高，能防止恶意节点参与交易，所得交易效用可激励买家提高和卖家降低其等效报价。

A Grid Resource Allocation Algorithm Based on Pricing and Trust

This paper firstly improves the combinatorial double auction based grid resource allocation and pricing model, and proposes a unit price based pricing algorithm. Then an equivalent price algorithm is proposed, which designs the trust-based price adjusting function, and maps the bid prices of the nodes which have different trust values into the equivalent prices under the base trust degree. Finally the grid resources are allocated by combinatorial double auction using these equivalent prices. Simulations show the algorithm has high trade rate, can prevent malicious nodes from entering the trade. The trade utility can give buyers and sellers incentives to increase and decrease their equivalent bid prices, respectively.
