Grid Resource Allocation Based On Trust And The Mixed Combinatorial Double Auction

Grid resource allocation study,the combination of sophisticated economic model has become a very important research direction,and in a variety of economic models,the combination of two-way auction model because it is very suitable for large-scale grid environment,heterogeneous,dynamic,etc.features,now has become the focus of grid resource allocation study;In addition,the trust mechanism provides a suitable grid of open,distributed and dynamic properties of security decision-making framework,Trust model able to trust the entity described in the grid and to build trust relationships between grid entities,making the grid system becomes more robust,secure;trust model for grid discipline mechanism to punish malicious nodes to lose some privileges until the expulsion of the grid mesh,making the grid system becomes more reliable.The main work of this paper as following:Fist,A Mixed combination of double auction mechanism for a single node to play the role of the traditional auction mechanism,a Mixed combination of the issues raised double auction mechanism that raised at a time,supply and demand nodes simultaneously raise aspirations,namely acting as both buyers and sellers,or the buyer and seller in any party supply demands and needs of the demands of this buyer seller node node will be realized at auction,making the auction trading closer to the opt imum deal.Second,A mixed combination of double auction mechanism for a single node play a role in the problem of the traditional auction mechanism proposed mixed combinations of double auction mechanism that raised at a time,supply and demand nodes simultaneously raise aspirations,namely to buy a house at the same time play and the seller,or the buyer and seller in any party supply demands and needs of the demands of such a buyer seller node will be realized at auction,making the auction trading closer to the optimum deal.Second,Grid Resource Allocation proposed Mixed combinations of trust and based on double auction,the trust mechanism in conjunction with the hybrid combination of two-way auction together is a core part of this paper,the trust mechanism is introduced through trust price adjustment function,the price adjustment function allows for Buyer confidence threshold on the left to quickly lower the price,the right of the trust to quickly raise the threshold price;trust for the seller on t he left to quickly raise the threshold price,in the right confidence to quickly lower the threshold Price.Trust mechanism characterized by safety,quality of service and other aspects of the combination of a Mixed combination double auction in the auctio n to maximize efficiency and ensure rational resource unit of utility with positive incentives,etc.,so that the grid resource al ocation model is superior to the existing scheme.Third,A combination of an improved two-way auction grid resource allocation method under the policy,based on a combination of two-way grid resource allocation auctions are generally divided into two steps: The first step,the subject of race wins and determined;The second step,Winner of resource allocation and pricing.Select the subject of race wins and identify the problem proved to be an NP-hard problem,a lot of literature at the present stage of its in-depth analysis,including the improved algorithm,optimization and improvement of the two aspects of the mechanism.This article will be the subject of race wins and determined integration into the subject of race wins among resource allocation and pricing.And trading on behalf of different parties translate into different resources agency,proposed new combination double auction of grid resource al ocation policy.
