Grid Payment System Based On Computational Economic Model

Grid is an important development trend for parallel and distributed computing technology nowadays,aiming at realizing sharing the large quantity of heterogeneous resources largely distributed geographically by Internet.As the commodities in the market environment,resources on the grid are also a kind of commodity,the behavior of resources consumption is a reasonable trade-off action.The providers supply resources,the consumers use them.The nature of the market is selfish,which is designed to benefit the participants in the market.But the selfish behavior of the market will lead to the results disobey the laws of the market,such as price monopoly, inflation and price imbalance and so on,and bring on instability and collapse of the market.Referring to the model used to regulate the market of human society,a computing economic model should be set up in the grid market.The mechanism of the model can regulate the relationships between supply and demand and the prices of the resources in the grid,and provide a fair solution.According to the principle of the resources are not used for free,it will involves the payment problem between the consumers and the providers.At present,the research on the billing and payment problems of the computing economic model in the grid is still relatively small,especially the payment issues.So,how to combine the computing economic model with efficient payment services is one of the key issues that should be resolved.The author has summarized several computing economic models of the gird market,and analyzed the characteristics and shortcomings about the present grid systems,then designed a framework of grid computing economic model based on the relationships between supply and demand.Meanwhile,it has also deeply researched the strategies and algorithms of the computing economic model.With regard to the resource payment strategy of the provider and the consumer,the paper has introduced three payment methods,and analyzed the close relations between the payment methods and the credit problem.So,it proposed the credit algorithms of the resource, the provider and the consumer.Most of the time,the resource provider is also the resource consumer in grid market.To solve this problem,it has given a kind of method to uniquely identify the user by calculating the IP address.As for the research on the price strategy,it has given the pricing model of the resources which can realize the price control of the resources to maintain the stability of the market.The pricing model is influenced by the relationships between supply and demand and the credit of the resources.In order to guarantee the profit of the consumer,this paper has also proposed the bidding model of the consumer.Through simulating experiment,the model has compared with the commodity market model under the same conditions, the result shows that the dealing amount per unit time is higher and the changing trend of the average price of the resources over time is more stable.Using the technologies of JSP,Servlet,Struts,Hibernate and MySQL database system,a kind of gird payment system based on the improved computing economic model has been designed and implemented.This system is mainly provides the digit manufacturing resources of grid.It realizes the trading of the resources under the controlling of the economic model in the grid market.The consumer could pay the provider according to the payment method they have agreed through good interface in the system which creates a fair trading environment for the grid trading users,in order to promote the efficient use of the limited grid resources and provide opportunities for the users to obtain mutual profits.
