Research on cooperative cognitive radio network resource double auction

Abstract

The invention discloses a spectrum resource allocation method based on auction. The spectrum resource allocation method based on the auction uses two layers of auction models, wherein the first layer auction is based on a main user and a relay node, and the second layer is between the relay node and a secondary user. The spectrum resource allocation method based on the auction comprises the following steps: the second layer auction is performed virtually; the relay node collects the budget, the quotation, and the demand for resources of the secondary user; the amount of collected money is calculated; the secondary users are randomly divided into two sets, and the victorious secondary user set is confirmed firstly; the relay node competes for the main user spectrum resource after collecting the amount of the secondary user; the main user submits the price of the spectrum resource, and the relay node submits the budget for the resource, so that a two division graph is set up, and the difference of the price and the budget is used as the weight of the two division graph; the maximum weighted matching algorithm is used for the two division graph, and the VCG auction algorithm is used to calculate the final payment amount of the relay node; and after the relay node competes for the main user successfully, the second layer auction is carried out again to assign the competitive spectrum resources to the final victorious secondary user.

Description

technical field [0001] The invention relates to the technical field of mobile cloud computing, in particular to an auction-based spectrum resource allocation method. Background technique [0002] Cloud Computing: As an Internet-based computing method, cloud computing can provide computers and other devices with the required resources through shared hardware and software resources and information. It can be allocated on demand according to the needs of users. The core idea is to manage and schedule the computing resources connected to the network in a unified manner. [0003] Mobile cloud computing: Mobile cloud computing involves cloud computing, mobile computing and wireless networks. It can use wireless networks to connect mobile devices or other smart devices in a wireless network environment to achieve resource sharing and data transmission. [0004] Spectrum: With the rapid development of wireless communication technology, wireless network communication devices such as...

Problems solved by technology

[0007] The existing resource auction methods fail to provide an effective incentive mechanism. Many resource auction methods only consider that a single resource can only be used by one user, or fail to consider the joining of relay nodes. In this case, it may cause The following questions:

[0008] Only a single user uses idle spectrum resources, and a single user may not be able to fully use all resources, which will also cause a waste of resources, and will cause a high cost for a single user;

[0009] Failure to consider relay nodes will reduce the data transmission rate and indirectly affect the utilization of spectrum resources;

[0010] Poor performance in terms of maximizing the overall revenue, unable to comprehensively consider the economic benefits of all participants in the auction
