[0030] 1 system model

[0031] Wireless network virtualization architecture such as figure 1 As shown, in the actual scenario, only one physical access point connects all users, but in a virtualized environment, multiple different virtual access points coexist on the same physical access point to provide services for their respective users , different virtual access points belong to different SPs. SPs are responsible for authorizing users' access, providing users with ideal resources and corresponding prices, and providing quotations to NO to compete for resources. The NO is responsible for managing the wireless access network, and can obtain the status information of all channels, the identity of SPs and users, and perform auctions according to the resource requirements of SPs to reallocate resources. In summary, in our model, the problem of how to efficiently allocate subcarrier downlink power to all SPs and users on a single physical access point is considered.

Abstract

The invention requests protection of a resource allocation method in wireless network virtualization, and uses a buying and selling model to solve the game problem between SPs and MUEs. Then SP proposes its own utility function to NO according to the above-mentioned expected power and its initial allocated power, and then NO redistributes the power among SPs by building an auction model. We prove that there is a Steinberg equilibrium in the buy-sell model. In the auction model, we use the McPhee mechanism. SPs provide their real utility function to NO, and then NO redistributes resources among SPs. The invention makes full use of physical resources and improves the utilization rate of infrastructure resources.

Description

technical field [0001] The present invention is a research on resource allocation algorithm in wireless network virtualization, which belongs to the technical field of network virtualization, and in particular involves multiple network service providers sharing an infrastructure, and under the control of network operators, network resources Research on the allocation and redistribution of network resources among network service providers through auction mechanism. Background technique [0002] With the rapid development of information and communication technology, people's requirements for the Internet are getting higher and higher. The current Internet gradually has many disadvantages, which hinder the transformation to the next generation network. Network virtualization not only solves the "rigidity" problem of the Internet and the controversy over network architecture, but also provides an experimental platform and technical support for future networks. [0003] In the ...
