Embodiment Construction

[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 provides a resource allocation method for virtualization of a wireless network. The resource allocation method comprises the following steps of utilizing a buy and sell model to solve a game problem between SPs (service provider) and MUEs (multiuser); then, according to the expected power and the self initial allocated power, enabling the SP to propose a self utility function to a NO (network operator); enabling the NO to reallocate the power between the SPs by building an auction model. In the buy and sell model, the Steinberger balance exists; in the auction model, a McPhee mechanism is utilized, the SPs provide the self real utility functions to the NO, and the NO reallocates the resources between the SPs. The method has the advantages that the physical resources are sufficiently utilized, and the resource utilization rate of infrastructures is improved.

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 ...
