Opportunity sharing-based wireless virtual resource allocation method

Abstract

The invention relates to the technical field of mobile and wireless networks, and provides an opportunity sharing-based wireless virtual resource allocation method. The method comprises the following steps: determining the total quantity of resources in a physical network; determining the quantity of virtual networks and the resource demands including baseline demands, elastic demands and the probabilities of the elastic demands of each virtual network; determining a price needing to be paid by each virtual network, wherein the price is a concave function relating to the resource demands; setting constraint conditions including conditions that the total quantity of resources allocated by the virtual networks does not surpass the total quantity of resources in the networks, one resource is occupied by one baseline demand at most, and the conflict probability under the condition that the elastic demands of different virtual networks occupy the same resource does not surpass a preset conflict threshold; under the constraint conditions, computing a resource allocation way by means of which the total gain of the physical network is maximized through an algorithm. By adopting the method, the utilization ratio and application gain of resources can be increased, customization of network services is realized, and the service quality is improved.

Description

technical field [0001] The invention relates to the technical field of mobile and wireless networks, in particular to a method for allocating wireless virtualization resources based on opportunity sharing. Background technique [0002] Mobile and wireless networks have made remarkable achievements in the past few decades and have become one of the most far-reaching technologies that affect people's lives. However, with the explosive growth of people's demand for mobile data volume in recent years, existing mobile and wireless networks have encountered several thorny problems and bottlenecks. First, several well-known operators said that spectrum resources have become extremely scarce, making it difficult to meet the growing demand for mobile data. However, in practice, there are a lot of idle mobile resources around users, but they are not efficiently utilized, which causes a lot of spectrum resources to be wasted. Second, the growing prosperity of the mobile Internet has ...

Problems solved by technology

Traditional resource allocation methods assume that the demand of the resource demander is fixed. However, in the wireless network virtualization environment, the resources applied for by the virtual network are often applied according to the peak demand, that is, the applied resources are not used most of the time. As a result, resources are wasted, which restricts the utilization rate of resources and the improvement of use income.
