Problems solved by technology

If the existing homogeneous spectrum auction method is simply extended to the heterogeneous spectrum auction method, the efficiency of spectrum reuse will be low, and the authenticity of the auction cannot be guaranteed

Embodiment 1

[0024] Assume there are three frequency spectrums A, B, and C, and the center frequencies are arranged as A

[0025] like figure 1 As shown, an authentic double auction method for heterogeneous spectrum, the implementation steps of this method are as follows:

[0026] S1. Arrange the spectrum segments to be auctioned in ascending or descending order according to the height of the center frequency, and form all spectrums into a spectrum set. The auctioneer sets a spectrum base price for each spectrum segment, which can be arranged in ascending or descending order. This is in ascending order For example, the composition spectrum set is {A, B, C}, assuming that the auctioneer sets the spectrum reserve prices for A, B, and C as 8, 4, and 6 respectively;

[0027] S2. Receive the bid vector submitted by the bidder. The length of the bid vector is equa...

Embodiment 2

[0037] The difference from Embodiment 1 is that finding a pending independent set according to the set search conditions in S7 as an independent set includes: selecting the pending independent set with the highest group bid as an independent set, if there is more than one pending independent set with the highest group bid, Then randomly select one of them as an independent set.

[0038] The implementation process from S4 to S8 is as follows: the initial spectrum set is {A, B, C}, and the virtual auction node set is {a1, a2, b, c, d1, d2, e}, so the spectrum set and virtual auction node Whether the sets are not empty, take A to create a spectrum interference graph, and the spectrum set becomes {B, C}, assuming that a, b and c are interference relationships, c and d are interference relationships, and d and e are interference relationships; then The virtual auction node is inserted, and the spectrum interference diagram after the virtual auction node is inserted is as follows ...

Embodiment 3

[0040] The difference with Embodiment 1 is that finding a pending independent set according to the set search conditions in 7 as an independent set includes: calculating the number of winners whose virtual bidding nodes in the pending independent set belong to the previous spectrum; The auction node belongs to the undetermined independent set with the largest number of winners of the previous spectrum as the independent set. If there is more than one undetermined independent set, one of them is randomly selected as the independent set.

[0041] The implementation process from S4 to S8 is as follows: the initial spectrum set is {A, B, C}, and the virtual auction node set is {a1, a2, b, c, d1, d2, e}, so the spectrum set and virtual auction node Whether the sets are not empty, take A to create a spectrum interference graph, and the spectrum set becomes {B, C}, assuming that a, b and c are interference relationships, c and d are interference relationships, and d and e are interfer...

Abstract

Disclosed is an authenticity dual auction method targeting at heterogeneous frequency spectra. The method includes the following steps: arraying different sections of to-be-auctioned frequency spectra; receiving bid vectors submitted by bidders; establishing bidding nodes and virtual bidding nodes; judging whether both of a frequency spectrum set and a virtual auction node set are nonempty, and if so, taking out a frequency spectrum which is ranked foremost and establishing a frequency spectrum interference figure for the frequency spectrum, or else stopping the process; and searching for an independent set, in which all virtual bidding nodes except a virtual bidding node of a lowest offer obtain the section of frequency spectrum and apportioning a group bid of the independent set by obtainers. In the authenticity dual auction method targeting at the heterogeneous frequency spectra, the bidders submit the bid vectors so that it can be ensured that the bidders can offer different valuations for different frequency spectra so as to ensure that a valuation of a single section of frequency spectrum is more reasonable. Different sections of frequency spectra establish frequency spectrum interference figures according to respective frequencies so that an absolute non-interference relation between non-interference parties is ensured and a multiplex ratio of the frequency spectra can also be maximized.

Description

technical field [0001] The invention relates to the technical field of wireless communication, in particular to an authentic double auction method for heterogeneous spectrum. Background technique [0002] With the rapid development of communication technologies and wireless networks, wireless operators have increasing demands on spectrum resources. To this end, relevant government departments in various countries have plans to open more spectrum to wireless operators. For example, the US Federal Communications Commission (FCC) plans to withdraw the licenses of existing spectrum occupants and re-auction spectrum to wireless operators. Auction is one of the means to achieve efficient use of spectrum. Through auction bidding, spectrum resources can be obtained by the wireless operator who bids the highest for the spectrum and can best realize the value of the spectrum. [0003] Existing spectrum auction methods first focus on the characteristics that spectrum can be reused....
