However, this division is long-term, and the space-time dimension is fixed. So far, the waste phenomenon is very serious. The utilization rate of many frequency bands is extremely low, but they cannot be used in places where frequency bands are scarce, which seriously restricts the development of wireless networks.

Embodiment Construction

[0030] According to the wireless network frequency band allocation method of the present invention, it can be directly applied in areas with uneven frequency band allocation. First of all, the primary user has free frequency bands that can be used by others to improve frequency band utilization and increase revenue, and secondly, there are multiple secondary users to purchase frequency bands. What needs to be considered here is the situation that the supply exceeds the demand, because when the frequency band is sufficient, each user can meet the purchase demand without scheduling. So here we only consider the situation when the frequency band is insufficient, and design a fair frequency band sales mechanism for this situation, fully consider the sub-user psychology in reality, form the optimal combination in the form of alliance, and conduct the frequency band in the form of combination Joint purchase is more realistic. The method of the invention builds a process model of th...

Abstract

The present invention proposes a wireless network frequency band allocation method based on Shapley algorithm, including: S1 announcing the idle wireless network frequency band number, the lowest sales threshold of the frequency band and the lowest sales price; S2 the frequency band number declared by each user; S3 Calculate the sub-user combination that meets the minimum sales threshold of the frequency band; S4 classifies the sub-users; S5 calculates the Shapley value of each multiple-time user; S6 calculates the expected payment; S7 Determines the multiple-time users in all the reserved sub-user combinations According to whether the calculated estimated payment has been fixed in the reserved sub-user combination, if yes, go to step S8, if not, go to step S5, or step S5 has been executed a preset number of times, go to step S8; S8 The secondary user combination is open for auction; the secondary user combination with the highest S9 bid total wins. The invention can calculate the optimal frequency band allocation mode to meet the needs of secondary users.

Description

technical field [0001] The invention belongs to the technical field of wireless network frequency band allocation, and in particular relates to a wireless network frequency band allocation method based on the Shapley algorithm. Background technique [0002] It has always been the government regulatory bureau that controls the use of wireless network frequency bands. According to the peak state of use, the frequency band is divided into equal-sized blocks, called channels, for fixed services, such as the frequency band for TV reception. However, this division is long-term, and the space-time dimension is fixed. So far, the waste phenomenon is very serious. The utilization rate of many frequency bands is extremely low, but they cannot be used in places where frequency bands are scarce, which seriously restricts the development of wireless networks. [0003] Based on this situation, a phenomenon occurs that primary users PU (PrimaryUsers) wish to sell the remaining idle frequen...
