Embodiment Construction

[0044] In this embodiment, a unidirectional heterogeneous spectrum allocation method based on differential privacy protection is applied to an auction system consisting of a spectrum provider and n spectrum bidders, and is performed in the following steps:

[0045] Step 1. Initialization:

[0046] Step 1.1, the spectrum provider participates in the auction process as an auctioneer, and the spectrum provider holds m segments of heterogeneous spectrum S=(s 1 ,s 2 ,...,s i ,...,s m ), where s i Represents the i-th segment spectrum, and has: s i ={D i , rad i}; where D i is the i-th spectrum s i description, rad i is the i-th spectrum s i interference radius. Before the auction starts, the spectrum provider first releases the description information of all spectrums to the spectrum bidders, so that the bidders can choose the spectrum they are interested in based on this information for bidding;

[0047] Step 1.2. At the beginning of the auction, each bidder will send i...

Abstract

The invention discloses a one-way heterogeneous spectrum allocation method based on differential privacy protection. The method comprises the following steps: 1, determining corresponding earnings andallocation schemes under a quoted price by pricing combinations of different spectrums; 2, protecting pricing by taking the total welfare value as an availability function through a differential privacy mechanism; and 3, determining a final price, and obtaining a corresponding distribution mode according to the finally selected price. According to the method, the problem of privacy leakage in traditional one-way heterogeneous spectrum auction can be remarkably solved, so that quotation information can be effectively protected, and meanwhile, efficient spectrum allocation is realized.

Description

technical field [0001] The invention relates to the technical field of wireless communication, in particular to a unidirectional heterogeneous frequency spectrum allocation method based on differential privacy protection. Background technique [0002] With the rapid development of the wireless communication industry, radio technology has had a profound impact on our lives. Especially in recent years, with the rapid development of smart mobile terminals and 4G and 5G technologies, the number of wireless communication equipment and services based on wireless communication has increased exponentially. However, radio spectrum, as an indispensable and precious resource in wireless communication, has been difficult to meet People's increasing wireless communication needs. Therefore, how to design a reasonable incentive mechanism to urge existing spectrum holders to provide frequency bands to new spectrum demanders, so as to improve spectrum utilization, has become an urgent need ...
