Research On Heterogeneous Spectrum Unidirectional Auction Technology In Wireless Communication

As a scarce resource, how to allocate and utilize the spectrum resource is very important and critical. Spectrum resource allocation method will determine who can get a license at what price.In recent years, with the soaring development of various wireless communication technologies, the mobile broadband demand for limited spectrum resource is experiencing a rapid growth. Unfortunately, majority of the spectrum resources have been allocated through long-term and regional leases without carefully planning, while large number of new applicants are in shortage of the desired spectrum. To tackle this issue, a truthful auction framework is proposed to solve the heterogeneous spectrum trading in this work. The given mechanism provides enough incentives to encourage the existing spectrum holders(a.k.a primary users, sellers) to sell the underutilized spectrum resources to the new applicants(a.k.a secondary users, buyers), which can greatly alleviate the existing “spectrum crisis”. A high efficient greedy spectrum allocation method is adopted in the proposed mechanism. Our goal is to design truthful auction mechanism that maximizes the overall social efficiency of new users. In order to improve the spectrum utilization, we allocate each spectrum channel to a set of buyers without interference. Further, to achieve the truthfulness(or strategyproofness), a bid-independent payment calculation method is proposed. Moreover, via simulation, we show the effectiveness of the proposed algorithm.
