The increasing spectrum demand from wireless applications cannot be satisfied with existing fixed spectrum allocation techniques. To provide dynamic spectrum access, auction based spectrum trading has received considerable attention. In spectrum trading, licensed users rent their unused spectrum to unlicensed users in exchange for money. The availability of unused spectrum depends on the usage pattern of licensed users and varies over time, frequency, and spatial domain. Unlicensed users can bid for this spectrum according to their needs which again vary by time and location. Thus, the auction scenario has to deal with the dynamic user demand and dynamic spectrum supply. Existing research on spectrum trading consider either a static auction environment or at most one side of the dynamics of the auction environment. Therefore, for improving spectrum unitization, it is critical to consider an auction scenario where bidders with heterogeneous demand arrive dynamically and bid for dynamically available spectrum units.This project studies a dynamic auction framework and undertakes the development of auction rules and regulations designed to achieve an efficient spectrum allocation. The study consists of four major components. (1) Developing the dynamic auction framework with dynamic arrival of users with variable lifetime and dynamic spectrum supply. (2) Tackling the design challenges associated with the diversity in demand and supply in terms of units and duration and devising a truthful auction mechanism. (3) Designing a generic auction framework to fit the auction rules and regulations and define the communication method using a secure communication protocol. (4) Developing a testbed to implement, experiment and validate the auction framework. This research will enhance radio spectrum sharing and utilization, providing more spectrum opportunities for existing and new applications. This project provides interdisciplinary research opportunities for graduate students working on the proposed research. This project incorporates research results into courses and to recruit students from underrepresented backgrounds.

现有的固定频谱分配技术无法满足无线应用日益增长的频谱需求。为了提供动态频谱访问，基于拍卖的频谱交易受到了相当多的关注。在频谱交易中，获得许可的用户将未使用的频谱出租给未获得许可的用户以换取金钱。未使用频谱的可用性取决于许可用户的使用模式，并且随时间、频率和空间域而变化。未经许可的用户可以根据自己的需求竞标该频谱，这些需求也因时间和地点而异。因此，拍卖场景必须处理动态的用户需求和动态的频谱供应。现有的频谱交易研究要么考虑静态拍卖环境，要么最多考虑拍卖环境动态的一方面。因此，为了提高频谱单元化，考虑拍卖场景至关重要，其中具有异构需求的投标人动态到达并竞标动态可用的频谱单元。该项目研究动态拍卖框架，并负责制定旨在实现高效频谱分配的拍卖规则和条例。该研究由四个主要部分组成。 (1) 开发具有可变生命周期和动态频谱供应的用户动态到达的动态拍卖框架。 （2）解决与需求和供应在单位和期限方面的多样性相关的设计挑战，并设计真实的拍卖机制。 (3)设计通用拍卖框架以适应拍卖规则和规定，并使用安全通信协议定义通信方法。 (4) 开发一个测试平台来实施、实验和验证拍卖框架。这项研究将增强无线电频谱共享和利用，为现有和新应用提供更多频谱机会。该项目为从事拟议研究的研究生提供了跨学科研究机会。该项目将研究成果纳入课程中，并招收来自弱势背景的学生。
