Abstract

With the explosion of demand for wireless communication services, scarcity of spectrum poses a great challenge to wireless networking. However, recent field measurements show that a significant percentage of spectrum is under-utilized. To address this problem, the research community introduced the concept of real-time secondary markets, where licensees are allowed to temporarily lease the spectrum unused by the primary users to secondary users. To support this new service, an Authentication, Authorization, and Accounting (AAA) mechanism must be in place to enable the licensees and secondary users to trade spectrum in a real-time manner. In this paper, we present an AAA system architecture, and propose a set of mechanisms to authenticate and authorize secondary users, synchronize multiple secondary devices, and manage real-time secondary market services. © 2005 IEEE.
