An application-oriented spectrum sharing architecture
© 2002-2012 IEEE. The current opportunistic spectrum access architecture suffers from several technical barriers. Capitalizing on recent spectrum policy evolution and technology advances, we propose an application-oriented spectrum sharing architecture, termed on-demand spectrum access, to eliminate the barriers bothering the opportunistic spectrum access architecture. We consider a spectrum service provider that has a mesh infrastructure network and offers on-demand spectrum services to users. The users can dynamically set up application-oriented virtual topologies to carry out specific applications such as video conferences. We develop an efficient online spectrum service provision algorithm, termed Provision based on Onion Subsetting. The time complexity and the correctness are analyzed. We evaluate the performance of the on-demand spectrum access architecture under the provision algorithm through simulations.
