Paper Abstract

In this paper, we present a brief overview on the recent development of the dynamical spectrum access (DSA) techniques, focusing on the following areas: characteristics of the available bandwidth of the primary users, sensing technologies and sensing intervals to detect white spaces, spectrum allocation and management, reliability of the secondary user, tradeoff between spectrum/performance gain versus additional overhead used in implementing DSA, and cross layer optimization in spectrum sharing. Some of tradeoff studies are presented in terms of price of anarchy, which is defined as the price that a decentralized system should pay for not being coordinated. We will also discuss some of the open issues in deploying DSA.
