Abstract
This Chapter introduces the cognitive radio network as one of the most promising technologies for the immediate and very near future. It explores its rich history and establishes that the radio-frequency spectrum is the most important base in the overall cognitive radio network scheme. The recently-proposed concept of dynamic spectrum access and allocation is portrayed as the preferred mechanism for sharing and administering the spectrum, especially for most newly-emerging technologies, and particularly for the cognitive radio network. Importantly, the Chapter sets the stage for ongoing discussions on the recent developments in the design and implementation of modern cognitive radio networks.
