Analysis on Deployment Parameters of Secondary Users in Cognitive Radio Networks

Free registration required

Executive Summary

Cognitive radio has emerged as an efficient approach to implement reuse of the licensed spectrums. How to appropriately deploy and construct the secondary network plays a rather important role. In this paper, a novel deployment scheme, which integrates the Radio Environment Map (REM) and Primary Exclusive Zones (PEZ) together, is proposed. The authors first illustrate secondary users' achievable region around one primary receiver based on protocol interference model. Then, they give the close-form of secondary users' density, which provides a standard for controlling number of secondary users in that achievable region.
