Appropriate Channel Selection for Data Transmission in Cognitive Radio Networks
Minal S. Moon, Veena A. Gulhane · Procedia Computer Science · 2016
Cognitive radio is a wireless technology that provides solution to meet scarcity of radio spectrum. Here primary channel sensing and selection of appropriate vacant channel for communication by secondary users are two important tasks. In this paper various primary channel selection techniques has been studied. This paper also presents an idea to design a contention based channel selection algorithm using a structure called Preferable Channel List (PCL) where receiver plays a dominating role in channel selection process. The algorithm will avoid collision and perform RTS-CTS contention for data transmission.
