WebJun 27, 2014 · Spectrum efficiency and energy efficiency are two critical issues in designing wireless networks. Through dynamic spectrum access, cognitive radios can improve the spectrum efficiency and capacity of wireless networks. On the other hand radio frequency (RF) energy harvesting has emerged as a promising technique to supply energy to … WebThat is, the CR technique and dynamic spectrum access scheme are major solutions for increasing spectrum utilization in the cognitive radio sensor networks [15,27,28,29,30,31,32,33,34]. There have been several studies on spectrum access strategies in cognitive radio networks.
WebWith the rapid development of wireless communication technology, the low utilization of spectrum resources and the high demand for spectrum have always been an urgent and paradoxical problem to be resolved. In order to alleviate this conflict, cognitive radio technology has been proposed. In this paper, we propose a new method of distributed … WebIn dynamic spectrum access networks (also known as cognitive radio networks), Secondary Users can use spectrum white spaces (spectrum holes) that are not used by the Primary Users but must avoid interfering with active Primary Users. Such networks are key enablers to efficient use of the spectrum, and therefore, the FCC recently allowed ...
