The Future Of Spectrum Sensing

Even though databases are currently favored in spectrum sharing scenarios, sensing is still needed. Spectrum sensing has a future in several existing and novel situations and applications. Those include crisis situations, local and indoor networks like wireless local area networks (WLAN) and battery-oriented applications like future intelligent Internet of Things (IoT). In this paper, the future of spectrum sensing is covered. Spectrum sensing properties are discussed and a short review about the most recent spectrum sensing methods is presented. The focus of this paper is on analyzing and defining conditions when spectrum sensing is a reasonable and justified choice. Our analysis showed that there are a lot of situations and applications when spectrum sensing is a practical and cost-effective choice. The advantages and disadvantages of sensing have to be in balance. The situation, application and used sensing method including their restrictions, requirements and needs have to be taken into account.
