An efficient spectrum utilization via cognitive radio using fuzzy logic system for heterogeneous wireless networks

Abstract: At present, lots of works focus on spectrum allocation of wireless networks. In this paper, we proposed a Cognitive based spectrum access by opportunistically approach of Heterogeneous Wireless networks based on Fuzzy Logic system. The Cognitive Radio is a technology where a network or a wireless system changes its environment parameters to communicate efficiently by avoiding the interference with the users. By applying FLS (Fuzzy Logic System), the available spectrum utilization is effectively utilized with t… Show more

“…Bu yüzden spektrum paylaşımı, ortam erişim kontrol protokolünün fonksiyonlarıyla daha yakından ilişkilidir [6]. Birincil kullanıcılarla ikincil kullanıcıların aynı spektrumda olması ve geniş bir frekans aralığındaki kullanılabilir spektrum bantları gibi bilişsel radyo ağlarının farklı özellikleri spektrum paylaşımı için çeşitli zorluklara yol açmaktadır.…”

“…In [5] an approach using Fuzzy Logic System (FLS) to control the spectrum access is proposed which detects the effective spectrum access for secondary users via cognitive radio. In [6], [7] a decentralized architecture was considered, as solution to problem of the spectrum handoff decision, channel selection and channel estimation on the way how a SU makes this decision based on the information available from the spectrum sensing. To trigger spectrum handoff a simple and less complex fuzzy-based approach is suggested, which guarantees quick decisions so that SUs can autonomously and automatically make the decision to change its frequency channel.…”
