Performance analysis of spectrum sharing mechanisms in cognitive radio networks
In this article, a non-preemptive (NP) mechanism is proposed to improve the quality-of-service (QoS) of secondary users (SUs) in joint leasing and sensing-based cognitive radio networks (CRNs). In this spectrum-sharing mechanism, a primary user (PU) could not forcibly terminate a SU with ongoing transmission. Both the typical preemptive and the proposed NP mechanisms are modeled by multi-dimens...
متن کاملPerformance Analysis of Cognitive Radio Networks under Spectrum Sharing and Security Constraints
The cognitive radio network (CRN) concept has been proposed asa solution to the growing demand and underutilization of the radiospectrum. To improve the radio spectrum utilization, CRN technologyallows the coexistence of licensed and unlicensed systems over the samespectrum. In an underlay spectrum sharing system, secondary users(SUs) transmit simultaneously with the pri...
متن کاملPerformance Study of Interweave Spectrum Sharing Method in Cognitive Radio
www.ijarcet.org 1866 Abstract— Spectrum scarcity is one of the most critical recent problems in the field of wireless communication. One of the promising approaches to resolve this issue is the use of Cognitive Radio technique. CR technique is performed by Secondary User (SU) to utilize the spectrums more efficiently. SU transmission mode can be broadly divided into two modes: interference av...
متن کاملPerformance Analysis of Cognitive Radio Networks with Dynamic Spectrum Access
Intelligence is a very important characteristic for cognitive radios networks. Design of cognitive engine and application of artificial intelligence techniques are key to the implementation of this characteristic. In this paper, we have proposed a system model of cognitive network which is based on the concept of multiple cognitive terminals sharing the same set of channels. The effect of numbe...
متن کاملPerformance Analysis of Spectrum Sensing Techniques for Cognitive Radio Networks
Spectrum sensing is a key element for cognitive radio and is process of obtaining awareness about the radio spectrum in order to detect the presence of other users. In this paper we study the performance of different spectrum sensing techniques in terms of detection performance and required SNR, based on theoretical expressions. Keywordscognitive radio; spectrum sensing; energy detection;matced...
