Secondary User Sensing Time Optimization in Sensing-Transmission Scheduling for Dynamic Spectrum Access in Cognitive Radio
Corresponding Author: Inderdeep Kaur Aulakh University Institute of Engineering and Technology, Panjab University, Chandigarh, India Email: [email protected] Abstract: The constraint of limited frequency spectrum for wireless communication is very daunting. The radio spectrum licensed to permanent users is wasted at times when not used continuously. Cognitive radio technology involves a ch...
متن کاملSecure Collaborative Spectrum Sensing in the Presence of Primary User Emulation Attack in Cognitive Radio Networks
Collaborative Spectrum Sensing (CSS) is an effective approach to improve the detection performance in Cognitive Radio (CR) networks. Inherent characteristics of the CR have imposed some additional security threats to the networks. One of the common threats is Primary User Emulation Attack (PUEA). In PUEA, some malicious users try to imitate primary signal characteristics and defraud the CR user...

متن کاملOptimization of cooperative spectrum sensing with sensing user selection in cognitive radio networks
Cooperative spectrum sensing (CSS) can improve the spectrum sensing performance by introducing spatial diversity in cognitive radio networks (CRNs). However, such cooperation also introduces the delay for reporting sensing data. Conventional cooperation scheme assumes that the cooperative secondary users (SUs) report their local sensing data to the fusion center sequentially. This causes the re...
متن کاملSensing Strategies for Opportunistic Spectrum Access in Cognitive Radio Networks
SENSING STRATEGIES FOR OPPORTUNISTIC SPECTRUM ACCESS IN COGNITIVE RADIO NETWORKS Nazanin Rastegardoost George Mason University, 2015 Thesis Director: Dr. Bijan Jabbari In this thesis, we address an important issue in opportunistic spectrum sensing, dealing with medium access strategies in decentralized cognitive radio networks. Specifically, our focus is on MAC layer channel selection schemes f...
