Cooperative spectrum sensing and Detection

by Nishant Dev Khaira, Prateek Bhadauria
"... Abstract—Spectrum sensing is required for better utilization of spectrum and preventing interference with licensed users. However, detection performance in practice is often compromised with multipath fading, shadowing and receiver uncertainty issues. To mitigate the impact of these issues, cooperat ..."
Abstract - Add to MetaCart
, cooperative spectrum sensing has been shown to be an effective method to improve the detection performance by exploiting spatial diversity. While cooperative gain such as improved detection performance and relaxed sensitivity requirement can be obtained, cooperative sensing can incur cooperation overhead

IN-NETWORK COOPERATIVE SPECTRUM SENSING

by Mehmet E. Yildiz, Tuncer C. Aysal, Kenneth E. Barner
"... This paper proposes a distributed average consensus algorithm in order to solve the cooperative spectrum sensing task without a cognitive base station. The proposed consensus algorithm converges to the optimal decision statistic in the limit. Since in practice the iteration number has to be finite, ..."

Defending Against Cooperative Attacks in Cooperative Spectrum Sensing

by Zhengrui Qin, Student Member, Qun Li, Senior Member, George Hsieh
"... Abstract—Accurate spectrum sensing is important in cognitive radio networks. False sensing results in either waste of spectrum or harmful interference to primary users. To improve accuracy, cooperative spectrum sensing, in which a set of secondary users cooperatively sense the presence of the primar ..."

Sensor Selection for Cooperative Spectrum Sensing

by Hugo Tullberg, Jonas Kron - in Proce. IEEE Symp. on New Frontiers in Dynamic Spectrum Access Networks (DySPAN , 2008
"... Abstract—This article considers spectrum-on-demand in a cellular system. A communication system that wants to access spectrum to which it does not own a license must perform spectrum sensing to identify spectrum opportunities, and to guarantee that it does not cause unacceptable interference to the ..."

Cooperative Spectrum Sensing Strategies with Multiple Relays

by Qian Chen, Mehul Motani, Wai-choong Wong
"... Abstract—In this paper, we consider the cooperative spectrum sensing problem for a cognitive radio (CR) mesh network. Based on multiple relay model, we propose two cooperative spectrum sensing strategies called amplify-and-relay (AR) and detect-and-relay (DR), and also derive the closed-form express ..."

Cooperative Spectrum Sensing for Cognitive Radios under

by Chunhua Sun, Wei Zhang, Khaled Ben Letaief - Bandwidth Constraints,” IEEE Wireless Communications and Networking Conference , 2007
"... Abstract — In cognitive radio systems, cooperative spectrum sensing is conducted among the cognitive users so as to detect the primary user accurately. However, when the number of cognitive users tends to be very large, the bandwidth for reporting their sensing results to the common receiver will be ..."
