Performance Analysis of CSMA in Cognitive Radio Network with Random Residence Time of SUs: 《International Journal of Communications, Network and System Sciences》2017年第8期186-195,共10页Dongbi Zhu Yang Chen Yihu Xu; We consider a carrier sense multiple access (CSMA) in an unslotted cognitive radio network with random residence time. In this system, if an arriving secondary user (SU) does not find any idle channels, then the SU ei...; 关键词：COGNITIVE RADIO Network CSMA CTMC RESIDENCE Time

Self-Coexistence Strategy in Heterogeneous Cognitive Radio Networks: 《International Journal of Communications, Network and System Sciences》2017年第5期311-323,共13页Qiang Zhang Yong Zhang Mei Song Dawei Dang; Different from general cognitive wireless networks, there is no centralized scheduling and management infrastructure among heterogeneous cognitive networks. Multiple cells may operate in the same vicinity resulting in...; 关键词：HETEROGENEOUS COGNITIVE Networks Self-Coexisting FAIRNESS Game Theory

Performance Evaluation of Spectrum Detection in Cognitive Radio Network: 《International Journal of Communications, Network and System Sciences》2014年第11期485-496,共12页Shubhangi Mahamuni Vivekanand Mishra; In mobility management, detection of spectrum hole plays very important role for doing spectrum handoff mechanism. Operation of the cognitive radio depends on the spectrum sensing which is the most important task in c...; 关键词：COGNITIVE RADIO SPECTRUM SENSING SPECTRUM HANDOFF SPECTRUM HANDOFF MINIMIZATION

Analysis of Cognitive Radio Enabled Flooding in Opportunistic Networks: 《International Journal of Communications, Network and System Sciences》2014年第7期212-222,共11页Muhammad Arshad Islam Marcel Waldvogel; Epidemic routing (Flooding) is considered as a simple routing protocol for opportunistic networks where the participants attempt to transmit whatever information they have to everyone who does not already have that in...; 关键词：OPPORTUNISTIC NETWORKS Delay TOLERANT NETWORKS FLOODING COGNITIVE Radio Simulation
