A Sub-Optimal Low Complex Multiple Malicious Users' Detection Mechanism in a Cooperative Spectrum Sensing System
In cognitive radio based cooperative sensing systems, some secondary users are likely to act malicious. Such secondary users are called malicious users. An optimal application of Dixon's outlier detection scheme for detecting malicious users in a cognitive radio cooperative spectrum sensing system has recently been termed as the Sliding Window Dixon's test. The Sliding window Dixon's test appli...
متن کاملHistory based forward and feedback mechanism in cooperative spectrum sensing including malicious users in cognitive radio network
In cognitive radio communication, spectrum sensing plays a vital role in sensing the existence of the primary user (PU). The sensing performance is badly affected by fading and shadowing in case of single secondary user(SU). To overcome this issue, cooperative spectrum sensing (CSS) is proposed. Although the reliability of the system is improved with cooperation but existence of malicious user ...
متن کاملthe effects of cooperative versus individual directed reading thinking activities on students inferential and referential questions
two groups of students were assigned as experimental and control ones, and were given instruction on directed reading-thinking activities and after some treatment, they were post-tested. although the initial pre-test did not show any significant differences, the final post-test result revealed that the cooperative reading comprehension helped the experimental group. the cooperative students’...
15 صفحه اولA Fast Malicious User Detection Scheme Based on POMDP for Cooperative Spectrum Sensing in Cognitive Radio networks
Cooperative spectrum sensing (CSS) can improve spectrum sensing accuracy, but it can be injured due to potential attacks from malicious cognitive radio user who reports false sensing results to the fusion center (FC). Many researchers focus on reducing the effect of malicious users on the accuracy of spectrum sensing. A promising method to detect malicious users is to determine their abnormal s...
