Performance Enhancement of Asynchronous Cooperative Spectrum Sensing
نویسنده
چکیده
In cognitive radio networks, the users are supposed to perform spectrum sensing with mush more accuracy to detect the more and more users. But in practice due to fading, shadowing etc., a long observation period of time is needed to make decisions based on detection which results in degradation of sensing performance. In this paper, we presented a new approach called Cuckoo Search for asynchronous cooperative spectrum sensing which results in enhanced sensing performance. Simulation results show that the detection time is reduced without sensing performance degradation compared to Asynchronous cooperative spectrum sensing (ACSS) and conventional cooperative spectrum sensing (CSS).
