集中式协作频谱检测在SimpliciTI网络中的应用
Application of centralized cooperative spectrum sensing in SimpliciTI network
摘要
Abstract
In this paper, a centralized cooperative frequency agility ( CoFA) based on the half⁃voting⁃rule coopera⁃tive spectrum sensing is proposed and applied in SimpliciTI protocol. SimpliciTI performs poorly in single node spectrum detection and there exist self⁃interference and hidden terminal problems. Therefore, CoFA is proposed to improve the anti⁃interference capability of wireless sensor networks. It has remarkable advantage in avoiding mul⁃tipath, shadow effect, hidden terminal problem, and solves the self⁃interference problem in traditional FA. Finally, the test showed that the method proposed could effectively solve the self⁃interference problem in former FA and in⁃creases 42% in average of the frequency sensing performance in SimpliciTI.关键词
