基于簇的分布式巷道频谱合作感知

Distributed Tunnel Spectrum Cooperation Sensing Based on the Cluster

针对煤矿巷道岔道多、巷道长的无线通信环境特点,提出一种基于簇的分布式合作频谱感知技术的算法,该算法选取每个巷道分支中SNR最大的节点作为簇头,簇间用分布式合作方式进行频谱感知。仿真结果表明,该算法不仅可以提高低信噪比下的检测概率,而且可以改善合作频谱感知的安全性。

For the wireless communication environment characteristics of many turnouts and long tunnels in coal mine. This paper pro- poses a kind of distributed cooperative spectrum sensing algorithm based on clusters. This algorithm selects the biggest node of SNR in each tunnel branch as the head, and spectrum sensing is done anmong clusters in a distributed cooperative way. The simulation results show that this algorithm not only can enhance the detected probability of low SNR, but also can improve the safety of cooperative spee- trnm sensing.
