摘要
针对认知无线电网络、频谱监测等领域对宽频段频谱感知的需求,基于无线传感器网络的特点,提出了一种面向频谱感知的传感器网络设计方案,包括分簇的网络结构、分频段的协作感知机制以及感知结果的协作处理机制,分析了实现这种方案的关键技术,为利用传感器网络进行宽频带协作频谱感知提供了一种可选的方案。
Resorting to the requirement of cognitive radio network and spectrum monitoring in wide-band spectrum sensing, a framework of wireless sensor network for spectrum sensing is proposed. The framework includes clustered network structure, frequency division based cooperative sensing and cooperative sensing result processing scheme. Furthermore, the key technologies of the implementation of this framework are analyzed.
