基于轮询策略的信任度合作感知
he study of cooperation spectrum sensing based on poll strategy and node’s trust
本文在对认知无线电技术中的合作感知技术进行了研究,通过分析传统的合作感知技术的优缺点,针对基于簇结构的认知网络,提出了基于轮询策略的多节点信任度合作检测方法。现有合作感知算法忽视各感知节点所处的环境差异所导致的各节点检测可靠性不同,往往导致合作检测结果的性能下降,通过引入信任度因子,能够有效提升合作感知的性能。在簇结构的认知网络中,节点的地理位置和作用存在重叠现象,使用轮询的策略进行合作感知,能够提升认知网络的生存时间和减少节点间的干扰。本文以能量检测器为例,进行了算法的仿真对比,证明了基于D-S证据理论的轮询融合感知在性能上优于现有的多节点频谱感知算法。
In this paper, we study the cooperation spectrum sensing technology of Cognitive Radio. We declare a cooperation spectrum sensing based on the nodes’ trust situation to solve that the traditional ways ignore the modes’ individual environment in the whole wireless environment. Because the different nodes in different places will be affected by the different wireless situation, leading to the individual sensing result. And based on the cognitive radio cluster network structure, we deploy a poll spectrum sensing to reduce the nodes’ energy consuming and the nodes’ lap over problem. We use the energy detection for the illustration , and the simulation proves that the D-S theory and poll spectrum sensing have better performance than the traditional cooperation spectrum sensing ways.
