摘　　要：针对电磁频谱末端监测网中监测节点因外界或内在原因导致监测性能下降的问题，在分析和改进分布式Bayesian算法的基础上，提出一种具有较强容错能力的分布式协同检测算法。该算法充分利用监测数据的相关性和监测结果的一致性来纠正错误节点的错误检测结果，减少了错误节点对末端监测网性能的影响。对两种算法的分析和仿真，进一步证明了提出的算法能够在引入最少错误的同时纠正更多错误节点的错误检测结果，保证了电磁频谱末端监测网的性能，具有较强的容错能力。To mitigate impact on the performance of monitoring resulting from the internal and externalcauses of monitoring node in the ending electromagnetic spectrum monitoring sensor network, this paperproposes a novel distributed cooperative algorithm that has better fault-tolerance capability. The proposedalgorithm, using correlation in monitoring data and the coherence of monitoring results, could decreasesome errors resulted from sensor faults. Thus it could decrease impact on the performance of monitoringfrom some sensor faults. Analysis and simulation results show that the proposed algorithm can correctmore sensor faults with a few new errors so that it can ensure the performance of the ending electromag-netic spectrum monitoring networks and has better fault-tolerance capability.
