摘要

基于单阈值的监测算法降低了警报的准确率，因此研究基于双阈值的监测方法，即带有概率保证的约束违反的监测具有重要意义.首先，基于监测结果的概率阈值语义，研究了节点的双阈值监测问题.其次，给出了感知数据大于监测阈值的概率的紧上界，提出了基于双阈值的分布式监测算法.第三，给出了根据精度要求确定优化样本容量的数学方法，提出了基于抽样的近似簇监测算法.理论分析和实验结果验证了提出的监测算法的高效性.

Abstract

Sole threshold based monitoring algorithms bring down the accuracy of alarm

hence researching on dual threshold based monitoring technique

that is

constraint violation monitoring with probability guarantee has significant meanings.Firstly

according to the semantics of probability threshold on the monitoring result

dual threshold monitoring of sensor node was investigated.Secondly

a tight upper bound of the probability of the sensing data larger than monitoring threshold was given

and dual threshold based distributed monitoring algorithm was proposed.Thirdly

based on the given accuracy requirement

a mathematical method to determine an optimal sample was provided.A sampling based approximate cluster monitoring algorithm was proposed.The theoretical analysis and performance evaluation demonstrate the efficiency of the proposed algorithms.
