基于传感器网络的异常检测算法研究

Research on Outlier Detection Algorithm Based on Sensor Network

本文首先研究了传感器网络数据流中滑动窗口的数据分布估计,在数据分布估计的基础上,进一步研究了基于距离的在线异常检测方法——D3算法,并提出了改进方案;最后给出了下一步工作方向。

This paper firstly studies data distribution estimation in a sliding window of network data stream Then distance - based outlier detection algorism - D3 based on the data distribution estimation is studied. Finally ,improvements of D3 algorism are provided and the next step directions are given.
