摘要

<FONT face=Verdana>本文提出一种基于伸展树的事件区域容错检测算法

该算法在构成的分布式融合树上实施

由多元回归方程对事件发生的可能性进行评估

利用被检测事件的时空相关性

使得在缺少传感节点的区域

Sink节点也可以获得事件发生的状态信息.理论分析及仿真结果表明

即使节点发生故障的概率较高

提出的检测算法也能获得较高的精度和较小的误判率

表明在事件区域容错检测中应用该方法是可行的.

Abstract

<FONT face=Verdana>This paper investigates a kind of algorithm called splay tree based event region faulttolerant detection algorithm (STERD) for Wireless Sensor Networks (WSNs).Since the algorithm is implemented over a splay tree in a distributed manner

a polynomial regression addressed these problems of event region detection by having a splay tree of sensor nodes.The sink can get attribute values in regions devoid of sensor nodes for attribute values that show smooth spatiotemporal correlation.Theoretical analysis and simulation results indicate that the proposed STERD can attractively obtain the high event region detection accuracy and considerably reduce the false alarm probability even when fault nodes exist.
