一种高效的传感器网络数据挖掘分布式数据抽取方法

An Efficient Distributed Data Extraction Method for Mining Sensor Networks Data

Azhar Mahmood, Shi Ke, Shaheen Khatoon

摘要:

传感器网络(SN)广泛部署在现实世界中的应用,产生大量的原始传感数据。数据采掘技术从这些应用中提取有用的知识是一个新兴的研究领域,由于其至关重要的,但仍然是一个挑战,有效地从传感器网络数据中发现知识。本文提出了一种分布式数据抽取(DDE)方法,通过应用基于规则的聚类和关联规则挖掘技术从传感器网络中抽取数据。从传感器发送到数据处理点的大量传感器读数可能丢失或损坏。DDE还从可用的传感器读数估计这些缺失值,而不是请求传感器节点重新发送丢失的读数。DDE还应用了数据压缩,能够在传输到sink时减少数据量。结果表明,我们提出的方法具有最大的数据准确性和有效的数据提取在整个网络的能源消耗。

英文摘要:

A wide range of Sensor Networks (SNs) are deployed in real world applications which generate large amount of raw sensory data. Data mining technique to extract useful knowledge from these applications is an emerging research area due to its crucial importance but still its a challenge to discover knowledge efficiently from the sensor network data. In this paper we proposed a Distributed Data Extraction (DDE) method to extract data from sensor networks by applying rules based clustering and association rule mining techniques. A significant amount of sensor readings sent from the sensors to the data processing point(s) may be lost or corrupted. DDE is also estimating these missing values from available sensor reading instead of requesting the sensor node to resend lost reading. DDE also apply data reduction which is able to reduce the data size while transmitting to sink. Results show our proposed approach exhibits the maximum data accuracy and efficient data extraction in term of the entire networks energy consumption.
