Cím:	Szenzor adatklaszterek wavelet elemzése = Wavelet analysis of the sensor data clusters / Gál Zoltán
Dátum:	2014
Megjegyzések:	One of the hot topics of the Future Internet technologies is the Internet of Things (IoT). Services marked with "smart" attribute like smart cities, smart energy usage, smart health, smart industry, smart transportation have huge effects on the economy, society and technology. Variables sampled with sensors increases significantly the volume of processed data. The Big Data symptom makes necessary to re-evaluate the maximum number of variables sampled for optimal controlling of different processes. The increase of the number of Internet nodes by one order of magnitude until the end of current decade induces serious effort to develop low consumption, secure wireless communication technologies. Need to determine the sampling type and sampling frequency to relieve the usage of finite energy source of the sensors battery. This is one of the most important challenges required to be answered for cost efficiency of the intelligent processes control. In this paper we analyse different information extraction methods from data sampled from high number of sensors. We use data cluster analysis to group variables and determine the representing entity with DBSCAN (Density-Based Spatial Clustering of Applications with Noise) algorithm. Variables determined are analysed with wavelet transformation to detect in time the surprise event formation of the controlled process. Analysis results and comparison of data sets sampled from different systems as sources (i.e. supercomputer, wide-area network) are presented.
