Abstract

In this paper, I proposed a method to optimize the query using MJoin operator which is hash table-window based join operator in order to process stream data with fast and continuous characteristics collected in the sensor network of Internet of Things and efficiently manage stream data. And I classified and reduced the data using the SVM algorithm. In order to recognize the situation of home system based on Internet of Things, I classified the sensor data (temperature, humidity, gas) and date data into the decision tree and used the sensor data to set the device. It is expected that the efficiency and convenience of the system will be increased because it is more intelligent than the existing home system and the environment can be set according to the characteristics of the users.
