Recently, smart home construction based on Internet-of-Thing (IoT) has been actively performed, and smart devices including various sensors have been used for building a smart home. Many sensors in a smart home collect specific data, collect them in a central server and provide smart home residents or organically manage smart homes by combining them with artificial intelligence. However, each sensor transmits data to a central server, resulting in power consumption, which leads to a reduction in energy efficiency.In this paper, we propose an Adaptive Sensor Data Transmission Scheduling Scheme that schedules data transmission interval based on the data variation of each sensor. The proposed scheme reduces the total amount of data transmission by classifying the class adaptively according to the amount of data measured in the sensor of the device and excluding unnecessary data transmission. As a result, the proposed scheme reduces power for exchanging data between various devices and the central server.
