Analysis of Types and Importance of Sensors in Smart Home Services

Abstract
In the paradigm shift of smart home to smart city, more sensors and smart objects will be deployed for user-centric service. To design the advanced smart city, understanding and analysis of duplicated sensors in current smart home services is important. In this paper, we categorize the smart home services and analyze the types of sensors that used in the smart home, and then we estimate the importance of sensors using the sensor tree. As a result, the motion sensor has high importance score and it is used in 7 smart home services.
