Communication device for predicting power consumption of mobile application, communication system including same, method of predicting power consumption of mobile application and method of providing predicted power consumption of mobile application, using same

A communication system, which comprises a server device, the server device comprising:

• a mobile device of a user, performing a mobile application and comprising
• a sensor trace collector, collecting sensor usage trace of the user, and
• a device trace collector, collecting device usage trace indicating usage pattern of the mobile device of the user;
• a user trace manager, managing the sensor usage trace and the device usage trace;
• a power emulator, executing an executable file and generating hardware usage statistics based on the sensor usage trace and the device usage trace;
• and
• a power impact estimator, computing an increase in power consumption based on the hardware usage statistics.

A method of predicting power consumption of a mobile application, comprising:

• a step of collecting a user's sensor usage trace and device usage trace showing the user's usage pattern of the user's mobile device;
• a step of executing an executable file of the mobile application and generating hardware usage statistics based on the sensor usage trace and the device usage trace;
• and
• a step of computing an increase in power consumption of the mobile application based on the hardware usage statistics.

A method of providing estimated power use of a mobile application, comprising:

• collecting a user's sensor usage trace and device usage trace reflecting the user's mobile device usage pattern;
• generating hardware usage statistics based on the sensor usage trace and the device usage trace by executing an executable file of the mobile application;
• computing an increase in power use of the mobile application based on the hardware usage statistics;
• determining a decrease in operation time of the mobile device based on the increase in power use, when the mobile application is executed;
• and
• displaying the decrease in operation time in a display unit of the mobile device.
