A study on application-aware power-saving control method for sensor stations in home gateway

In recent years, home ICT services have been actively proposed. To realize the services, power consumption of sensor station increases when a sensor station often wakes up to report sensor data. In this paper, we proposed an application-aware power-saving control method for sensor stations and confirmed an effect of a proposed method which is constructed as OSGi bundle in HGW. By using the proposed method, it is possible to extend a reporting period of sensor station to a requesting period of service providing server. And a timing difference between reception of sensor data and reception of request from the server in HGW can be reduced to 49 msec in the evaluation.
