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

摘要

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.
