Title
An energy efficient user context collection method for smartphones
Abstract
Recently, user context information has been utilized for efficient and effective network and service management. In this situation, there is a strong need to collect user context information. One of the proprietary methods to collect user context information is to use sensors equipped inside a smartphone such as accelerometer, gyroscope, digital compass, and microphone. However, user context collection on a smartphone easily leads to rapid drain of the smartphone battery. To overcome the problem, this paper proposes a novel user context information collection model for efficient smartphone battery management. This model is based on two strategies: scheduling and dynamic sensor reconfiguration. The proposed model is implemented on Galaxy Nexus Android smartphone. The Performance evaluation shows that the proposed model reduces the energy consumption by a ratio of 42 percent compared to the current periodic sensor reading model.
