Programming Strategy to Reduce Energy Consumption of Smartphone Sensors

This paper presents a strategy to reduce the energy demand of network applications running on a smartphone, by specifying regular intervals for the recurrent services required by these applications. Although there are several initiatives for reducing energy consumption on smartphones, there is a bad practice of software developers for mobiles in which the energy consumption of sensors is not considered as a requirement. Therefore, this work proposes a software pattern for developing mobile applications that allows managing sensors’ energy consumption. It contributes for the improvement of energy efficiency. In order to test the efficiency of the proposed solution, two tests were conducted: (1) normal consumption, the application was executed without implementing any method to reduce its energy consumption, and (2) low consumption, where the application was executed by applying the schemas used to reduced the demand for energy on the GPS and Wifi sensors. The energy consumption associated with such strategy demanded less than 20% of the energy required by ordinary mobile applications.
