Sps: An Sms-Based Push Service For Energy Saving In Smartphone'S Idle State

Abstract

Despite of all the advances in smartphone technology in recent years, smartphones still remain limited by their battery life. Unlike other power hungry components in a smartphone, the cellular data and Wi-Fi interfaces often continue to be used even when the phone is in its idle state in order to accommodate background (necessary or unnecessary) data traffic produced by some applications. In addition, bad reception has been proven to greatly increase energy consumed by the radio, which happens frequently when smartphone users are inside buildings. In this paper, we present a Short message service Push based Service (SPS) system to save unnecessary power consumption when smartphones are in idle state, especially in bad reception areas. First, SPS disables a smartphone's data interfaces whenever the phone is in idle state. Second, to preserve the real-time notification functionality required by some apps, such as new email arrivals and social media updates, when a notification is needed, a push server will deliver a wakeup text message to the phone (which does not rely on data interfaces), and then SPS enables the phone's data interfaces to connect to the corresponding server to retrieve notification data via the normal data network. Once the notification data has been retrieved, SPS will disable the data interfaces again if the phone is still in idle state. We have developed a complete SPS prototype for Android smartphones. Our experiments show that SPS consumes less energy than the current approaches. In areas with bad reception, the SPS prototype can double the battery life of a smartphone.
