One of the basic conditions that must have a modern mobile phone is to have WiFi connectivity. This technical feature can access a web connection, with the benefit that means saving our spending (if limited) for Internet downloads. Music, movies, series, videos from YouTube, Tweets, updating our profile on Facebook and thousands of applications that we serve. However, all good things it can offer, does not leave out a serious problem: the length of our battery is reduced significantly. SleepWell is a piece of software that will increase the battery life on your phone twice (yes, you read right) without leave to enjoy your favorite applications. If you use WiFi on your phone, this article is what you were expecting.
Although the technicians and engineers set about the task of developing new technologies, make their best efforts on energy management to a near-optimal limit on mobile devices, WiFi connectivity remains a major energy guzzlers. Mobile devices are designed to efficiently act as an access point "only" within a network. However, when the access points increases (other devices requesting data), the system is responsible for organizing and directing data to the different teams can make some spend long periods of time "awake" waiting for their chance to send orreceive data packets. As the density of AP (Access Point) in the neighborhood increases, increases the waiting time, resulting in a proportional decrease in battery life. SleepWell is a system that achieves energy efficiency and avoid permanent dependence on the network. The operating principle of the system is simple to understand and is based on off ("put to sleep") during specific time windows to the devices. That is, organize the network so that all WiFi devices to connect to it are not on a permanent waiting "their turn", but are activated during small time intervals and exchange data when necessary.
