Cell phone running out too fast? The problem may depend on the various protocols we use to surf the net, and the latest ones may not necessarily also be the most energy efficient. The news comes from a study by the University of Pisa and the CNR Institute of Informatics and Telematics recently published in the journal Pervasive and Mobile Computing. "Generally, when talking about the different versions of the HTTP protocol, the focus is on 'performance' understood as the time it takes to download data and resources through the network," explains Alessio Vecchio author of the study and professor at the Department of Information Engineering of the University of Pisa. "Our study instead focused on energy consumption, which is particularly relevant in the context of the Internet of Things (IoT), where many devices are battery-powered. In this context, saving energy can significantly extend the life time of the device, avoiding the replacement or recharging of batteries with positive consequences in terms of sustainability and usability”.
