Abstract

Since battery still represent a constraint resource for mobile devices, mobile learning users are often forced to interrupt their learning activity because of low power situations. This paper analyses for the first time the need for a power saving solution in adaptive m-learning systems. Testing results show that battery life can be extended by varying some of the parameters of a video clip such as encoding scheme, resolution, frame rate and bitrate. Preliminary subjective tests assess the effect of these variations on learner’s Quality of Experience.
