Abstract

As mobile devices are constantly improving, they have started to be used for online learning. If the delivery of educational content involves multimedia streaming, additional pressure is put on the battery life, causing it to discharge faster. Running out of battery life during a learning session can have a negative impact on the learner’s Quality of Experience. This paper suggests the fact that adaptive e-learning environments should become energy-aware and power saving techniques should be considered in order to assist the learner in a low power situation. The impact of various factors on the battery life was analysed and the results show that significant power saving can be achieved by applying different techniques during the multimedia streaming process. However, subjective tests conducted on a small group of participants show that some of these techniques have a negative impact on end-user perceived quality and may not be suitable for an e-learning environment.
