Dynamic Adaptive Streaming over HTTP (DASH) is a standard for media streaming that has been largely adopted, as it allows improved quality of experience (QoE) and the streaming host only needs to adopt conventional web server infrastructure. Despite DASH's feasibility for enhancing QoE, mobile devices are constrained by battery capacity, and video streaming can be a major source of energy consumption. This work evaluates DASH for video streaming on mobile device, taking into account QoE and energy consumption, and the following factors are investigated: (i) network technology; (ii) network bandwidth; and (iii) video type (with and without DASH). Results demonstrate these factors and their interactions can have great influence on energy consumption and QoE.
