Many studies on the energy consumpt

Many studies on the energy consumption of mobile devices and
how to optimize it have been already conducted, especially in the
context of Wi-Fi and 3G communication. For example, Chandra
et al. were among the first to study mobile device energy savings
using server side traffic shaping[4] and Balasubramanian et
al. measured the energy of 3G communication[2]. Hoque et al. investigated
different video stream delivery mechanisms from the energy
consumption perspective [8], surveyed energy efficient mobile
streaming[7], and studied the impact of streaming traffic bundling
on the energy consumption [6, 10]. A few papers have studied LTE:
Huang et. al[9] and Dusza et. al[5] both measured the energy ef-
ficiency of LTE communication. A commonality between all these
papers is their focus on downstream communications, whereas our
focus is on upstream video transmission over LTE.
