We only measured audio streaming over LTE but the results
give indications of what the results would be for video
streaming cases as well. The results in Figure 7 show that
traffic shaping can save some energy even when cDRX is
disabled. However, when shaping the traffic through the
proxy, we can save almost up to 60% of energy in the best
case when cDRX is enabled. Moreover, we note that enabling
cDRX does not help at all when streaming directly
from the server.
