Our simulation results reveal that bundling is highly effective
way to save energy and that only one second of bundling is enough
in some cases to cut the energy consumption to half. Video bitrate
has a clear impact on the energy savings achievable so that high
bitrate videos provide a smaller opportunity for savings. We also
study the impact of network characteristics on the energy savings,
namely round-trip time (RTT), packet loss, mobility, and crosstraffic.
The results confirm that while all of these have a negative
impact on the energy savings, the impact is relatively small with
realistic scenarios.
