There are three reasons why bundling
saves energy: 1) smaller signaling overhead 2) less overhead due
to packet headers, 3) less tail energy. 1 is acheived because frames
are sent in continuous batch. Less frequent transmission makes 3
acheivable. On analyzing real-time video transmission in LTE we
found out that 2 can be acheived only if frame size is smaller than
TCP’s maximum segment size (MSS). Hence, lesser the bitrate,
higher are the savings through 2. We now briefly study the impact
of bundling in analytical manner
