att_abstract={{Mobile application developers pay little attention to the interactions between applications and the cellular net- work carrying their traffic. This results in wastage of de- vice energy and network signaling resources. We place part of the blame on mobile OSes: they do not expose adequate interfaces through which applications can in- teract with the network. We propose traffic backfilling, a technique in which delay-tolerant traffic is opportunis- tically transmitted by the OS using resources left over by the naturally occurring bursts caused by interactive traffic. Backfilling presents a simple interface with two classes of traffic, and grants the OS and network large flexibility to maximize the use of network resources and reduce device energy consumption. Using device traces and network data from a major US carrier, we demon- strate a large opportunity for traffic backfilling.}},
