Abstract

Methods, systems, and computer program products are disclosed for controlling data transmission based on power cost. A power cost per unit data associated with successfully sending data from a wireless mobile device to a remote endpoint in a communications network is determined. The determined power cost per unit data is compared to a first threshold. Transmission of data from the wireless mobile device to the remote endpoint is delayed based on a determination that the power cost per unit data exceeds the first threshold.
