We develop analytical models for estimating the energy spent by stations(STAs) in infrastructure WLANs when performing TCP controlled file downloads.We focus on the energy spent in radio communication when the STAs are in theContinuously Active Mode (CAM), or in the static Power Save Mode (PSM). Ourapproach is to develop accurate models for obtaining the fraction of times theSTA radios spend in idling, receiving and transmitting. We discuss two trafficmodels for each mode of operation: (i) each STA performs one large filedownload, and (ii) the STAs perform short file transfers. We evaluate the rateof STA energy expenditure with long file downloads, and show that static PSM isworse than just using CAM. For short file downloads we compute the number offile downloads that can be completed with given battery capacity, and show thatPSM performs better than CAM for this case. We provide a validation of ouranalytical models using the NS-2 simulator. In contrast to earlier work onanalytical modeling of PSM, our models that capture the details of theinteractions between the 802.11 MAC in PSM and certain aspects of TCP.
