In this paper, the authors provide an in-depth understanding of the per-frame energy consumption behavior in 802.11 Wireless LAN (WLAN) devices. Extensive measurements are performed for 7 devices of different types (wireless routers, Smartphone's, tablets and embedded devices), and for both UDP and TCP traffic. Experimental results unveil that a substantial fraction of energy consumption, hereafter descriptively named cross-factor, may be ascribed to each individual frame while it crosses the protocol stack (OS, driver and NIC) and is independent of the frame size.
