A trace-based approach for determining the energy consumption of a WLAN network interface
Jean-Pierre Ebert, Brian Burns, Adam Wolisz · 2002
The power consumption of a wireless NIC is a crucial issue because wireless nodes are often constrained by the battery due to strict requirements regarding weight and size. In the paper, we present power consumption measurement results of an Aironet PC4800 PCMCIA wireless interface which is based on Intersil's PRISM I 802.11 11 MBit/s chipset. Thereby, we vary the transmission rate, the RF transmission power, and the packet size and derive the energy consumption as a further measure. The results can be used to parameterize and to validate simulation models of an IEEE 802.11 network interfaces, and to conduct further research in the field of power saving of WLANs.
