Abstract
Understanding the energy consumption of wireless
interfaces is critical to provide guidelines for the design and
implementation of new protocols or interfaces. In this work we
analyze the energy performance of an IEEE 802.11 WLAN.
Our contributions are as follows: i) we present an accurate
analytical model that is able to predict the energy consumption,
ii) we present an approximate model that sacrifices accuracy for
the sake of analytical tractability, iii) based on this simplified
analysis, we derive the optimal configuration to maximize energy
efficiency of a WLAN, and iv) finally, we also analyze the tradeoff
between throughput and energy efficiency that IEEE 802.11
imposes. While most of these results consider a homogeneous
WLAN scenario where all stations share the same energy
features, we also discuss the case of heterogeneous environments,
where different devices show different power consumption characteristics.
