Query: Evolution of IEEE 802.11 compatible standards and impact on Energy
  Consumption   Over the last decade, the IEEE 802.11 has emerged as the most popular
protocol in the wireless domain. Since the release of the first standard
version, several amendments have been introduced in an effort to improve its
throughput performance, with the most recent one being the IEEE 802.11n
extension. In this work, we present detailed experimentally obtained
measurements that evaluate the energy efficiency of the base standard in
comparison with the latest 802.11n version. Moreover, we investigate the impact
of various MAC layer enhancements, both vendor specific and standard compliant
ones, on the energy consumption of wireless transceivers and total nodes as
well. Results obtained under a wide range of settings, indicate that the latest
standard enables reduction of energy expenditure, by more than 75%, when
combined with innovative frame aggregation mechanisms.
