| Summary: | In this paper, we describe an empirical study on
the impact of throughput performance when transmission
power is adjusted. This experiment was conducted in an office
environment for an OFDM-based wireless communication
system such as WiFi 802.11g protocol network
.
We present a
power selection mechanism based on intuitively learning one of
the attributes which then triggers the power adjustment. We
show that client’
s similar throughput performance can be
obtained at reduced transmission power thus prevent an access
point from maximizing power unnecessarily. Our cognitive
power adjustment method is potentially useful in extremely
dense wireless networks deployment since it is able to prevent
from any interference and also to reduce energy consumption of
the devices. Our evaluation of this mechanism can reduce the
power to 5dB while maintaining the same level of throughput. |
