Abstract
In this paper is presented an improved channel
reservation algorithm for transmission power controlled
IEEE 802.11b WLAN. The power control algorithm adjusts
transmission power of mobile stations, which operate in
an infrastructure DCF mode. The purpose of the power
control algorithm is to maintain received signal power of
power controlled frames on a nominal power level under
the influence of channel fluctuations.
The introduced algorithm is based on absolute power level
coding of power control commands and the length of the
command word was minimized to four bits per power
controlled frame.The advantage of the developed power
control algorithm is considerable energy saving and the
disadvantage is decreased network throughput.
Channel reservation was modified for better overall
performance with the power control. The better
performance was realized especially in the channel
occupancy fairness between the contending stations.
