Dynamic Transmission Power Control Mechanism for Maximizing Energy Efficiency of WLAN
Gan Ding, Dong Liang, Wen Bo Wang, Shu Long Liu · Advanced materials research · 2013
Energy efficiency is not fully considered as the key factor compared with coverage and interference in the conventional wireless local area network (WLAN) deployment phase in the past. However, energy consumption is increasing exponentially with the heavy growing number of mobile nodes (MN). As a result, excessive use of energy is becoming a serious problem even a disaster in multi-base-station WLAN. In this paper, a mechanism of transmission power configuration in WLAN deployment and dynamic transmission power control during WLAN running phase is proposed focusing on the energy efficiency and coverage. The performance of the mechanism has been experimentally evaluated at the system level and system-wide power usage on the demonstration testbed.
