Energy efficient transmission power estimation for WLAN VoIP
In this paper transmission signal power is optimized to increase the energy efficiency of Wireless Local Area Network (WLAN) Voice over IP (VoIP) application. We investigate how to optimize the transmission power without degrading the VoIP Quality of Service (QoS). A Transmission Power Optimization (TPO) algorithm is presented to adopt lowest possible transmission power that does not interrupt the VoIP service quality and increases energy efficiency as well. Extensive analysis is done in Network Simulator-2 (NS-2) [1] to estimate the optimal transmission power for various channel condition. According to our simulation results and analysis it is observed that the optimal transmission power increases the energy efficiency and improves the VoIP performance significantly.
