—In this paper, a channel-driven rate and power adaptation (CDRPA) algorithm is proposed for wireless local area networks (WLANs) in generalized Nakagami fading channels. Through the channel information of the first packet, the CDRPA algorithm can lower the complexity of comparing various rates and power levels. In the case of the IEEE 802.11 WLAN, the(More)
— In this paper, we propose a fast joint rate and power adaptation algorithm for wireless local area networks (WLAN). The proposed algorithm adjusts the rate and power for frame transmission according to the channel state observed at the physical layer, and is named as channel-driven rate and power adaptation (CDRPA) algorithm. The CDRPA algorithm first(More)
Adaptively adjusting transmission rate and power to concurrently enhance goodput and save energy is an important issue in the wireless local area network (WLAN). However, goodput enhancement and energy saving are two contradictory goals, since high data rate usually requires high transmission power to meet the bit-error-rate (BER) requirement. To achieve(More)
