Abstract

This paper presents a method for dynamically setting 802.11 wireless LAN waveforms and transmission power levels based on the wireless channel's signal to noise ratio. Our method, known as Signal-to-Noise Ratio-Waveform Power Adaptation (SNR-WPA), changes the power in discrete steps matched to each of the 802.11 data rate-waveform steps. By matching the power to the spreading symbol rate, our technique maximizes the network throughput while minimizing MAC layer contention. Unlike other power adaptation methods, this method does not increase the Wireless LAN (WLAN) station's overall effective operational range and does not change the minimum-spanning tree used to calculate routing. We found through experimentation that the power adaptation in SNR-WPA yields up to a 30% increase in throughput in a mobile wireless LAN network.

Conference

Conference	IEEE International Conference on Communications 2004
Abbreviated title	ICC 2004
Country	France
City	Paris
Period	20/06/04 → 24/06/04
Other	The 2004 International Conference on Communications (ICC 2004) will be held in Paris, France, on 20-24 June 2004. The technical program will feature a unique set of technical symposia disseminating the latest research and development results in communications and networking, and business applications sessions and panels, where industry leaders will address the hottest topics in telecommunications and the future evolutions of this field. In addition, the program will include tutorials and workshops by internationally recognized experts, where engineers can learn about new technologies of their choice. ICC 2004 will thus feature a technical program equally attracting researchers from academia and engineers from industry, network operators, and service providers.
