Abstract:
The issue of power consumption in wireless networks is becoming increasingly important due to the rapid development of various wireless devices such as sensors, smartphones, and tablet PCs. The IEEE 802.11 wireless LAN standard defines multiple data transmission protocols, each of which has various characteristics such as power consumption, data rate, modulation method, and transmission distance. Therefore, it is important to choose the optimal data rate in terms of power consumption as well as throughput, especially when considering data transmission over multi-hop networks. In this paper, we present a mathematical analysis of power consumption in data transmission over IEEE 802.11-based wireless multi-hop networks to investigate the effect of data rate selection on power consumption. The analysis results show that there are some situations where a low data rate should intentionally be selected in order to minimize power consumption. Our analysis indicates that power consumption can be decreased by up to 13% when the symbol error rate is comparatively small.
