Title
BeamAdapt: energy efficient beamsteering on mobile devices
Abstract
All current mobile devices are omni directional in transmission, which not only limits device energy efficiency but also poses a significant challenge toward network capacity through inter-link interference. In this work, we make mobile devices directional with beamsteering. By allowing a dynamic number of antennas in beamsteering, we reveal an important tradeoff between device energy efficiency and network capacity. We then provide a distributed algorithm called BeamAdapt that allows each mobile device in the network to closely approach the optimal tradeoff, with minimum aggregated device power to achieve certain network capacity. We also offer a cellular system realization of BeamAdapt as well as a Qualnet-based evaluation. The results show the effectiveness of BeamAdapt in device power reduction without sacrificing network throughput.
