MobiCom 2010 Poster : BeamAdapt : Energy Efficient Beamsteering on Mobile Devices
نویسندگان
چکیده
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.

Beamsteering on Mobile Devices: Network Capacity and Client Efficiency
Current and emerging mobile devices are omni directional in wireless communication. Such omni directionality not only limits device energy efficiency but also poses a significant challenge toward the capacity of wireless networks through inter-link interference. In this work, we seek to make mobile clients directional with beamsteering. We first demonstrate that beamsteering is already feasible...

In this poster we describe initial findings regarding Internet usage characteristics, in particular TCP flows from a field study with 27 iPhone 3GS users. We present details regarding their usage characteristics, and provide a solution for migrating flows between different networks and/or network interfaces without requiring infrastructure support or changes to current applications and protocol...
متن کاملMobiCom Poster: Evaluating location predictors with extensive Wi-Fi mobility data
A fundamental problem in mobile computing and wireless networks is the ability to track and predict the location of mobile devices. An accurate location predictor can significantly improve the performance or reliability of wireless network protocols, the wireless network infrastructure itself, and many applications in pervasive computing. These improvements lead to a better user experience, to ...
متن کاملMobiCom 2010 Poster: Traffic Shaping in Wireless Home Networks
Many devices commonly found in wireless home networks such as smartphones, gaming consoles and media servers generate real-time traffic with stringent performance requirements. Since the wireless medium is mostly accessed in a distributed manner (DCF), sensitive traffic needs to be ”protected”. This work investigates how mechanisms defined in the WiFi standard such as virtual carrier sensing an...
