MobiCom 2010 Poster

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...

MobiCom Poster Abstract: Traffic-Aware Channel Assignment in Wireless LANs

Campus and enterprise wireless networks are increasingly characterized by ubiquitous coverage and high traffic demands. An efficient channel assignment of access points (APs) in these networks has the potential to greatly improve wireless LAN performance. Therefore, previous studies have investigated methods for determining effective channel assignments. Existing approaches, however, do not ada...

MobiCom 2010 Poster : BeamAdapt : Energy Efficient Beamsteering on Mobile Devices

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 efficienc...

MobiCom 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...
