The PinDrop project focuses on building the substrate for supporting high-quality real-time streaming over wired and wireless networks. Context Real-time streaming across the wide-area network (WAN) is key to several existing and anticipated services, including voice and video conferencing (e.g., Skype, Viber), remote console access (e.g., remote desktop, VNC), remote application streaming (e.g., Azure RemoteApp), and cloud-based gaming. A common characteristic of these services is bidirectional interactive communication, between two or more users or between a user…

Phytics: Physical Analytics

Established: February 18, 2013

The goal of the Physical Analytics project, or Phytics, is to perform analytics on the physical actions of users. Such analytics would be valuable in a variety of contexts where the design of a physical space is intertwined with how users use the space, e.g., to understand the behaviour of shoppers in mall or a store, which might be indicative of their interests; to fine-tune the layout of services in an airport or a train…

Many networked applications that run in the background on a mobile device incur significant energy drains when using the cellular radio interface for communication. This is mainly due to the radio-tail, where the cellular radio remaining in a high energy state for up to 20s after each communication spurt. In order to cut down energy consumption, many recent devices employ fast dormancy, a feature that forces the client radio to quickly go into a low…

Recognizing the twin trends of a rapid growth of cellular data services and the commoditization of WiFi WLAN technology, Cool-Tether proposes an architecture for ubiquitous and affordable connectivity by harnessing mobile smartphones to create WiFi hotspots on the fly. Cool-Tether optimizes heavily for battery energy consumption on the smartphones, resulting in a 38%-72% savings in energy consumption compared to prior energy-agnostic solutions for tethering.
