Student Forum @ WINLAB (formerly known as 'WINLAB Student Seminar') is a peer-to-peer learning forum for students to discuss research work with their fellow students who share common interests, get suggestions, prepare for a conference talk or give tutorials on some special skill set in a little informal setting. We are also looking forward to connect to PhD students from other universities working in the areas of wireless communications, networking, etc. Last but not least, we do want to interact with our WINLAB alumni to know how they are doing in their professional life.

9/22/2014 Shreyasee Mukherjee Network-Assisted Multihoming for Emerging Heterogeneous Wireless Access Scenarios

[Abstract] [Slides] [Paper]

This work presents a technique for enabling multihoming in the emerging heterogeneous (“hetnet”) mobile wireless access scenarios, where mobile devices have dual wireless interfaces (such as Wi-Fi and LTE) and can use either or both to achieve significant improvements in performance and service quality. A novel network-assisted technique for multihoming is introduced, enabled by the globally unique identifier (GUID) based routing in the proposed MobilityFirst Future Internet architecture, now under development. In particular, the approach shifts the burden of policy expression and data-striping from end-nodes to in-network nodes, and utilizes named object routing with GUIDs to establish multiple paths to destination mobile devices. The proposed multihoming technique uses hop-by hop backpressure for data striping at the bifurcation router and includes a robust mechanism to reduce reordering of packets at the receive buffer. We quantify the performance gains using detailed NS3 based simulations and present results from a thorough parametric study to determine the effects of datarate, delay and hop-count difference between multiple available paths. We also show that when multiple interfaces are available, simultaneous use of both the interfaces is beneficial only under certain conditions depending on the ratio of the data-rate of the interfaces and the size of the flow.

9/3/2014 Viet Nguyen Do Not Share! Invisible Light Beacons for Signalling Preferences to Privacy-Respecting Cameras

[Abstract] [Slides] [Paper]

The ubiquity of cameras in today’s world has played a key role in the growth of sensing technology and mobile computing. However, on the other hand, it has also raised serious concerns about privacy of people who are photographed, intentionally or unintentionally. We are exploring the use of near-visible/infrared light communication to design “invisible light beacons" where privacy preferences of photographed users are communicated to cameras. Particularly, we explore a design where the beacon transmitters are worn by users on their eye-wear and transmit a privacy code through ON-OFF patterns of light beams from IR LEDs.
