2011 Poster Sessions : Achieving Single Channel Wireless Full-Duplex

Student Name : Dinesh Bharadia, Jung Il Choi, Mayank Jain, Taemin Kim
Advisor : Philip Levis
Research Areas: Computer Systems
Abstract:
We present the design of a single channel full-duplex wireless transceiver. The design uses a combination of RF and baseband techniques to achieve full-duplexing with minimal effect on link reliability. Experiments on real nodes show the full-duplex prototype achieves median performance that is within 8% of an ideal full-duplexing system.
The potential MAC and network gains with full-duplexing go beyond doubling the physical layer throughput. A full-duplex system can solve some important problems with existing wireless systems including hidden terminals, loss of throughput due to congestion, and large end-to-end delays. We will discuss some of these gains.

Bios:
Omitting Tae Min and Dinesh, since they weren't authors on the material that will be presented in the poster. The other co-authors (non-student) on this poster would be Kannan Srinivasan and Sachin Katti. The student bios are the following:

Mayank Jain is a PhD candidate in the Electrical Engineering department at Stanford. He is currently working in the Stanford Information Networks Group under the supervision of Professor Philip Levis. Mayank completed his B.Tech in Electronics and Communications from NSIT, Delhi, India in 2002. He then worked at Texas Instruments for 3 years, designing chips for Wireless LAN systems. He came to Stanford in Fall 2005. Prior to doing wireless research, he was working in the Stanford Photonics and Networking Research Laboratory.

Jung Il Choi is a PhD candidate in the Electrical Engineering department at Stanford since 2007, advised by Professor Philip Levis. He received his B.S. in Seoul National University in 2005 in South Korea. His research interest includes full duplex radios, more efficient wireless MAC protocols, and improving robustness of wireless sensor networks.
