Research Areas
- Local View in Networks: Information Theory for Distributed Networks
Mismatched and incomplete network state information, aka local view, is a reality in all wireless networks. Yet, there have been no effort to develop information theoretic capacity of networks with a local view. Started in 2009, see some of the key publications.
- On Capacity Regions of Interference Channels with Mismatched Local Views, submitted to IEEE Transactions on Information Theory, Oct 2011.
- Wireless Network Coding with Local Network Views: Coded Layer Scheduling, submitted to IEEE Transactions on Information Theory, June, 2011.
- Effective Relaying in Interference Channels with Channel Output Feedback, submitted to IEEE Transactions on Information Theory, 2011.
- Paranoid Secondary: Practical cognitive interference channel , to appear in IEEE TWC, 2012.
- Optimal resource allocation with distributed decisions: subgraph scheduling (ISIT'10,IEEE-IT'11)
- Sum-capacity of Interference Channels with a Local View: Impact of Distributed Decisions, accepted for publication IEEE IT, June 2011.
- Sum-capacity of Interference Channels with a Local View: Impact of Distributed Decisions, to appear in IEEE IT, 2011.
- Full-duplex Wireless Communications: Prototypes, Protocols and Theory
In 2010, we re-purposed off-the-shelf MIMO radios used in WARP platform to develop a single-channel full-duplex wireless communication system. Combining a mix of experiment-driven data modeling and information-theoretic analysis, we have shown that full-duplex is a definite reality for short to medium range communications. See
- Distributed Cooperative Communications: Framework and Real-time Implementations
We are developing a systematic framework to construct implementable distributed cooperative communication protocols, which balance network knowledge, spatial reuse and overall network capacity.
- Directional Communication on Mobile Devices: Feasibility and Data-driven Analysis
Much like full-duplex was considered largely impossible, directional communication on mobile devices has also been considered impossible before due to their small form-factor to fit traditional directional transmissions.
- Scalable Health
Scalable health is a partnership between Rice, Texas Medical Center and University of Houston. See my recent talk on this new initiative.
News
- A team of our undergrads win the best demo prize in mHealthSys 2011. Their paper was a finalist for the best paper award.
- Rice team finishes third in the worldwide Microsoft competition, using our open-source mobile spirometer.
- I will be spending summer at NTU, Taiwan, as a visiting facutly position at Intel-NTU center.
- Patrick Murphy defended his PhD in Fall 2010. Patrick designed major pieces of WARP as part of his MS. For his PhD, he designed, implemented and experimentally studied the first real-time non-orthogonal amplify-and-forward and decode-and-forward cooperative system. See his PhD dissertation at the WARP website. Patrick plans to continue growing his startup, Mango Communications, which is a WARP spinoff.
