Abstract:

Interest in in-band full-duplex, where the nodes can simultaneously send and receive in the same frequency band, has recently received significant attention due to system-level demonstrations by multiple research groups. However, enabling multiple simultaneous links leads to an increased interference in networks, which can potentially wipe out gains from in-band full-duplex. In this talk, we will present results to characterize network capacity in the presence of increased inter-node interference in networks with full-duplex nodes. The results point to a novel use of full-duplex, where the nodes can leverage the full-duplex links between the mobile nodes to manage inter-node interference.

Ashutosh Sabharwal is a Professor in the Department of Electrical and Computer Engineering at Rice University. He currently works in two research areas. First is wireless networks, spanning theoretical foundations, protocols and experimental systems. He is the founder of the WARP project (http://warp.rice.edu), which enables high-performance clean-slate prototyping of wireless networks, and is now in use in 125+ organizations worldwide. Second is scalable methods for healthcare, where the research emphasis is on smart and mobile diagnostic devices,  and methods for large-scale behavior change. This second research area has rapidly grown into a Scalable Health Initiative (http://sh.rice.edu), involving multiple faculty from Rice and many collaborators from Texas Medical Center.
