Due to the Maxwellian nature of the wireless medium, information can be
transferred using methods quite different methods from wireline networking.
example, multiple transmissions can be simultaneously decoded at a receiver,
and concurrent transmissions in the vicinity of a receiver need not
destructively "collide." As another example, one can even use analog
than digital methods for relaying. Given the infinitude of such options, a
fundamental question that aries is: How should be information be transferred
wireless networks? This talk will address the issue of characterizing an
order-optimal architecture. Interest subsequently devolves to the issue of
to boost performance pre-constants, and what may be appropriate protocols for
such second generation protocols efforts.

His current research interests include the areas of wireless networks, sensor
networks, and the convergence of control with communication and computing.
Within this he is working on problems in network information theory,
architecture, middleware, protocol development, performance evaluation,
software development, implementation, experimentation, and application
development. More broadly he is interested in wafer fabrication plants,
manufacturing systems, machine learning, control, and stochastic systems.
