Ergodic stochastic optimization algorithms for wireless communication and networking
— Ergodic stochastic optimization (ESO) algorithms are proposed to solve resource allocation problems that involve a random state and where optimality criteria are expressed in t...

VBR over VBR: The Homogeneous, Loss-Free Case
We consider the multiplexing of several variable bit rate (VBR) connections over one variable bit rate connection where the multiplexing uses a multiplexing bu er of size B. The V...

Optimal Wavelength Sharing Policies in OBS Networks Subject to QoS Constraints
— We consider the general problem of optimizing the performance of OBS networks with multiple traffic classes subject to strict (absolute) QoS constraints in terms of the end-to...

Computing the Optimal Amount of Constellation Distortion in OFDM Systems
Abstract— The primary disadvantage of orthogonal frequencydivision multiplexing (OFDM) is the high time-domain peak-toaverage power ratio (PAR) that severely limits the transmitt...

Throughput-Optimal Scheduling in Multichannel Access Point Networks Under Infrequent Channel Measurements
—We consider the problem of uplink/downlink scheduling in a multichannel wireless access point network where channel states differ across channels as well as users, vary with tim...
