Absence of perfect network state information and presence of output feedback links in wireless networks have both attracted significant amount of interest in recent years.

© 1972-2012 IEEE. The multi-version coding problem is a recently formulated information-theoretic framework to study the storage cost of consistent key-value data stores.

We consider a single cell wireless uplink in which randomly arriving devices transmit their payload to a receiver. We study the following problem.

Since the beginning of the integrated-circuit era in 1958, the minimum device dimension for commercial integrated circuits has been reduced at an annual rate of about 13%.

We address the problem of evaluating the ultimate performance of zero-forcing nonlinear equalizers in coherent WDM fiber-optic systems, which is due to nonlinear interactions between signal and ASE

Fundamental energy limits in communication systems are reviewed and applied to a gedanken network model in order to determine the corresponding ideal minimum energy requirements on classical, non-a

We show that the quantum limit for the energy efficiency of a multi-span communication system deploying generalized on-off keying with photon-counting inline regeneration exceeds that of an ampli

We study congestion control for one-to-many multicast applications in the Internet and establish a three-way relationship between the choice of regulation parameter (i.e., rate or window size), the

Photoluminescence spectra of pentacene clusters and films of few monolayers in thickness reveal two fundamental excitations that are assigned to the Davydov doublets of the lowest singlet exciton.

This paper covers the general switching plan and fundamental plant layout proposed for handling telephone toll messages throughout the United States and Canada using automatic toll switching.
