SLA-Aware Adaptive On-demand Data Broadcasting in Wireless Environments

Adrian Daniel Popescu

In mobile and wireless networks, data broadcasting for popular data items enables the efficient utilization of the limited wireless bandwidth. However, efficient data scheduling schemes are needed to fully exploit the benefits of data broadcasting. This mo ...

Information-theoretic secrecy for wireless networks

Etienne Perron

The aim of information-theoretic secrecy is to ensure that an eavesdropper who listens to the wireless transmission of a message can only collect an arbitrarily small number of information bits about this message. In contrast to cryptography, there are no ...

Achievable Flows on Orthogonal Information Networks

Dinkar Vasudevan

We examine routing over two classes of orthogonal information networks. The first is a relay network with orthogonal inputs. The nodes in this network do not broadcast, but communicate to the different nodes via independent inputs. There is multiple access ...

The scaling of the broadcast capacity of extended wireless networks with cooperative relays

Michael Christoph Gastpar

We study the scaling of the broadcast capacity for a network with a single source and f(N) cooperative relays where N is the number of destinations and f(.) is an increasing function. We consider random extended networks (the network area goes to infinity ...

Broadcast, relay and feedback in Gaussian channels

Sibi Raj Bhaskaran Pillai

Network information theory explores the fundamental data transport limits over communication networks. Broadcasting and relaying are two natural models arising in communication contexts where multiple users share a common communication medium. Number of re ...

Cooperative strategies and capacity theorems for relay networks

Michael Christoph Gastpar

Coding strategies that exploit node cooperation are developed for relay networks. Two basic schemes are studied: the relays decode-and-forward the source message to the destination, or they compress-and-forward their channel outputs to the destination. The ...

Information-theoretic multi-hopping for relay networks

Michael Christoph Gastpar

Recent advances in multi-hopping are extended to relay networks having multiple antennas and multiple sources. As for the single-antenna and single-source case, one can achieve the ergodic capacity of wireless relay networks with phase fading if the relays ...
