This article reviews progress in cooperative communication networks. Our survey is by no
means exhaustive. Instead, we assemble a representative sample of recent results to serve …

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 …

A Gaussian orthogonal relay model is investigated, where the source transmits to the relay
and destination in channel 1, and the relay transmits to the destination in channel 2, with …

The capacity regions are investigated for two relay broadcast channels (RBCs), where relay
links are incorporated into two-user broadcast channels to support user cooperation. In the …

Resource allocation is investigated for fading relay channels under separate power
constraints at the source and relay nodes. As a basic information-theoretic model for fading …

Relaying is a fundamental building block of wireless networks. Sophisticated relaying
strategies at the physical layer have been developed for a single flow, but multiple flows are …

A three-tier hierarchical wireless sensor network is considered that consists of a cluster of
sensors, an intermediate relay with better computing and communication capabilities than …

This paper considers a multiuser single-relay wireless network, where the relay gets paid for
hel** users forward signals, and the users pay to receive the relay service. We study the …

Networks with multiple source–destination pairs, involving possibly multicast, and where
there are multiple nodes that can serve as potential relay nodes, are considered. A …

An offset encoding technique is presented that improves sliding-window decoding with
decode-and-forward for K-user multiple-access relay channels. The technique offsets user …
