TLDR
This article reviews progress in cooperative communication networks and intends its presentation to be a tutorial for the reader who is familiar with information theory concepts but has not actively followed the field.Abstract:
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 as a roadmap for the area. Our emphasis is on wireless networks, but many of the results apply to cooperation in wireline networks and mixed wireless/wireline networks. We intend our presentation to be a tutorial for the reader who is familiar with information theory concepts but has not actively followed the field. For the active researcher, this contribution should serve as a useful digest of significant results. This article is meant to encourage readers to find new ways to apply the ideas of network cooperation and should make the area sufficiently accessible to network designers to contribute to the advancement of networking practice.read more

Analytical Modeling of Medium-Access Delay for Cooperative Wireless Networks Over Rayleigh Fading Channels
TL;DR: An analytical model is developed centered around a 2-D Markov chain, similar to that introduced by Bianchi for IEEE 802.11, that empowers it to derive the probability density function of medium-access delay in CoopMAC from which any higher statistical moments can be obtained.
Network Simplification: the Gaussian N-Relay Diamond Network
TL;DR: It is shown that in every Gaussian-relay diamond network, there exists a subset of relays which alone provide approximately a fraction of the total capacity, which is within $3\log N+3k$ bits/s/Hz to the capacity.

A converse for the wideband relay channel with physically degraded broadcast
Nadia Fawaz,Muriel Medard +1 more
TL;DR: A hypergraph model of the multipath fading relay channel is proposed, and the relaying scheme of concern is shown to reach its min-cut, which coincides with the block-Markov lower bound on the capacity of the wideband frequency-division Gaussian relay channel.

Optimizing cooperative video streaming in wireless networks
TL;DR: An asynchronous, distributed and localized low-complexity algorithm is designed, based on the iterative solution of convex optimization problems at each individual node, and a global-optimization centralized algorithm based on convex relaxations of non-convex constraints is proposed as performance benchmark.

Search space for epdcch control information in an ofdm-based mobile communication system
TL;DR: In this paper, the authors proposed a method for receiving control information within a subframe of a multi-carrier communication system supporting carrier aggregation, the method comprising the following steps performed at a receiving node: performing a blind detection for the control information by means of a first search pattern, wherein the first search patterns is one of a plurality of search patterns.

Cooperative diversity in wireless networks: Efficient protocols and outage behavior
TL;DR: Using distributed antennas, this work develops and analyzes low-complexity cooperative diversity protocols that combat fading induced by multipath propagation in wireless networks and develops performance characterizations in terms of outage events and associated outage probabilities, which measure robustness of the transmissions to fading.
