The evolution of cooperation in network-structured populations has been a major focus of theoretical work in recent years. When players are embedded in fixed networks, cooperators are more likely to interact with, and benefit from, other cooperators. In theory, this clustering can foster cooperation on fixed networks under certain circumstances. Laboratory experiments with humans, however, have...

In this paper, we propose a new cooperation model for discrete memoryless multiple access channels (DM-MACs). While in prior cooperation models (e.g., DM-MAC with conferencing encoders) the increase in a network’s sum-capacity that results from cooperation is no more than the rate introduced by the cooperation mechanism, we show that in our model for a particular sequence of channels, the incre...

In this paper we study the influence of random network fluctuations on the behavior of evolutionary games on Barabási-Albert networks. This network class has been shown to promote cooperation on social dilemmas such as the Prisoner's Dilemma and the Snowdrift games when the population network is fixed. Here we introduce exogenous random fluctuations of the network links through several noise mo...

We study the evolution of cooperation in a structured population, combining insights from evolutionary game theory and the study of interaction networks. In earlier studies it has been shown that cooperation is difficult to achieve in homogeneous networks, but that cooperation can get established relatively easily when individuals differ largely concerning the number of their interaction partne...

We analytically study the role played by the network topology in sustaining cooperation in a society of myopic agents in an evolutionary setting. In our model, each agent plays the Prisoner’s Dilemma (PD) game with its neighbors, as specified by a network. Cooperation is the incumbent strategy, whereas defectors are the mutants. Starting with a population of cooperators, some agents are switche...

This document is the final report on the definition of the inter-RAN cooperation schemes, initiated in the deliverable D4.1. It includes the mechanisms and techniques for the efficient cooperation among heterogeneous radio access networks (RANs), with focus on the cooperation between the WINNER RAN and legacy RANs specifically GSM/GPRS/UMTS and IEEE 802.11. The report has three main parts. The ...

Localization and tracking of moving nodes via network navigation gives rise to a new paradigm, where nodes exploit both temporal and spatial cooperation to infer their positions based on intraand inter-node measurements. While such cooperation can significantly improve the performance, it imposes intricate information processing that impedes network design and operation. In this paper, we estab...

To further study the influences of nodes failure on the total fitness degree and the cooperative ratio in cooperation network, we established the cooperation network model firstly, and then, the update rules of individual strategy and the rules of networks selfrepair are constructed. The process of self-repair in cooperation network under nodes failure is analyzed by the agent-based simulation ...

At the moment, 14 European Talent Centres belong to the recently formed European Talent Support Network, which, in the long run, can bring new dimensions to pan-European cooperation in supporting young talented people all over Europe.  Exchange and adaptation of best practices, spread and application of scientific results, possibilities of mutual visits of young talents, their teachers, me...

The employment of the network coding, combined with distributed FEC coding, in cooperative transmission schemes leads to a more efficient use of the additional time-frequency resources required by cooperation, i.e. by allowing a single relay node to serve two or more user terminals. This paper proposes a low complexity cooperation algorithm which employs network and distributed channel coding t...
