Introducing cooperation into a wireless sensor network (WSN) has gained much attention in the recent few years mainly because of the significant effect it has on optimizing energy consumption and on enhancing the lifetime and the overall performance of the network. Cooperation can be exploited at different levels, ranging from a collection of nodes collaborating to forward the data they gathere...

Which social norms and networks maximize cooperation in bilateral relationships? We study a network of players in which each link is a repeated bilateral partnership with two-sided moral hazard. The obstacle to community enforcement is that each player observes the behavior of her partners in their partnerships with her, but not how they behave in other partnerships. We introduce a new metric f...

Purpose – This paper maps out multi-agency partnerships in the UK information assurance (UKIA) network in the UK. Design/methodology/approach – The paper surveyed members of the UKIA community and achieved a 52 percent response rate (n=104). The paper used a multidimensional scaling (MDS) technique to map the multi-agency cooperation space and factor analysis and ordinary least squares regressi...

Evolution of cooperation is a fundamental question of socio-biology. Intrinsic factors like kinship play an important role in cooperation among selfish individuals. External factors like uncertainty and the structure of the social interaction network also contribute significantly to the evolution of cooperation. Here I use agent-based simulations to generate artificial social networks. I show t...

Metanorms is a mechanism proposed to promote cooperation in social dilemmas. Recent experimental results show that network structures that underlie social interactions influence the emergence of norms that promote cooperation. We generalize Axelrod's analysis of metanorms dynamics to interactions unfolding on networks through simulation and mathematical modeling. Network topology strongly influ...

We introduce a community network model which exhibits scale-free property and study the evolutionary Prisoner’s Dilemma game (PDG) on this network model. It is found that the frequency of cooperators decreases with the increment of the average degree k̄ from the simulation results. And reducing inter-community links can promote cooperation when we keep the total links (including inner-community ...

The emergence and evolution of cooperation in complex natural, social and economical systems is an interdisciplinary topic of recent interest. This paper focuses on the cooperation on complex networks using the approach of evolutionary games. In particular, the phenomenon of diversityoptimized cooperation is briefly reviewed and the effect of network clustering on cooperation is treated in deta...

Cooperative communication can achieve spatial diversity gains, and consequently combats signal fading due to multipath propagation in wireless networks powerfully. A novel complex field network-coded cooperation (CFNCC) scheme based on multi-user detection for the multiple unicast transmission is proposed. Theoretic analysis and simulation results demonstrate that, compared with the conventiona...
