This paper focuses on sharing the costs and revenues of maintaining a public network communication structure. Revenues are assumed to be bilateral and communication links are publicly available but costly. It is assumed that agents are located at the vertices of an undirected graph in which the edges represent all possible communication links. We take the approach from cooperative game theory a...

Cooperative diversity is an innovative approach to improve the reliability of communication. Although this technique is considered in the next-generation mobile communication standards, it has its own challenges in practice. For example, in simultaneous transmission-based cooperative protocols, perfect synchronisation of nodes is very hard to realise. The traditional time division multiple acce...

The discovery of catalytic RNA molecules (ribozymes) capable of catalyzing a significant number of diverse chemical reactions suggests that an RNA world preceded the DNA-RNA-Protein world we know today. The self-replication of RNA molecules would be the central process of the RNA world.However, a single selfreplicating RNA would not sustain information on its own if it surpassed the “error thre...

In part II of our investigation of the multi-pair bidirectional relay network which consists of one base-station, multiple (say m) terminal nodes and one relay, all of which operate in half-duplex modes we extend and enhance previously derived protocols to exploit over-heard side information through end-user cooperation. That is, each terminal node communicates with the base-station in a bi-dir...

This paper proposes a new model, based on the theory of nonlinear dynamical systems, to study the evolution of cooperation in arbitrary complex networks. We consider a large population of agents placed on some arbitrary network, interacting with their neighbors while trying to optimize their fitness over time. Each agent’s strategy is continuous in nature, ranging from purely cooperative to pur...

In this paper, we numerically investigate the robustness of cooperation clusters in prisoner's dilemma played on scale-free networks, where the network topologies change by continuous removal and addition of nodes. Each removal and addition can be either random or intentional. We therefore have four different strategies in changing network topology: random removal and random addition (RR), rand...

Opportunism and cooperation have emerged as powerful techniques for increasing throughput in a wireless network by exploiting the broadcast nature of the medium. In this paper we use simple Markov Chain models, augmented by simulation, to investigate the benefits of using opportunism and cooperation rather than traditional hop-by-hop, fixed-path routing in a multi-hop wireless mesh network. We ...

Abstract: In order to solve the cooperation of autonomous agent systems,an artificial immune network cooperation algorithm is proposed,which is based on Jerne’s idiotypic immune network hypothesis. A sheepdog herding problem is taken as an example. The relative position information of dogs with the sheep and sheep pen is taken as an antigen. Dogs’ action is taken as an antibody. We calculate an...

Network reciprocity has been widely advertised in theoretical studies as one of the basic cooperation-promoting mechanisms, but experimental evidence favoring this type of reciprocity was published only recently. When organized in an unchanging network of social contacts, human subjects cooperate provided the following strict condition is satisfied: The benefit of cooperation must outweigh the ...
