Cooperation among nodes is one of the main concerns in Ad hoc network; and success or failure of a network depends on the rate of cooperation. In this paper, incentive patterns to stimulate nodes for cooperation is reviewed, then it is focused on reputation-based schemes and a survey on some of available techniques is performed. In the next step, the indicated schemes are evaluated based on com...

We study the problem of the emergence of cooperation in dynamic signed networks where agent strategies coevolve with relational signs and network topology. Running simulations based on an agent-based model, we compare results obtained in a regular lattice initialization with those obtained on a comparable random network initialization. We show that the increased degree heterogeneity at the outs...
