Uneven Resources network promotes cooperation in the prisoner's dilemma game

Scholars explored cooperative behavior on different network; however they did not consider the resource distribution and consumption on them. In our work, we propose a kind of uneven resource distribution network model, in which players can consume finite resources to survive. In our model, firstly, there are four players, and then we imitate real organism behavior, such as eating, migration, game, leaning, and reproduction. Meanwhile, during this process, finite resource also decreases with players’ consumption. After numerical simulation, we find that defectors can occupy the most resource-rich areas at first, but they cannot survive in hostile area and decrease rapidly. While cooperators always keep growing. In addition, when resources decrease substantially, cooperative behavior can be promoted. This also sprouts new insights on survival and development of cooperative behavior.
