Required resource for nodes in an ad hoc network with specific parameters (e.g. node-count and topology) is one of the most important problems for the manufacturer. In this paper, in the first phase, we showed that according to the proposed game model for the node behaviour, the network converge to a steady state and in the second phase, the process of a node in forwarding the received packets is modeled as a queue system and according to the load of a node the required resources (e.g. buffer-size and average service rate).
