The game-theoretic model of data transmission in a network of a given topology is presented. Two players (network nodes) tend to send as many random data packages as possible to the final nodes through one common node. Each player has a finite capacity buffer for storing data packages. A system of costs for sending and storing data packages and rewards for the successful package delivery is introduced. A dynamic conflict-controlled process is modeled as a stochastic game with a finite set of states. Existence of the Nash equilibrium and a cooperative solution is proved. The cooperative solution is a strategy profile which maximizes the total expected payoff. The price of anarchy in the network is calculated. The price compares the players’ payoffs in the Nash equilibrium and cooperative solution.
