This presentation considers non-cooperative slotted ALOHA (S-ALOHA) games, in which two users contend for the channel by taking one of two actions, i.e., transmit or wait. We first show an achievable (expected) payoff region of the games with mixed strategy and its Nash equilibria (NE) as a closed form, in which two users want to fulfill their own payoff demand. By extending two-user game into N-user game, we show an asymptotic equivalence between game-theoretic approach and the conventional approach of maximizing throughput. We further examine the correlated equilibria (CE) of this game and discuss the limit of S-ALOHA game.
