A game-theoretic method for transmit power control across multi source-destination distributed wireless networks is proposed, which is viable for any number of source-destination pairs, with any number of players (or sources). A dynamic non-cooperative game is proposed to optimize packet delivery ratio (PDR) and transmit power considering a realistic signal-to-interference+noise ratio (SINR) model of the wireless channel. Here sources (or players) transmit concurrently and thus have imperfect information about other players actions. The game accounts for a limited set of discrete values for transmit power and can be applied in static, quasi-static and slow fading channels. If the SINR is feasible, each game stage has a sub-game perfect equilibrium, and the game requires fewer iterations and has faster convergence to a Pareto-efficient outcome, than other appropriate techniques such as SINR discrete power balancing and multi-objective power optimization. In this context, a novel accurate PDR model is given in terms of a compressed exponential function of inverse SINR, a function that is realistic for many IEEE 802.11 type implementations of various packet sizes and data rates, and facilitates a tractable analysis and implementation of this dynamic game.
