Using game theory for power and rate control in wireless ad hoc networks

To attain an optimum network performance, a game theory approach is the best tools that may be used to model the interaction among independent devices in order to design the state-of-the-art communication protocol for wireless ad hoc networks, which are characterized by the complexity of mobility and traffic models, the dynamic topology, and the unpredictability of link quality. In this paper, we describe how various interactions in wireless ad hoc networks can be modeled as a game. To be more specific, we use a game-theoretic approach to specify how to efficiently use locally transmit power and assign optimally the transmission rate. The criterion of optimality is the stability of the underlying communications protocols, carrying out our proposed joint power and rate control scheme. By computer simulations, we investigate the performance of proposed scheme assuming the wireless ad hoc environment and show our simulation results in terms of utility, goodput, and power consumption.
