A game theoretic approach to joint resource management in wireless ad hoc networks

Wireless Ad hoc network consists a set of mobile or immobile nodes. This network provides wireless services for different nodes without any fixed infrastructure. Quick and economical deployment of ad hoc networks yields its well desirability for different applications. One of the most significant issue in resource management of wireless ad hoc networks is power control. It should be done in a rational way to alleviate interference across the network. Efficient power control saves the batteries as well as guaranteeing a minimum level for SINR to satisfy QOS requirements of all nodes. In this work we propose a new approach based on game theory to change rate, modulation and power in the game algorithm. All users are satisfied of incorporating the game rules. Selfishness of autonomous users are bounded consequently under this framework. It implies the game reaches to the desired point called Nash equilibrium point. Through various numerical results, we show that all users have a tradeoff between benefit maximization and transmission power minimization, considering rate and modulation in their strategies.
