Application of Game Theory for Cross-layer Design in Cognitive Wireless Networks

Power control at the MAC layer in multi-hop transmissions and interference limited link rates of cognitive wireless networks is an important task in cross-layer design. This paper examines the per-node optimal transmission power such that the resulting power consumption may help provide better service in transmission. We examined optimal transmission of power using game theory and analyze the conflicting nodes to achieve the energy efficiency. In this paper, the proposed power saving model is examined with game models to achieve energy efficiency. We show that the game models are useful in optimum utilization of energy of cross-layer design.
