Abstract
A game theoretic approach is applied for studying the energy efficient rate scheduling. The individual utility function is defined first. Then, a non cooperative rate game is modeled in which each user decides the transmission rate to maximize its own utility. The utility function considered here is the consumed energy for the individual user’s data transmissions. In particular, using the fact that the utility function is convex, we prove the existence of Nash Equilibrium in the energy efficient rate scheduling problem at hand. Accordingly, a non cooperative scheduling algorithm is provided. For better energy efficiency, the sum of the individual user’s utility function is optimized. ∙제1저자 : 오창윤 ∙교신저자 : 오창윤 ∙투고일 : 2014. 5. 16, 심사일 : 2014. 6. 26, 게재확정일 : 2014. 8. 1. * 인하공업전문대학 정보통신과(Dept. of Information and Communication Engineering, Inha Technical College) ※ 이 논문은 2014학년도 인하공업전문대학 교내연구비지원에 의하여 연구되었음. 56 Journal of The Korea Society of Computer and Information August 2014 Finally, the convergence analysis and numerical results to show the energy efficiency of the proposed algorithms are provided. ▸
