摘要: 本文引入显示当前子载波质量的信道状态矩阵,以系统总功耗、单个子载波上的功耗、总时延、干扰温度限和单个子载波上的次用户数等为约束条件,以能效为目标函数,建立多约束条件下的分式规划机制.设计演化博弈算子,为每个次用户建立效用函数,当每个次用户的效用函数达到最优时,演化博弈达到Nash均衡点,此时的策略组合认为是能效相对最优的资源分配状态.通过实验仿真对比,本文给出的EESA-EG(Energy Efficient Subcarrier Allocation withEvolutionary Game)算法的能效相对最优,且给出了相对最为合理的子载波分配方案,为信道状态更优的子载波分配了更多的子载波.

Abstract: A kind of novel sub-carrier dispatching approach based on game strategy for EEO (named EESA-EG) has been put forward. In this approach, we adopted the channel state matrix to show the quality of sub-carriers under the banner of relative constraint factors with the height of secondary user, the total data transmission rate limit, total power consumption constraint and power consumption constraint on a single sub-carrier. At the same time, the nonlinear fractional programming mechanism is designed to pursue the maximum of energy efficiency, which is used as the objective function. The utility function for each secondary user is set up when the game operator is developed. If the utility function reaches the optimization, the evolutionary game process will become Nash equilibrium, which is regarded as the relatively optimal energy efficient resource dispatching status. Based on our experimental tests, our proposed approach gives the relatively reasonable sub-carrier dispatching effect, which can dispatch more sub-carriers with relatively better channel state.
