摘要
针对端对端通信多用户间的资源竞争问题,提出基于非合作博弈的端对端通信系统资源分配算法.首先以干扰最小化为目标构建博弈的效用函数,并充分考虑各种用户间的干扰;然后构造该博弈的潜在函数,并分析纳什均衡的存在性;最后通过仿真实验分析算法的有效性和优越性.结果表明,相对于其他算法,该算法加快了收敛速度,提高了系统的吞吐量,保证了用户竞争资源的公平性,增强了干扰的鲁棒性.
Aiming at the problem of interference between device to device communications for multiple users,a novel resource allocation algorithm of device to device communication system based on game theory is proposed in this paper.Firstly,utility function of game is constructed by minimizing interference,and interference between different users is fully considered,and secondly,potential function of game is constructed and Nash equilibrium is analyzed,at last,the validity and superiority are analyzed by simulation experiment.The results show that compared with other algorithms,the proposed algorithm can speed up convergence rate and improves throughput to ensure fairness of users competitive resources,and enhance robustness of interference.
