| 摘 要： | 应用非协作博弈论提出一种无线局域网多用户接入控制(AC)算法.以分组发送时延作为实时用户对QoS的满意度指标,先建立AP对单用户的AC博弈模型(SAG);然后将SAG扩展为多用户AC博弈(MAG);通过求解MAG的纳什均衡,得到AP获取效用最大化的多用户接入策略。仿真结果表明,通过调整多用户接入缓冲区和AC周期的大小,MAG能够获得理想的用户接入时延;且与SAG相比,MAG能够在不影响系统吞吐量的情况下,通过优化接入用户的组合,显著地提高网络服务供应商的收益率(14%)。 |

| Abstract: | A multiuser admission control(AC) based on noncooperaitve game theory is proposed for IEEE 802.11e WLANs.Through setting the packet-sending delay based user QoS satisfaction ratio(UQS) function,the AC procedure between a user and an Access Point(AP) is modeled as a single-user game(SAG).By extending the SAG to a multiuser AC game(MAG),the Nash equilibrium of the MAG,i.e.,the best multiuser AC strategy for the AP to achieve the highest network revenue is given.Simulation results indicate that,the users’ admission delay can be well controlled by the MAG.Comparing with the SAG,the MAG has notable advantages in network revenue,while keeps the high system throughput. |
| Keywords: | IEEE 802.11e admission control quality of service game theory Nash equilibrium |
