摘要
Abstract
Aiming at the problems of intensified air port competition conflicts and uncontrollable transmission delay caused by the dense deployment of multiple access points in the fiber-to-the-room(FTTR)C-WAN2.0 architecture,a collaboration-enhanced distributed channel access(Co-EDCA)mechanism with multi-AP was proposed.The interfer-ence domain isolation was achieved through conflict graph modeling and time slot allocation,and the competition win-dow was dynamically adjusted using reinforcement learning to optimize the competitive behavior of multiple SFUs.Simulation results show that the proposed mechanism can reduce the conflict probability by 23%,improve the system throughput by 98%,and reduce the transmission delay by 57%in SFU-dense scenarios,effectively solving the resource competition and quality of service guarantee problems under the C-WAN2.0 architecture.关键词
