摘　　要：无线接入网复杂化持续加剧,无线设备数量激增.为了提升未来网络容量和资源利用率,需要设计有效的拥塞控制手段和资源调配策略,平衡子网络之间负载,促进跨域资源协同共享.为此,本文在新近提出的哈希接入协议的基础上,设计了哈希接入动态优化策略,根据网络负载状况动态调整接入参数以缓解网络拥塞,并在跨网络场景下进一步提出了负载均衡方案与资源整合再调配方案,为无线接入网整合无线资源、均衡网络负载提供了有用的方法.仿真结果表明,本文提出的哈希接入动态优化策略在保证网络稳定的同时最大化网络吞吐量,资源调配方案能有效地调配失衡的网络负载,提升复杂融合网络性能和接入公平性.The intricacy of wireless access networks continues to escalate,accompanied by a substantial proliferation in the number of wireless devices.In order to augment network capability and resource utilization,it is necessary to design effective access control and resource allocation schemes to balance traffic loads among subnetworks and promote cross-do⁃main resource coordination and sharing.To address this,our paper builds upon the recently proposed Hash Access protocol and devises an optimization method,which dynamically adjusts access parameters based on the network load to alleviate network congestion.Furthermore,this paper presents traffic balancing and resource re-allocation schemes for multi-subnet⁃work scenarios,offering valuable approaches for integrating wireless resources and offloading traffics.Simulation results demonstrate that the proposed Hash Access optimization method maximizes network throughput while ensuring network sta⁃bility,and the proposed resource allocation scheme effectively addresses load unbalancing issue,thereby enhancing the per⁃formance and fairness for complex integrated networks.
