Admission Control Scheme for Multi-Priority in Self-Organized Networks

摘要: 提出了一种适用于无线自组织网的多优先级接纳控制(admission control)方案。基于单跳自组织网络的带宽分配,推导了带宽预测函数和保证已接入流服务质量(QoS)的带宽上限值,为不同接入等级的业务提供接纳控制。该方案能保证网络中实时业务流的QoS,防止由于流数的增加导致QoS降级,同时也保证尽力而为业务能分享信道的剩余带宽。仿真结果验证了接纳控制方案的有效性。Abstract: In this paper, we present a novel admission control scheme for multi-priority self-organized networks. Based on bandwidth allocation scheme, we calculate the bandwidth prediction function and two upper bounds that guarantee the quality of service (QoS) of admitted real-time flows. The proposed scheme protects the throughput of active flows and prevents QoS degradation due to flow's number increases. Simulation results show the proposed admission control is feasible.
