> 中文摘要: 研究了IEEE 802.11 PCF(point coordination function)机制下集成实时业务和非实时业务的性能,提出了一种新的实时业务准入控制算法.该算法根据网络中的非实时业务负载情况动态计算准入阈值,并对准入的实时业务结点按服务指标进行轮询,从而在对实时业务提供参数化QoS(quality of service)的同时,使非实时业务吞吐率保持在可接受的水平上.仿真实验验证了算法的有效性.
Abstract:In this paper, the performance of integrating real-time and non real-time traffic in the PCF (point coordination function) mode of IEEE 802.11 is studied, and a novel real-time traffic admission control algorithm is proposed. By changing the admission threshold dynamically according to the current load of non real-time traffic and polling the admitted real-time nodes according to their service index, the proposed algorithm can provide parameterized QoS (quality of service) for real-time traffic, while at the same time, keep the throughput of non real-time traffic at an acceptable level. The validity of the admission control algorithm is verified by simulation.
