Abstract
Since random access technology can not guarantee quality of service (QoS) requirements in general, the centralized polling-based access mechanism, such as point coordination function in IEEE 802.11, is provided in wireless network to support QoS related services. It is proved that the optimal polling scheme for symmetric systems (same traffic offered to all queues) is exhaustive polling (Liu et al., 1992). This paper proposes three gated service (3-gated) polling scheme on the basis of polling scheme. It is validated that the performance of the novel scheme is close to that of exhaustive polling by the theoretical analysis and simulation. It also shows 3-gated polling is more effective and can avoid unfairness which is inevitable for the exhaustive polling
由于随机接入技术一般不能保证服务质量(QoS)要求,无线网络提供了基于集中轮询的接入机制,如IEEE 802.11中的点协调功能,以支持QoS相关业务。证明了对称系统(向所有队列提供相同流量)的最优轮询方案是穷举轮询(Liu et al., 1992)。本文在轮询方案的基础上提出了三门控服务(3门控)轮询方案。理论分析和仿真结果表明,该方案的性能接近穷举轮询。结果表明,3门控轮询更有效,避免了穷举轮询不可避免的不公平现象
