【摘要】 本文提出了一种适用于无线局域网,可以有效处理突发实时性语音通信业务的自适应轮询机制。该自适应轮询机制只需要在接入点设置一个轮询队列并运行简单的轮询队列管理算法,算法的核心思想是对终端轮询次序的合理调整,以及对休眠终端的检测和相应处理。仿真表明,该自适应轮询机制可以有效提高无线局域网对实时语音业务的容量以及整体服务质量。更多还原

【Abstract】 A self-adaptable polling scheme for WLANs, capable of operating efficiently under bursty real-time voice communications, is introduced. According to this scheme, only a simple polling list management algorithm is needed at the access point, the core of which is the adjustment of the polling sequence dynamically, and the detection and avoidance of sleeping stations. The performance of the proposed scheme is evaluated by simulation, showing that the self-adaptable polling scheme can effectively improve the capacity and quality of service of WLANs for voice communications.更多还原
