摘要/Abstract

摘要： 无线接入点(AP)在公有或私有区域的不合理规划部署容易导致基本服务集(BBS)相互重叠,增加信道干扰。在帧传输前,如何准确预测信道中潜在的干扰因素并采取应对策略,成为WLAN通信技术领域的研究热点。为此提出一种WLAN信道传输干扰预测方法,即在传输期间结合块确认帧实时采集并统计A-MPDU帧传输状态信息,计算干扰发生的概率,预测信道传输干扰因素并采取有效的应对策略。仿真结果表明,所提出的方法不仅能准确预测信道传输干扰因素,还能在多种拓扑环境下进一步利用网络带宽,提升帧传输效率。

关键词: 信道干扰,A-MPDU,块确认,WLAN

Abstract: Wireless access points which are not rationally planned and deployed in public or private area lead to overlap of basic service sets (BBS) and increase channel interference easily.Before frame transmission,how to accurately predict the channel potential interference factors and adopt coping strategy become a hotspot of WLAN communication techno-logy.Therefore,a transmission interference prediction approach in WLAN channel was proposed.During transmission,the proposed approach captures and statistics A-MPDU frames transmission status information with B-ACK frames,then calculates the probability of interference occurs,at last predicts transmission interference factors and adopts coping strategy.Simulation results show that the proposed approach can not only effectively predict channel transmission interference factors,but also increase the use of network bandwidth and improve frame transmission efficiency in a variety of topological environment.

Key words: Channel interference,A-MPDU,B-ACK,WLAN
