Abstract: Fluctuating load whose main inducement is the vast variety of station density and the large-scale degree surge of data collision is one of the direct reasons to bring low throughput and stability.The authors analyze the data collision avoidance mechanism of wireless local area networks,and then design the treating techniques of overcoming the effects of fluctuating load when they investigate the reasons of causing load fluctuating and the mechanism of effects of fluctuating load for wireless local area networks.Based on constructing the math model and the experimental circumstance,the authors validate the functions of these strategies by simulation whose result is discussed finally.

Key words: load, fluctuating, Wireless Local Area Networks(WLAN), mechanism, treating technique

摘要: 负载波动是引起无线局域网络吞吐量和稳定性低的直接原因之一,其主要诱因是站点接入密度的大幅度变化和数据冲突程度的剧烈振荡。分析了无线局域网络的数据冲突避免机制,在探究负载波动的原因及其对无线局域网络影响机理的过程中提出相应对策,通过构造数学模型和建立实验环境,仿真验证了所设计策略的效果,对仿真结果进行了分析。
