基于移动距离的最佳接入点配置研究

Optimal Access Point Configuration Based on Moving Distance

为在无线网络传输过程中同时满足部署成本最小、信号之间干扰不强等要求,提出基于移动距离的最佳接入点配置(OAPC)方法。该方法在遵循802.11g通讯协议标准的前提下可获取最佳接入点配置。通过观察WiFi使用者的有效行为,创新性地以使用者移动距离为一定分析指标,探讨在无线网络情况下,WiFi使用需求对移动距离是否会产生干扰。利用MATLAB软件对接入点实验数据进行仿真。当WiFi使用需求均匀分布且配置接入点数量为一个时,求得OAPC算法资源配置标准误差为1.313 4m,而对比算法FKNN标准误差为1.417 9m,幅度提高7.37%。因此可以看出,采用OAPC算法使移动距离接入点的资源配置性能更加稳定。

Optimal access point configuration based on moving distance (OAPC) is proposed in the process of wireless network transmission to meet the requirements of minimum cost and weak disturbance between signals. This study obtains the best access point configuration. under the system of 802.11g communication protocol standard. Through effective observation of the behavior of WiFi users and the innovation of taking the users ' moving distance as a certain analysis index, we discuss whether the WiFi usage demand will have certain interference to the moving distance in the case of wireless networks. Based on the above analysis, this paper simulates the experimental data of the access point through MATLAB software. When the WiFi usage demand distribution is evenly distributed and the number of configured access points is one, the standard allocation error of the OAPC algorithm is 1.313 4m. The standard error of the comparison algorithm FKNN is 1.417 9m, and the amplitude is increased by 7.37%. Therefore, it can be seen from the data results that the resource allocation performance of the mobile access point using the OAPC algorithm is more stable.
