Network Optimization Algorithm Based on Power Control and Channel Assignment by Yue Liu, Xiaolei Guo, Xun Zhang

“…WLAN has been massively deployed in various places.However，the poor user perception of network quality，or even dropping line，unable to connect to the network and other issues.For this case，a network optimization algorithm based on power control and channel assignment was proposed.The algorithm uses the method of power control and channel assignment to optimize the WLAN in a specific range，maximize the effective bandwidth of WLAN，and ensure the balance of network load at the same time.Simulation experiments show that the network optimization algorithm of the power control and channel assignment has achieved the aim of improving network performance.…”

A quadratic weighted centroid algorithm for tunnel personnel positioning by Haiying Wang, Linhao Liang, Jian Xu, Hui She, Wuxiang Li

“…Compared with the centroid algorithm, the Min-Max multilateration algorithm, and the weighted centroid based on distance algorithm, the simulation results showed that (1) the positioning performance of the quadratic weighted centroid algorithm was superior to the other three algorithms; (2) when the reference nodes were symmetrically arranged, the positioning accuracy was higher than a fold line layout; and (3) when the lateral reference node spacing was extended from 20 to 30 m, the average positioning error met positioning accuracy requirements, which could reduce overall system costs.…”

WLAN indoor positioning algorithm based on skewness-kurtosis testing by Zhen-long SONG, Gang-yi JIANG, Chao HUANG, Mei YU, Jia-le ZHANG

“…Focused on the issues that large positioning errors produced by the inconsistency of received signal strength (RSS)sample population distributions under indoor wireless local area network (WLAN),an indoor positioning algorithm based on skewness-kurtosis testing was proposed.By using the testing method of skewness and kurtosis,whether the RSS samples come from the normal population or not was checked.The distribution functions of the samples accepting null hypothesis were approximated with normal distribution,and the probability density functions of the samples refusing null hypothesis were estimated by kernel function.Experimental results show that the proposed algorithm leads to a 15 percent improvement over the previous methods.Moreover,the proposed algorithm can significantly reduce the workload of the off-line phase at the same positioning accuracy.…”
