    Indoor positioning algorithm based on effective AP selection and multi-class LDA by Guiqi LIU, Zhihong QIAN, Hualiang LI, Jiani SUN, Yinuo FENG, Xue WANG

    Published 2021-11-01
    “…To solve the problems of the lack of longitudinal position information in indoor positioning, an indoor positioning algorithm based on effective AP selection and multi-class LDA was proposed.In the offline stage, the AP selection algorithm based on stability and difference was used to extract effective AP set in the fingerprint area, and the multi-class LDA algorithm was adopted to train the fingerprint data of effective AP set at different heights to obtain longitudinal position information recognition model.In the online stage, the AP information alike the offline effective AP subset was input into longitudinal position information recognition model to obtain recognition result, and then the online fingerprint plane positioning was completed by the positioning algorithm based on the fingerprint database partition.Simulation results demonstrate that the accuracy of the proposed algorithm for determining longitudinal floors can reach 98%.…”

    Research on hybrid dynamic load balancing algorithm in heterogeneous hierarchical wireless networks by NING Guo-qin1, ZHU Guang-xi1, PENG Lie-xin1, LU Xiao-feng1

    Published 2007-01-01
    “…A hybrid dynamic load balancing algorithm based on the combination of channel borrowing scheme and load transfer scheme was proposed.The hotspot cells can borrow channels from homogeneous cells with light workload in the compact pattern.At the same time,some ongoing calls can be transferred from hotspot cells into the overlapping hetero-geneous cells with light workload according to certain conditions.The number of borrowed channels and transferred on-going calls per load balancing period was computed by the remainder available channels and new calls arrival rates in the hotspot cell.Simulation results show that the proposed hybrid dynamic load balancing algorithm can decrease the block-ing probabilities,dropping probabilities of hotspot cell system and overall heterogeneous system,the channel utilization of overall heterogeneous system is increased accordingly.…”
