    RSS-TOA based localization algorithm in non-line-of-sight environment by Zhigang LU, ·ouming LI, Xianghong JIA, Shengming CHANG, Xiaoli WANG

    Published 2019-09-01
    “…The existence of non-line-of-sight (NLOS) error can degrade the positioning performance in wireless sensor network localization system,especially in indoor localization.To overcome the localization error caused by NLOS propagation,a localization algorithm was proposed based on received signal strength (RSS) and time-of-arrival (TOA).Firstly,a non-convex optimization problem was established based on RSS and TOA.Then,the original non-convex optimization problem was transformed into a convex optimization problem through the second-order cone relaxation technique,therefore a sub-optimal solution to the original problem could be obtained efficiently.Finally,computer simulation results show that the proposed method can provide higher estimation accuracy and better performance.…”

    RSS localization algorithm based on second-order cone programming in non-line-of-sight environment by Xiaoping JIN, Jun LIANG, Shaofeng XIE

    Published 2021-03-01
    “…Aiming at the problem that the accuracy of localization using received signal strength (RSS) in wireless sensor network is insufficient in non-line-of-sight (NLOS) environment, a new robust localization algorithm based on second-order cone programming (SOCP) was proposed.Based on the assumption of the upper bound of NLOS biases, a location equation with robustness to NLOS biases was constructed to suppress the interference of NLOS biases, then convex optimization was used to transform the robust localization problem into a second-order cone programming problem with the intention of accurate estimation, thereby improved the localization accuracy.In addition, the localization problem was extended to the case of unknown transmission power, and an iterative SOCP algorithm was proposed.Simulation results show that the proposed algorithm can effectively solve the problems existing in NLOS localization, and the localization accuracy is better than Newton iteration method, UT method and SOCP method.…”

    A hybrid indoor localization algorithm based on RSSI and inertial navigation by Yaping ZHU, Weiwei XIA, Yueyue ZHANG, Feng YAN, Xuzhou ZUO, Lianfeng SHEN

    Published 2017-10-01
    “…To cater for the requirements of high-precision indoor localization algorithms,a hybrid indoor localization algorithm based on received signal strength identification (RSSI) and inertial navigation was proposed.This algorithm used fingerprint identification algorithm to localize the agents,based on the RSSI values of ZigBee nodes in wireless sensor network.The algorithm combined the inertial information provided by inertial measurement units (IMU),to correct the RSSI localization results.This algorithm used Kalman filter and adopted state equations to describe the dynamic change rules of agents’ positions,thus it achieved a hybrid localization algorithm which relied WSN localization first and IMU last.Simulations evaluate that the proposed algorithm can improve the localization performances of algorithms which adopt RSSI localization and inertial navigation individually,and can greatly improve localization accuracy.…”

    Deployment scheme of WSN relay nodes based on artificial bee colony optimization by Kainan LIU, Xu HAN

    Published 2016-09-01
    “…In wireless sensor network(WSN),the relay node deployment performance is one of the main factors to affect network life.Aiming at the WSN with 3-demension high density,there is no existing relay node deployment schemes enhancing the network life efficiently with the constraints of hardware cost and network connectivity.Hence,a novel deployment scheme called artificial bee colony(ABC)-based relay node deployment scheme(ABC-RNDS)was proposed based on network-grid deployment method.In ABC-RNDS,double-layer topology was adopted to build WSN,which used minimum spanning tree to construct the backbone nodes of WSN,and applied ABC to extend the network lifetime by optimizing network parameters and constraining the number of relay nodes.The simulation results show that,compared to the traditional deployment scheme,ABC-RNDS can improve network lifetime significantly under constrains of cost and connectivity.…”
