    Multi-level feedback based time synchronization algorithm for wireless sensor networks by HUANGFU Wei1, ZHOU Xin-yun1, CHEN Can-feng3

    Published 2009-01-01
    “…Aiming at the fast and efficient time synchronization protocol for the wireless sensor networks under resource constraints, a novel feedback-based full-scale time synchronization(FTS) algorithm was proposed.The basic idea of FTS is to execute iteratively time synchronization downlink operations on all the nodes of the wireless sensor network and collect the two-way path delay information from only a part of nodes to calculate the average delay adjustment per hop.The stochastically feedback scheme is adopted to reduce the uplink packets.The FTS algorithm also consists of the mechanisms of synchronization error monitoring and clock skew correction.The FTS was implemented on the popular TelosB sensor nodes from UC Berkeley.The experiments show that FTS is a fast, resource-efficient algorithm with ra-tional synchronization precision.…”

    Analysis and verification on space probe performance of 2-D spectrum estimation algorithm by Ting LI

    Published 2016-05-01
    “…According to the analysis requirement of the space probe performance of 2-D spectrum estimation algorithm,a brief introduction of the 2-D spectrum estimation algorithms was given in the view of calculating speed,calculating volume,stability,accuracy and practical application.These algorithms were the spectrum estimation algorithms of the 2-D MUSIC,the 2-D interference and the 2-D MEMP with the L-shaped array.The estimation performance of the algorithms were analyzed by simulations,the angle root mean square error of three algorithms were compared and analyzed.Simulation results show that the performance of the 2-D MEMP is the best,the performance of the 2-D interference algorithm is the worst,and the performance of the 2-D MUSIC is moderate.Meanwhile,the experimental scene was constructed,and the space probe performance of the 2-D spectrum estimation algorithm was analyzed by real data.The experimental results were consistent with the simulation results.Based on this,the 2-D MEMP algorithm may be further applied in the radar and TT&C system.…”

    Multi-target localization algorithm based on adaptive grid in wireless sensor network by Tianjing WANG, Xiuqin LI, Guangwei BAI, Hang SHEN

    Published 2019-07-01
    “…The RSS-based multi-target localization has the natural property of the sparsity in wireless sensor networks.A multi-target localization algorithm based on adaptive grid in wireless sensor networks was proposed,which divided the multi-target localization problem into two phases:large-scale grid-based localization and adaptive grid-based localization.In the large-scale grid-based localization phase,the optimal number of measurements was determined due to the sequential compressed sensing theory,and then the locations of the initial candidate grids were reconstructed by applying l<sub>p</sub> (0< p<1) optimization.In the adaptive grid-based localization phase,the initial candidate grids were adaptively partitioned according to the compressed sensing theory,and then the locations of the targets were precisely estimated by applying l<sub>p</sub>optimization once again.Compared with the traditional multi-target localization algorithm based on compressed sensing,the simulation results show that the proposed algorithm has higher localization accuracy and lower localization delay without foreknowing the number of targets.Therefore,it is more appropriate for the multi-target localization problem in the large-scale wireless sensor networks.…”
