    Optimization and research on RFID anti-collision algorithm based on adaptive multi-dimension division code by Zhi-jin LI, Jie ZHOU, IAO-Jie Q, Wen-juan WU

    Published 2013-09-01
    “…Under the circumstance of many tags and many collisions,when multi-dimension division code algorithm is applied,the average number of times the reader calls each tag C(n) approximated to a limit 4/3,and the data conveyed by calling each tag tends to be a relatively small constant.However,under the circumstance of few collisions,the average number of times the reader calls each tag and the average data conveyed were relatively large.The adaptive multi-dimension division code algorithm,and the optimization of adaptive multi-dimension division code algorithm were proposed.The adaptive multi-dimension division code algorithm could adaptively decrease the MDDC dimensions according to the numbers of tags,and encode the tags again,hence greatly decrease the average number of times the reader calls each tag even under the circumstance of few tags.Therefore,in RFID system,adaptive multi-dimension division code algorithm can significantly improve the efficiency of searching for tags no matter in many collisions or in few collisions.…”

    Research on timing method for single intersection in transportation Internet of things based on improved Webster algorithm by Lin MA, Fuyang CHEN, Bin JIANG

    Published 2018-12-01
    “…Aiming at the timing signal problem of single intersection,a timing method based on the improved Webster algorithm in transportation Internet of things was proposed by combining the micro level analysis method with the macro level analysis method.In order to optimize the saturation and signal control delay,the average delay model was established.The game model and the conflict model were established with non-signal control and signal control.And the conflict analysis was carried out to illustrate that the optimal signal timing could coordinate the conflicting traffic flow.Based on the improved Webster algorithm,the shortest time required for the motor vehicle to pass the single intersection was additionally considered and a three-step optimization method for timing method at single intersection was proposed to reduce the traffic delay to ensure that the vehicle could pass effectively.The simulation results illustrate the effectiveness of the proposed solution.…”

    Improved SMC cardinality-balanced multi-Bernoulli forwardbackward smoothing track-before-detect algorithm by Jiazheng PEI, Yong HUANG, Yunlong DONG, Xiaolong CHEN

    Published 2019-08-01
    “…For the tracking problem of multiple maneuvering targets in radar observation,the sequential Monte-Carlo cardinality-balanced multi-Bernoulli track-before-detect (SMC-CBMeMBer-TBD) algorithm is inaccurate in the estimation of the number of targets and the precision of state estimation.An improved algorithm based on SMC-CBMeMBer forward backward smoothing track-before-detect algorithm was proposed.In the algorithm,the multi target particle swarm optimization (MOPSO) was added between the process of prediction and update,and the fitness function was set up based on the observation value to make the particle set move to the position of the larger posterior probability density distribution,and solve the particle poverty in the heavy sampling process.In the update step,the algorithm was used.Then the smoothing recursive method was added,and the arithmetic operation time was prolonged,but the number and the state estimation precision were improved.The simulation results show that compared with the CBMeMBer-TBD method,the proposed algorithm improves the accuracy of the estimation of the number of maneuvering targets and the accuracy of the target state estimation.…”

    Relay selection algorithm based on selfish behavior analysis in ultra-dense D2D by Yijun WANG, Youxu ZHANG, Dakun LIU, Guifen CHEN

    Published 2021-04-01
    “…In ultra-dense D2D communication, the current relay selection schemes mainly assume that the relay device has the initiative to participate in data forwarding, but some rational relay devices may delay or refuse to forward due to their own considerations, thus affecting the user experience.From the perspective of selfish behavior of relay devices, a method to identify selfish relay devices in D2D communication was proposed, and then an ultra-dense D2D relay selection algorithm based on selfish behavior analysis was proposed.Firstly, three relay identification attribute factors, namely joint interest degree (JID), forwarding history ratio (FHR) and relay physical state (RPS) were defined, and their weights were calculated by triangular fuzzy function to identify relay devices with selfish behavior.Secondly, based on the TOPSIS (technique for order of preference by similarity to ideal solution) method, the final relay equipment selection scheme relay was realized.Simulation results show that the proposed algorithm can identify selfish relay devices more effectively in D2D communication.Compared with other relay selection algorithms, the proposed algorithm has made significant progress in the aspects of D2D communication forwarding success rate, system average throughput and average time delay.…”
