    The Structure of Disjoint Groups of Continuous Functions by Hojjat Farzadfard, B. Khani Robati

    Published 2012-01-01
    “…We will show that (1) each group of the second type is conjugate, via a specific homeomorphism, to a piecewise linear group of the same type; (2) each group of the third type is a subgroup of a continuous disjoint iteration group. We conclude the Zdun's result on the structure of disjoint iteration groups of continuous functions as special case of our results.…”

    Dynamic adaptive trust evaluation model based on interaction-aware by Feng LI, Li-min SHEN, Ya-li SI, Jing-chun NIU

    Published 2012-10-01
    “…A dynamic adaptive trust evaluation model was established based on interaction-aware.The historical interaction window and trustworthy recommendation number was introduced in overall trust evaluation method,which overcomes the shortage of traditional models that lack the capacity to interaction-aware.The direct trust accumulation method based on interaction satisfaction degree iterative calculation was proposed,which achieved the incentive and penalty iterative strategy based on entity stability factor,and effectively inhibits malicious entities with camouflage.A synthetical recommendation trust aggregating method based on combination of direct and indirect recommendation trust was given,which solved the accuracy low and unreliable problems of traditional recommendation methods by introducing entity familiarity factor and scoring similarity factor.Simulation results show that,compared to the existing trust model,the model can effectively improve the accuracy of trust evaluation,and can provide a better capacity of resisting collusive entities.…”

    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.…”

    Blind adaptive matching pursuit algorithm for signal reconstruction based on sparsity trial and error by Wen-biao TIAN, Zheng FU, Guo-sheng RUI

    Published 2013-04-01
    “…Compressed sensing is a novel signal processing theory that it introduces a novel way of acquiring compressible signals,the test times of existing sparsity trial and error algorithms were always large.The novel algorithm,blind sparsity adaptive matching pursuit (BSAMP) was proposed,could recover the original signal fast in the case of unknown sparsity.Firstly,the range of sparsity was determined,and each time half of values in current range were eliminated by trial and error test.Secondly,the number of atoms was twice the sparsity,which was united with the set of signal approximation support (got by last iteration) and then reconstructed the signal by solving least-squares problems.Last but not least,the least-squares approximation was pruned by weakly matching for next iteration.The results of simulation show that the novel algorithm can reconstruct signal faster and get larger recovery probability than other similar algorithms in the same conditions.…”

    User-centric energy efficiency fairness in backscatter-assisted wireless powered communication network by Yinghui YE, Liqin SHI, Guangyue LU

    Published 2020-07-01
    “…In order to address the unfair user-centric energy efficiency (EE) problem caused by channel difference in the backscatter-assisted wireless powered communication network,a resource allocation scheme was proposed.Firstly,a mixed integer nonconvex fractional programming problem was formulated to maximize the minimum user-centric EE,subject to the quality of service and energy-causality constraints.Based on the generalized fractional programming theory,the original problem was transformed into a mixed integer nonconvex subtraction problem.With the aid of the slack variable,the proof by contradiction,the auxiliary variable and the mixed integer nonconvex subtraction problem were further transformed into an equivalent convex problem.Finally,an iterative algorithm was proposed to obtain the optimal solutions.Computer simulations validated the quick convergence of the proposed iterative algorithm,and that the developed resource allocation scheme efficiently guarantees the fairness among users in terms of EE.…”
