Design and implementation of a layer-II fast handoff protocol in emergency communication system by Fang-min LI, Le ZENG, Yi SHEN, Tao ZHANG

“…Immobility,limited bandwidth and poor support to real-time service are common shortcomings in traditional emergency communication system.Moreover,the data transmission speed is highly limited in high-speed services by the long handoff delay and fixed handoff trigger threshold when the mobile terminals moving between network nodes.In order to overcome these shortcomings,a new emergency communication system with multifrequency hierarchical clustering structure was designed.A new layer-II fast handoff protocol was designed for such network structure to deal with handoff issue in real-time services.In this handoff protocol,the handoff trigger threshold is self-adaption based on the moving velocity of mobile terminals.…”

A Speech Recognition Method Using Competitive and Selective Learning Neural Networks by Hu Guangrui Xu Xiong Yan Yonghong

“…In this paper,a basic principle called the equidistortion principle for vector clustering is theoretically derived by using Gersho’s asymptotic theory,and a new competitive learning algorithm is prorosed with a selection mechanism,called the CLS（Competitive and Selective Learning）algorithm.Because the selection mechanism enables the system to escape from local minima,the proposed algorithm can obtain better performance without a particular initialization procedure.A new neural network algorithm with competitive learning and multiple safe rejection schemes are proposed in the context of parallel,self organizing,hierarchical neural networks（PSHNN）.The input of PSHNN is a subset of the output scores of HMM.The experimental results indicate that the recognition ability of the method based on competitive learning neural network is higher than that of the traditional HMM method.…”

Self-configuration power scheme for femtocell base station by Peng XU, Xu-ming FANG, Zheng XIANG, Rong HE

“…To solve the issue that new femtocells deployed in hierarchical networks would introduce a series of interference,a power self-configuration scheme was proposed.Various kinds of interference that femtocell base station might receive from other base stations were analyzed.Then an optimal power issue was formulized,as was able to maximize the femtocell system capacity on the condition guaranteeing the existing users'normal communication.And the optimal solution was also obtained with lagrange multiplier method.The simulation results show that the proposed scheme cuts down the transmit power of femtocell,increases the throughput and reduces interference for existing users,comparing with the scheme based on received signal strength.…”

Decentralized credit system based on blockchain and its application by Mingsheng WANG, Heyang CAO, Peiyao LI

“…A decentralized credit system was proposed and its construction application was given.Decentralized credit system could be constructed by expanding the transaction structure of “digital currency commodity” based on block chain,expanding the function of consensus protocol and adding specific accounts.Also,the decentralized credit system was applied to the PKI enhancement and supervision system IKP so that IKP system did not need global fund in operation.Moreover,by introducing the hierarchical “virtual currency commodity” supply adjustment mechanism in the decentralized credit system to alleviate the difficulty of regulating the “virtual currency commodity” supply of “digital currency commodity” based on block chain,the precise “virtual currency commodity” supply regulation can be achieved.…”

Research on mapping method of logical carrying network across multiple domains by Min ZHANG, Chun-ming WU, Bin WANG, Ming JIANG

“…In order to solve the mapping problem of logical carrying network across multiple domains,a hierarchical linear program model was presented,which aims to minimize the cost of mapping.Based on this model,a mapping algorithm for logical carrying network across multiple domains was designed using primal decomposition and subgradient optimization technique.The correctness of this method was proved by theoretical analysis,and the validity of the proposed method was assessed by a collection of numerical simulation experiments through the performance of convergence and runtime,as well as mapping request acceptance ratio and revenue in a dynamical network environment.…”

Multi-cell multi-user downlink beam forming design considering transceiver impairment by Can-feng XIA, Shi-wen HE, Yong-ming HUANG, Hai-ming WANG, Lv-xi YANG

“…Multi-cell multi-user downlink beamforming schemes considering transceiver impairments were developed,with the objective of minimizing the maximum mean square error (MSE) and the sum of MSE of all users.The optimiza-tion problem was transformed into a second-order cone programming(SOCP) standard form,and a hierarchical iterative algorithm was developed to solve the original problem.Compared with the traditional beamforming methods developed for ideal transceivers,numerical results show that our proposed optimization algorithms greatly reduce the impact of im-pairments and improve the system performance.…”

Collection policy refining method for threat monitoring in complex network environment by Fenghua LI, Zifu LI, Ling LI, Ming ZHANG, Kui GENG, Yunchuan GUO

“…Personalized collect policy is one of the necessary conditions for effectively monitoring threats in the complex network environment.However,differences in security requirements and threat types make it difficult to effectively generate personalized collect policy.To address the above problem,a collection policy automatic refinement method was designed.Firstly,a hierarchical model of collection policy was proposed.Then,by transforming the policy refinement into a nonlinear optimization problem,a genetic algorithm was designed to balance between collection revenue and collection cost.Finally,simulation experiments verify that according to the requirements of high-level monitoring,the acquisition scheme can be automatically generated.…”

Degree distribution optimization for LT codes and its application in link maintenance of cognitive radio by Benshun YI, Weiqing YAO

“…The degree distribution has a great influence on the performance of Luby transform (LT) codes.Based on the link maintain model of cognitive radio system，the novel degree distribution of LT codes was obtained by using the THOA (two-layer hierarchical optimization algorithm) to combine the IPD (improved poisson distribution) which achieved high decoding success rate with low overhead and the robust soliton distribution (RSD) which achieved high decoding success rate with high overhead.Simulation results show that the proposed method with application to link maintenance in cognitive radio system can improve the reliability and efficiency of secondary communication.…”
