Improving community structure strategy for efficiently enhancing Internet transmission performance by Jun CAI, Shun-zheng YU

“…An efficient weakening community structure strategy (WCS) by adding links to the existing networks was propose,which could enhance Internet transmission performance.Internet topology reconstruction could be realized by WCS strategy,because lightpaths that represent logical links between nodes could achieve the same high performance as physical links by means of optically bypassing intermediate nodes.The performance of the proposed strategy was investigated in pseudo random networks with community structure scale-free network with community structure and Internet,topology respectively,for both local routing strategy and global shortest-path routing strategy.The experimental results show that the traffic capacity of networks and the average shortest path are considerably improved by adding a few links among communities.…”

Iterative algorithm on single-channel blind separation and decoding of co-frequency modulated signals by LIAO Can-hui, TU Shi-long, WAN Jian

“…An algorithm was proposed to exploit the codes in iterative single-channel blind separation and decoding of two co-frequency modulated signals with long-constraint channel codes.The output log-likelihood ratio（LLR） values of the decoder were used as a prior LLR fed back to the separator to improve the separation performance.Special emphases were laid on soft input soft output blind separation,maximum a posteriori（MAP） decoding and LLR interaction between separator and decoder.Simulation results show that the proposed algorithm can make a significant improvement in per-formance over the algorithms without iterations.For BPSK signals with（2,1,6） convolutional codes and random inter-leaving,a gain of about 2dB in signal-noise ratio can be obtained after two iterations.…”

Pseudo chaotic pulse position modulation in UWB communications by XIANG Xin1, WANG Jie-ling2, ZENG Zhi-bin2, YI Ke-chu2, CHEN Shun-fang3

“…A novel pseudo chaotic pulse position modulation（PCPPM） was proposed which was suitable for ultrawide-bandwith impulse radio communication systems,in this scheme,symbolic dynamics of a chaotic map was used for chaotic pulse position modulation（CPPM）,the separation between the adjacent pulses were determined by chaotic dynamics and binary information was modulated onto this carrier by the pulse position modulation method.System could acquire synchronization automatically without any specific "hand shaking"protocol.The advantages of PCPPM are decrease of the measurement precision of interpulse intervals and suitable for all digital solution.Since a random distribution of interpulse intervals,the resulting spectrum is a noise like spectrum.Finally,the performances of PCPPM were analyzed and simulated.…”

Improved ant colony optimization algorithm for solving constraint satisfaction problem by HANGYong-gang Z, HANGSi-bo Z, UEQiu-shi X

“…The traditional backtracking algorithm was less efficient on solving large-scale constraint satisfaction problem,and more difficult to be solved within a reasonable time.In order to overcome this problem,many incompleteness algo-rithms based on heuristic search have been proposed.Two improvements based on ant colony optimization meta-heuristic constraint solving algorithm were presented:First,arc consistency checks was done to preprocess before exploring the search space,Second,a new parameter setting scheme was proposed for ant colony optimization to improve the effi-ciency of the search.Finally,the improved algorithm is applied to solve random problems and combinatorial optimization problems.The results of the experiment have showed its superiority.…”

Proxy re-signature scheme based on isomorphisms of polynomial by Hui-xian LI, Lu SHAO, Liao-jun PANG

“…Most of the existing proxy resignature schemes were based on the hardness of big integer factoring,discrete logarithm,elliptic curve.However,none of them can resist the attack by a quantum computer.Motivated by these concerns,a new proxy resignature scheme was proposed.By employing secret affine transformations and homogeneous polynomials,the proposed scheme could implement the signature transformation with high-efficiency,and meanwhile it was secure against the attack by a quantum computer.The results of analysis showed that the proposed scheme was correct and consistent,and had the unforgeability in the random oracle model.Compared with the existing schemes,the proposed scheme not only inherits the resistance to quantum attack and high efficiency from the multivariate public key cryptosystems,but also has the properties of multi-use,transparent and private proxy.…”

Stochastic gradient descent algorithm preserving differential privacy in MapReduce framework by Yihan YU, Yu FU, Xiaoping WU

“…Aiming at the contradiction between the efficiency and privacy of stochastic gradient descent algorithm in distributed computing environment,a stochastic gradient descent algorithm preserving differential privacy based on MapReduce was proposed.Based on the computing framework of MapReduce,the data were allocated randomly to each Map node and the Map tasks were started independently to execute the stochastic gradient descent algorithm.The Reduce tasks were appointed to update the model when the sub-target update models were meeting the update requirements,and to add Laplace random noise to achieve differential privacy protection.Based on the combinatorial features of differential privacy,the results of the algorithm is proved to be able to fulfill ε-differentially private.The experimental results show that the algorithm has obvious efficiency advantage and good data availability.…”
