Authors: Xu Yuan Fei , Li Li Hong
Published: February 2014

This paper proposes a joint spatio-frequency resource model and management strategy in cognitive MIMO (Multi-Input Multi-Output) systems by exploiting the spatial signal processing ability provided by multi-antenna techniques. With the scheme cognitive system could coexist with the primary in one occupied authorized frequency channel without interfere with the later. Accordingly cognitive transmission could be carried out even there is no idle spectrum available. This is a complement to traditional CR in which the performance of cognitive user depends to a great extent on the availability of spectrum hole. Simulation results show that compared with conventional CR, the proposed method could effectively improve the performance of cognitive user on the premises that no interference is imposed on the primary.

Published: February 2014

A lack of centralized administrator has made communications in mobile ad hoc networks relied on cooperation of mobile nodes. Apparently, their limited energy cannot provide a sustained supply for consumption on operations, such as relaying, forwarding, etc. This may cause the self-ish behaviors of non-cooperative nodes, resulting in degradation on the stability or reliability of routing. The self-ishness worsens because of node mobility. Most existing works were considering external profits and inner motivations. In this paper, we analyzed three kinds of incentive mechanisms based on virtual currency, reputation and game theory, respectively. We compared application scenarios and performance of these mechanisms, and discussed their limitations. Finally we proposed possible directions for the future research on the incentive mechanisms in mobile ad hoc networks.

Published: February 2014

Certificate-based encryption is a new paradigm which was introduced by Gentry to address the complex public key revocation problem in traditional public key cryptosystems. It represents an interesting and potentially useful balance between traditional public-key encryption and identity-based encryption. In this paper, we introduce the notion of hierarchical certificate-based encryption that preserves the advantages of certificate-based encryption such as implicit certificate and key-escrow free while inheriting the properties of hierarchical identity-based encryption. We formalize the definition of hierarchical certificate-based encryption and also propose a concrete hierarchical certificate-based encryption scheme that is chosen-ciphertext secure under the hardness of bilinear Diffie-Hellman problem in the random oracle model.

Authors: Zhao Wen Zhe , Zhao Kai , Chen Qiu Bo , Lv Min Jie , Hou Zuo Xun
Published: February 2014

This paper concerns the design of high-speed and low-cost LDPC code bit-flipping decoder. Due to its inferior error correction strength, bit-flipping decoding received very little attention compared with message-passing decoding. Nevertheless, emerging flash-based solid-state data storage systems inherently favor a hybrid bit-flipping/message-passing decoding strategy, due to the significant dynamics and variation of NAND flash memory raw storage reliability. Therefore, for the first time highly efficient silicon implementation of bit-flipping decoder becomes a practically relevant topic. To address the drawbacks caused by the global search operation in conventional bit-flipping decoding, this paper presents a novel bit-flipping decoder design. Decoding simulations and ASIC design show that the proposed design solution can achieve upto 80% higher decoding throughput and meanwhile consume upto 50% less silicon cost, while maintaining almost the same decoding error correction strength.

Authors: Liu Ya Li , Chai Wen Yan , Li Xiu Rong
Published: February 2014

We present a pipelined parallelism approach to implement the short-range force computations in molecular dynamic simulations on a multi-core machine. Our methodology is based on the OpenMP programming model. It uses multiple producer threads and a single consumer thread to adapt the application for pipeline parallelism, and utilizes the high inter-core communication bandwidth. Multiple producer threads compute the short-range force, and the consumer thread modifies the global force-array. Compared with some other methods applied in data parallelism that can parallelize reduction operations on a force-array, our method achieves high performance especially when the simulation system is characterized by irregular geometry or by inhomogeneous atom densities.

To study the organizational structure of particles in particle swarm optimization (PSO), we have proposed the family PSO (FPSO) previously. To further study the internal structure of FPSO, this paper introduced the animal collective behavior into the FPSO. It made the interaction ruling among particles was not based on random selection but topological distance. Each family interacted on average with a fixed number of neighbors, rather than with all neighbors within a fixed metric distance. Simulations for four benchmark functions demonstrated that the interaction ruling based on topological distance among particles was more reasonable than that on random selection.

Zero Taps Detection-Based Sparse Channel Estimation Method for OFDM Systems
Authors: Zheng Xue Jiao , Jiao Jian
Published: February 2014

The channel whose impulse response contains a large number of zero taps is sparse. Exploiting the sparsity of the channel, the estimation problem can be converted into an on-off keying (OOK) detection problem. Therefore, a sparse channel estimation algorithm was proposed. First, with an initial estimate, posed a detection problem by casting the determination of non-zero taps into an OOK communication problem; then took precise evaluation against the established non-zero taps position. In the simulation, the proposed algorithm was compared to the standard LSE via simulations in terms of MSE and BER. The results show that, the proposed algorithm can provide the best performance while maintaining moderate complexity.

Chemical Reaction Optimization for Earliness-Tardiness Scheduling Problem
Authors: Cheng Chen , Tan Yue Jin , He Ren Jie , Feng Yao
Published: February 2014

This paper studies a job shop scheduling problem on a single machine environment with an objective of minimizing the total weighed earliness and tardiness penalties. Jobs have distinct release dates and distinct due dates. A sequence-dependent setup times exists between two consecutive jobs. Jobs are punished if they are finished either before due dates or after due dates. A chemical reaction optimization method is proposed to solve the problem. An improved optimal timing is applied to fix the start time of each job under given sequence. Experimental results show that the proposed algorithm can solve this problem effectively.
