Multi-channel MAC protocol based on network partitioning for wireless sensor networks by Bin CHENG, Lin-lin CI, Cheng-ping TIAN, Ming-hua YANG

“…The limited amount of available orthogonal channels and noise interference are two major issues to constrain performances of multi-channel MAC protocols in wireless sensor networks (WSN).In conjunction with features of data gathering networks,a partitioning-based multi-channel MAC protocol was designed.Initially it partitioned network into several sub-trees with lower collision factor,without increasing the total value of interference around the whole network.Furthermore,it adopted a coarse-grained channel assignment strategy on basis of graph coloring theory,in order to ensure each sub-tree work on a relative optimal channel.Simulation results show that the proposed MAC protocol can significantly improve throughput and reduce end-to-end latency and packet loss.…”

Time synchronization method for wireless sensor networks based on mobile reference nodes by Yu-qiang ZHANG, Jing-sha HE, Jing XU, Bin ZHAO, Fang-bo CAI

“…Most existing time synchronization methods in wireless sensor networks depend on the existence of one or more fixed reference nodes and on the propagation of synchronization messages in the networks.Thus,they often suffer from the disadvantages of high energy consumption and large cumulative error due to multiple layers of communication.To address such issues,a new time synchronization method based on a mobile reference node and the optimal mobile path is proposed.Firstly,the cellular coverage technique is analyzed to identify the optimal synchronization points.Then,the optimal mobile path with minimal length is designed.Finally,an efficient single hop time synchronize mechanism based on multiple timestamps in the MAC layer is presented.Comparison with other methods shows that the proposed method can achieve both higher synchronization accuracy and lower energy consumption.…”

Dynamic spectrum access mechanism based on graphical evolutionary game in radio networks by Fang-wei LI, Ying-hui YUAN, Jiang ZHU

“…In order to realize efficient data transmission for users in radio networks,a dynamic spectrum access mechanism based on graphical evolutionary game was proposed for the bounded rationality characteristic of users,while graphical game can better reflect the actual game relationship among users.Meanwhile,a dynamic spectrum access algorithm and corresponding dynamic equation were designed for the mechanism to reduce the complexity of the game,and could converge to Nash equilibrium with faster speed and obtain higher system throughput and utility.Theoretical analysis showed that the dynamic equation was globally asymptotically stable,which illustrated that when user deviated because of bounded rationality and it was still able to guarantee faster converge and fewer performance deviation.Simulation comparison verifies the superiority above.…”

“…Taking structured Q -ary irregular repeat-accumulate (S-QIRA) codes as an example, the burst-error-correcting capability of QLDPC codes was analyzed preliminarily by comparison with the burst-error-correcting capability of binary LDPC codes (BLDPC)and turbo codes on the single burst e (SBE) channels and burst-deep-fading additive white Gaussion noise (BF-AWGN) channels respectively. Two criteria of designing QLDPC codes were presented for burst er-ror channels. …”

Sparsity induced convex nonnegative matrix factorization algorithm with manifold regularization by Feiyue QIU, Bowen CHEN, Tieming CHEN, Guodao ZHANG

“…To address problems that the effectiveness of feature learned from real noisy data by classical nonnegative matrix factorization method,a novel sparsity induced manifold regularized convex nonnegative matrix factorization algorithm (SGCNMF) was proposed.Based on manifold regularization,the L<sub>2,1</sub>norm was introduced to the basis matrix of low dimensional subspace as sparse constraint.The multiplicative update rules were given and the convergence of the algorithm was analyzed.Clustering experiment was designed to verify the effectiveness of learned features within various of noisy environments.The empirical study based on K-means clustering shows that the sparse constraint reduces the representation of noisy features and the new method is better than the 8 similar algorithms with stronger robustness to a variable extent.…”
