Key node decision algorithm based on local information and energy factor in wireless sensor network by Bin LIU, Ya-jing SUN, Hao-ran LIU, Rong-rong YIN

“…In the existing key node decision methods for wireless sensor network,the judgment index was so single that the result judged was deficient.In order to solve this problem,a new key node decision algorithm(KNDA)based on local information and energy factor was proposed.Firstly,the local information model based on the degree and neighbor information of node was established.Secondly,according to the residual energy of node and the change of network energy consumption after the node failed,the models of energy factors were established.Finally,an aggregative key node decision model was formed.Extensive simulation experiments were carried out in the MATLAB simulation platform,by comparing with other algorithms,the results verify that the key nodes obtained by this algorithm are more sufficient.Meanwhile when the key nodes judged by KNDA are protected,the network can show strong invulnerability.…”

Self-organized CAC mechanism adopting for self-similarity service in wireless network by Lei FENG, Wen-jing LI, Xue-song QIU

“…To improve the access capacity in wireless network with the QoS ensuring,the service similarity in the wireless network was researched,and the service bandwidth was calal with similarity and QoS parameters.Then an SS-CAC (self-organized based on network similarity call admission control) mechanism based on the service bandwidth optimization was introduced to lower the system bandwidth utilization and service rejection probability.And the novel mechanism was achieved and simulated.Compared with traditional CAC,the results of simulation show the performance of SS-CAC mechanism can not only ensure the quality of the voice service but also reduce the bandwidth utilization of the data service by 2.69%.In addition,it can also reduce the call rejection ratio and call drop ratio by 0.95% and 2.81% respectively in the case of high cell load.…”

Research on the invulnerability of regional network based on topology analysis by Changqing AN, Yujia LIU, Hui WANG, Zhiyan ZHENG, Tao YU, Jilong WANG

“…To measure the overall impact of different attacks a network region may encounter, an evaluation algorithm can be used to capture the difference in invulnerability of regional network topologies.Specifically, the vulnerability of regional network and that of connection topology between regions both internally and externally was analyzed.To find predictions between regions as supplemental topology data and create the Internet topology, data would be measured in various ways and verified.Using stratified probability sampling, multiple damage simulations could predict the worst-case scenarios in real conditions.Damage was simulated multiple times based on stratified probability sampling to approximate the damage situation of the area under real conditions.A significance tester was realized to measure the impact of damage from the overall level and special weak points respectively, discover the difference of the damage between the areas, and calculate the regional invulnerability ranking.Finally, the ranking and clustering results of forty-eight regions were given.…”

Study of multiple frequency-offset and channel joint ML estimation over virtual multi-antennas OFDM system by JIANG Jian, JIANG Hua, YAN Kai, LIU Hai-tao

“…A pilot-aided joint estimation of the carrier frequency offsets（CFO） and channels of a virtual multi-anten-nas（VMA） orthogonal frequency-division multiple（OFDM） system was considered.For a VMA-OFDM system,each pair of transmit and receive antennas possibly having a different CFO and CIR（channel impulse response） parameters made the parameters joint estimation a challenge task.By utilizing the series expansion of the matrix inversion and maximum likelihood（ML） criterion,a computationally efficient estimator allowing for simultaneously estimating the unknown pa-rameters was developed.The mean square-error（MSE） performance of the interested parameters for the proposed estima-tor was compared with the Cramer-Rao bound（CRB）.In addition,the pilot sequence design was investigated by analysis and simulations.Simulation results show that the proposed low-complexity estimator asymptotically achieves the CRB and overcomes the drawbacks of existing estimators.…”
