Compressive sensing based data gathering algorithm over unreliable links in WSN by Ce ZHANG, Xia ZHANG, Ou LI, Guan-lin MEI, Zhe HAN, Da-long ZHANG, Guang-yi LIU

“…To solve the problem that the ubiquitous unreliable links in the WSN influence the performance of the compressive sensing (CS) based data gathering,first the relationship between the reconstruction SNR of CS-based data gathering algorithm and the bit-error-ratio (BER) were simulated quantitatively.Then classify two cases were classified,namely light-payload and heavy-payload,relying on the analysis of wireless link packet loss characteristics.The random packet loss model was conceived to describe the packet loss under light-payload scenario.Further the neighbor topology spatial correlation prediction-based CS data gathering (CS-NTSC) algorithm was proposed,which utilized the nodes spatial correlation to reduce the impact of error.Additionally,the node pseudo-failure model was conceived to describe the packet loss occurred in network congestion,and then the sparse schedule-aided CS data gathering (CS-SSDG) algorithm were conceived,for the purpose of changing the sparsity of measurement matrix and avoiding measurements amongst the nodes affected by unreliable links,thus weakening the impact of error/loss on data reconstruction.Simulation analysis indicates that the proposed algorithms are not only capable of improving the accuracy of the data reconstruction without extra energy,but also effectively reducing the impact affected by the unreliable links imposed on CS-based data gathering.…”

Covid-19, Congregational Worship, and Contestation over ‘Correct’ Islam in South Africa by Goolam Vahed

“…In the absence of a central doctrinal authority the Ulama terrain is highly com-petitive and fraught with antagonistic doctrinal differences. It remains to be seen whether these divisions will boil over into physical confrontation among Muslims, and, with trust in the state dissipating, how Muslims will manage their relationship with the secular state…”

Secure performance analysis of WCDMA systems over correlated Nakagami fading channels by Guangqiu LI, Zhanwan WANG, Tingjie REN, Shuaishuai LIU

“…In order to evaluate the security performance of wideband code division multiple access (WCDMA) over multiple-input and multiple-output fading channels,a time-saving and efficient solution is theoretical analysis.The exact analytical expressions of the non-zero security capacity probability and the security outage probability of WCDMA systems using space-time block codes and 2D Rake receivers (2D-Rake) on the relevant Nakagami fading channels was deduced.Using the above expressions,the effects of parameters such as the number of transmit and receive antennas,antenna correlation coefficient,Nakagami fading coefficient,and average path attenuation coefficient on the security performance of the WCDMA system could be quickly evaluated.The numerical calculation was in good agreement with the simulation results,which proved the correctness of the above theoretical analysis.The analytical expression of the asymptotic safety outage probability of WCDMA system was deduced.The results show that the security diversity gain of WCDMA system is the sum of the diversity gains on the separable paths of the main channel,and has nothing to do with the eavesdropping channel; the same for the constant multipath intensity profile The Nakagami fading channel is distributed,and the security diversity gain of the WCDMA system is the product of the number of received and transmitted antennas of the primary channel,the number of multipaths,and the Nakagami fading coefficient.…”
