Congestion control mechanism based on data delivery probability in DTN data dissemination network by Yi XIA, Guang-hong DENG

“…A congestion control mechanism based on data delivery probability (CCM-DP) was proposed to work out the decline of data delivery performance on account of data congestion in delay tolerant networks (DTN) network coding-based data dissemination process.Considering the node mobility model,data delivery probability and data congestion degree,the data delivery probability model was constructed,and the congestion control mechanism was designed from two aspects,on the one hand,by the means of adjusting the packet forwarding process,it equilibriums the data packet delivery to avoid node congestion caused by too many packets received; and on the other hand,through the design of efficient discarding strategy,it reduces the impact of packet loss caused by data congestion.Ultimately,it was put into use in data dissemination process and some simulations were taken,the simulation results show that,CCM-DP can improve data delivery performance in data congestion environment.…”

Multi-authority attribute-based encryption access control model for cloud storage by Zhi-tao GUAN, Ting-ting YANG, Ru-zhi XU, Zhu-xiao WANG

“…The existing attribute-based encryption access control studies are mostly based on single authority,and this scheme is apt to be under attack to cause exposure of secret keys.Thus,a multi-authority access control model PRM-CSAC is proposed.Based on CP-ABE method,a multi-authority attribute-based encryption scheme is designed to improve security level.Minimized attribute grouping algorithm is designed to distribute keys to users according to needs,which can reduce unnecessary attribute key distribution and decrease the amount of re-encryption attributes.The read and write attribute are added to strengthen the control of owners.The analysis shows that the proposed scheme can meet the security requirement of access control in cloud,and it also has less response time and system cost.…”

Loop interference suppression based on space projection in full-duplex MIMO relays by Ji-song YANG, Hao LIU, Chen SUN

“…The system model including base station,full duplex MIMO relay and user station was established,and then obtained the loop interference matrix.While the case that loop interference signal's maximum multipath delay was greater than the symbol period was taken into account,signal space projection filters were designed to suppress the loop interference according to the space expanded by loop feedback interference matrix.Confronted the loop interference ma-trix full rank or not,filter design was based on subspace projection or null space projection algorithm.It was discussed that the projection algorithm how to influence the residual interference signal and the bit error rate of the relay station.Theoretical analysis and simulation results prove that the proposed space projection algorithm has ideal effect on sup-pressing loop interference.…”

Communication between nodes in backscatter-assisted wireless powered communication network by Jie TAO, Haijiang GE, Minyuan WU, Qike SHAO, Kaikai CHI

“…At present, there is almost no design on information transmission between the nodes in wireless powered communication network.The high-throughput information transmission between the nodes in backscatter assisted wireless powered communication network was studied.A scheme was proposed which consisted of backscattering/energy transmission phase and active communication phase.The maximum throughput was modeled as a convex optimization problem.Then, based on the relationship between the total backscatter communication duration and the threshold of node energy capture duration, the problem was decomposed into several sub problems that only need to optimize two backscatter durations.An efficient two-level golden section search algorithm was designed to solve the sub problems, and the optimal solution of the original problem was obtained from the optimal solutions of the sub problems.Simulation results show that, compared with pure active communication scheme and pure backscatter communication scheme, the proposed scheme can effectively improve the throughput.…”
