Call Admission Control Based on Resource Sharing in LTE-Advanced Relay System by Jihong Zhao, Haifang Han, Hua Qu

“…A call admission control based on resource sharing in LTE-Advanced relay system was proposed.If the shared resources of the target site for new users and handover users are used up，handover users can use the reserved r esources of the target site for handover users to access system，while new users can access system by resource sharing between the sites in the cell which the target site inside.Simulation results show that compared the proposed algorithm with LTE-Advanced system on fixed bandwidth reservation scheme and LTE-Advanced relay system on fixed bandwidth reservation scheme，the proposed algorithm can effectively reduce the blocking probability of new users and dropping probability of handover users in the cell，and can improve the system resource utilization.…”

Design of key technologies for intranet dynamic gateway based on DPDK by Fucai CHEN, Weizhen HE, Guozhen CHENG, Shumin HUO, Dacheng ZHOU

“…Aiming at the problems of high packet processing delay and high overhead caused by IP hopping,active defense gateway system with multi-layer network deployment structure was designed and implemented based on the data plane development kit (DPDK).Firstly,based on the DPDK fast forwarding framework,forwarding and processing performance of the system were optimized.Secondly,for the dynamic random mapping gateway with three different types of IP addresses,an efficient IP address allocation algorithm and an unpredictable IP address conversion algorithm were designed.The experimental results show that the designed system can effectively reduce the rate of information acquisition of sniffing attack,while greatly improving the processing delay caused by dynamic hopping.…”

Coordinated beamforming for cognitive multi-cell networks with wiretap channels by Dong-hua CHEN, Xiu-xiu ZHANG, Wei-bo XIE

“…Owing to the coupling among the vectors to be optimized，the problem becomes non-convex and non-linear.Accordingly，a centralized coordinated beamforming design method was proposed by constraining the leakage interference and using the semi-definite relaxation，and on the base of it，a decentralized algorithm was also proposed by decomposing the centralized design problem into a group of sub-problems on each cell’s base by using dual decomposition.Simulation results show that the proposed schemes make effective reduction in power consumption while guarantee the legal users’ secrecy rate requirement and the cognitive interference constraint.Moreover，the proposed decentralized method not only reduces the computational complexity，but also has the same performance as the centralized algorithm.…”

Assessment of Urban Water Supply System Based on Query Optimization Strategy by Shibao Lu, Yizi Shang, Wei Li, Zhimin Wang

“…The results show that the validity and convenience of all reduction algorithms involve the whole query process. An algorithm is independent of the chart of static characteristics and can realize all reduction states without depending on analyzing the benefits from intermediate semijoin results, which will ultimately contribute to reductions in the transmission of useless data in the network and communication costs. …”

Accurate calculation of the content volume, density and original weight of museum curated eggs by Valeriy G. Narushin, Michael N. Romanov, Nili Avni-Magen, Darren K. Griffin

“…We found a negative correlation between D i and S/V (which reflects the egg metabolism level) and suggest that a female in most species maintains the duration of egg incubation at a constant level that has practically an unchanged value for the respective species. A mathematical algorithm for calculating the D i value depending on the S/V ratio provides the missing link in calculating W of a whole egg from archived collection material.…”
