Load balancing multipath routing protocol for mass remote sensing data downlink in LEO satellite network by Pei-long LIU, Hong-yu CHEN, Song-jie WEI, Hao CHENG, Shuai LI, Jun-yong WANG

“…LEO satellite networks can provide seamless real-time data communication for all kinds of users,which developed rapidly in recent years.At the mean time,the massive payload data down-link system of space data sources,such as remote sensing satellites,still make use of traditional storage and forward mode.The real-time performance of space mission data will be improved effectively,if such satellites are connected to LEO satellite networks equipped with inter satellite links.However,it is necessary to design a specialized satellite network load balancing routing algorithm.Satellite parallel edge-disjoint multipath routing protocol (SPEMR) was designed for remote sensing satellite real-time down-link applications.OPNET simulation results indicate that the performance degradation index(DI) of the multipath scheme implemented by SPEMR is 0.32,which is only 32% of the TLR and 21% of the traditional DSP scheme.It is demonstrated that SPEMR has the better capability of transmitting massive data in real time.…”

Trajectory differential privacy protection mechanism based on prediction and sliding window by Ayong YE, Lingyu MENG, Ziwen ZHAO, Yiqing DIAO, Jiaomei ZHANG

“…To address the issues of privacy budget and quality of service in trajectory differential privacy protection,a trajectory differential privacy mechanism integrating prediction disturbance was proposed.Firstly,Markov chain and exponential perturbation method were used to predict the location which satisfies the differential privacy and temporal and spatial security,and service similarity map was introduced to detect the availability of the location.If the prediction was successful,the prediction location was directly used to replace the location of differential disturbance,to reduce the privacy cost of continuous query and improve the quality of service.Based on this,the trajectory privacy budget allocation mechanism based on w sliding window was designed to ensure that any continuous w queries in the trajectory meet the ε-differential privacy and solve the trajectory privacy problem of continuous queries.In addition,a privacy customization strategy was designed based on the sensitivity map.By customizing the privacy sensitivity of semantic location,the privacy budget could be customized to improve its utilization.Finally,the validity of the scheme was verified by real data set experiment.The results illustrate that it offers the better privacy and quality of service.…”

Research of the Influence of Structure Parameter on the Mechanics Property of Heavy Vehicle Drive Axle Housing by Ni Jinshang

“…To solve the problems of high design margin and high manufacturing cost of heavy vehicle drive axle housing,the parametric finite element model of heavy vehicle drive axle housing is established,through the drive axle housing of key structure parameters are set for the analysis variables,the influence of the structure parameter variables on the heavy vehicle drive axle housing mechanics characteristic is researched by using static,dynamic and fatigue life method,the reference for the design and choice parameters for the heavy vehicle drive axle housing is provided.The results show that the axle housing body length and the axle housing both sides of the baffle plate distance increase,the maximum stress value and deformation value of drive axle housing will increase;the axle housing body length and the axle housing around both sides of baffle plate distance of two parameters have less influences on natural frequency of driving axle housing,and the distance of the center line of the spring seat has great influences on natural frequency of drive axle housing.…”

Research on the control strategy of multi-port DC/DC energy router for the energy Internet by Wenzhong MA, Guancheng LI, Kuitong ZHANG, Shujuan YANG, Mengdi WEI, Yuzhen TANG, Yucheng SONG, Lei DONG

“…The characteristics and shortcomings of the current multi-port direct current (DC) to DC (DC/DC) energy router were analyzed.A multi-port DC/DC energy router for the energy Internet was optimized and designed.Through the analysis of the operating voltage requirements under different working conditions,the full-bridge proportional design of the sub-module was proposed.On this basis,an alternating current (AC) to DC (AC/DC) decoupling control strategy to realize riding through the DC fault without de-blocking any devices was proposed.The multi-port DC/DC energy router was used to realize the interconnection of multiple DC power grids with different voltage levels.It not only retained the advantages of low cost and low loss of the traditional DC autotransformer,but also effectively improved the shortcomings that the DC autotransformer cannot ride through the DC fault.Finally,the simulation test was carried out in the MATLAB/Simulink environment to verify the stability of the technology in the normal operation,the feasibility of suppressing the DC fault and the effectiveness of the control strategy.…”

A massive MIMO-OTFS robust transmission scheme for vehicular networks using sensing-assisted communication by Weidong WANG, Hui GAO, Xin SU, Limin XIAO, Shiqiang SUO, Qiusha GONG

“…For a multi-user integrated sensing and communication system in the network of vehicles, a robust sensing-assisted communication massive multiple-input multiple-output (MIMO) orthogonal time frequency space (OTFS) transmission scheme was proposed.Due to the limited sensing accuracy of the radar, errors existed in the channel state information (CSI) reconstructed based on sensing parameters.The transmission performance decreased as a result.To address this issue, the CSI in the delay doppler domain was reconstructed based on the sensing parameters by the transmitter firstly.And a robust beam forming scheme was designed considering the CSI error.Secondly, the channel estimation error and inter user interference were perceived by receivers based on sensing parameters.Then the robust receiver was designed by incorporating the perceived interference errors into the signal detector in an analytical way.Finally, numerical simulation results show that the proposed method effectively reduces the system bit error rate and increases the data reception rate of users.The proposed method improves the overall system performance in this situation.…”
