Lunar gravity filed determines the optimization design of lunar orbiters and selections for landing sites. Direct gravity measurement by deploying high-resolution gravimeter is the only option for obtaining precise local gravity data rather than the satellite gravity survey. However, there are both light-weight and shock-resistance demands for payloads of lunar landers. Therefore, this paper proposes a Micro-Electromechanical-Systems (MEMS) based gravimeter for lunar gravity survey, taking the advantages of both light and robust. The basis of this MEMS lunar gravimeter is: a silicon-based spring-mass system performs as the gravity-sensitive element. When gravity varies with locations or time, the spring length will change and so the displacement of mass. Using the optical displacement measurement technology, the gravitational acceleration can be worked out. The gravity-sensitive element requires both an extremely low fundamental frequency for a higher sensitivity and lower noise floor and large spurious resonant frequencies for low cross-sensitivities. Shock-resistance structures are required for robustness of the gravimeter. According to the above design rationales, the gravity-sensitive element is designed and the finite element analysis software COMSOL has been used to simulate the vibration modes of the spring-mass system with the beam width varying from 20µm to 30µm. The gravimeter design with a beam width of 24µm has a fundamental frequency of 5Hz. The mechanical thermal noise can be worked out as 0.3µGal/Hz1/2 under the room temperature and atmosphere with a quality factor of 200. The equivalent noise of the optical displacement transducer is 10µGal/Hz1/2. Hence, the overall noise floor of the MEMS lunar gravimeter is 10µGal/Hz1/2, which can meet the requirement of precise measurement of lunar gravity field.

Wireless Sensor Network (WSN) is a popular research field in recent years. This paper focuses on node placement of WSN applications, as monitoring physical value (e.g., temperature) or tracking paths of moving objects in surrounding environment. Inspired by anti-aliasing theory in sampling field, we present a Poisson-disk Sampling (PDS) based strategy for WSN node placement. With the theory of sampling, we study the spectral properties of node distribution, in order to reduce the deviation of data collection result. Simulation results show that PDS outperforms other placement methods, such as regular and random strategies, in terms of monitoring surrounding environment. In addition, we apply the PDS-based strategy to various WSN applications and design a simple energy-saving pattern with coverage and connectivity preserved.

Quantum key distribution (referred to as QKD) is a technology that can produce and distribute secret keys unconditionally secure based on the principle of quantum mechanics. In a practical QKD system, the reconciliation efficiency is crucial to the final key rate of the system. A practical QKD system may produce the uneven error distribution of the sifted key due to the instabilities of optical and electronic devices and some other reasons, which will lead to the low reconciliation efficiency. Therefore, to scramble the sifted key is adopted in many QKD systems. In this paper, an Arnold-based Scrambling Algorithm and Fast Exchange Scrambling Algorithm are proposed mainly for the CASCADE class and WINNOW class error reconciliation algorithms. The experimental results demonstrate that the proposed algorithms provide the lower computational complexity and higher scrambling efficiency than the representative scrambling algorithm in QKD.

It is the focus of research on the navigation algorithm with high-accurated and easy-achieved for UAV. In this paper a gradient descent algorithm for AHRS of Quadrotor by using MEMS gyro, accelerometer, and magnetometer is presented. The algorithm uses a quaternion represent rotation, allowing accelerometer and magnetometer data to be used in an analytically derived and optimised gradient descent algorithm to compute the direction of the gyroscope measurement error as a quaternion derivative. Through the simulation based on Matlab software, the algorithm can significantly reduces the requirement for the processor of speed and precision, effectively fusing the data of the MEMS sensor, and achieves the high-accurated attitude calculation of Quadrotor.

In the complex hardware and software hybrid system, the rapid increase of the software scale and the system complexity bring the important challenge to the software security modeling. There are still many functional or semantic problems for traditional modeling language and modeling method, when they are used into the security modeling. Therefore, based on the Architecture Analysis and Design Language (AADL), this paper proposes the AADL error model and extracted the timing fault tree. After comprehensive analysis by using the common factor failure analysis and the hardware and software failure analysis, we can obtain the generation mechanism of danger. By establishing the AADL multi-view security model of the software system, and converting it into the Timed Abstract State Machine (TASM) and the Markov model, this paper forms a method of the security verification and evaluation based on extended AADL model. Finally, we confirm the effectiveness of the proposed method by performing security analysis for an instance.

Delay tolerant networks (DTNs) are network environments with high latency, low data rate, intermittent connection, and limited resources. The communication between the nodes is conducted through the store-carry-forward mechanism, and multi-copy routing strategy is often used to improve the reliability of communication. In order to improve the message delivery probability, reduce network overhead and manage the node buffer more effectively in DTNs, this paper proposed a dynamic energy-efficient Epidemic routing algorithm for DTNs (DERD). The algorithm utilizes the dynamic energy threshold strategy to determine whether to transmit the message from the sending node to the receiving node, the ACK acknowledgment information is incorporated in the algorithm to delete the outdated message. The simulation results show that the algorithm is superior to the contrast routing algorithm in terms of the number of survived nodes, message delivery probability and network overhead ratio.
