Abstract: Since published, the Android 4.2 has received a great deal of attention. Relative to the Android 4.1, the Android 4.2 adds many new features. Supporting Wi-Fi Display is one of the new features added in the display part of Android 4.2. Wi-Fi Display means Video sharing realization by Miracast. The paper about a method realized video sharing by Miracast based on Android4.2 Set-top box. First of all, introduced the development background and the concept of the Miracast; then, particularly introduced the way of video sharing based on Android 4.2 Set-top box; finally, discussed the future development prospect of Miracast.

Abstract: Performance-based navigation (PBN) is a new navigation technology which proposed by ICAO, It uses satellite navigation technology to guide the aircraft to fly, but in practice the final approach track and the track design there is a certain bias. This paper analyzes the reasons for the existence of track deviation and uses Bessel geodetic algorithm to calculate track parameters, the results show that the method is simple and practical, which can effectively reduce track deviation, and can be reduced to the navigation accuracy error tolerance specification within the range.

Abstract: Through the study, we found computer has powerful ability to analyze management in the colorful painting field.Spread of the mobile terminal augmented reality is a hot field in today's society technology development, composite is a new kind of create immersive virtual scene technology. Introduced the advantages of mobile terminal transmission of augmented reality and real life, the application of augmented reality and the mobile terminal transmission is discussed.

Abstract: It has been general recognized that the application of localization technology in home environment are beneficial to the development of health monitoring and mobile identification system development. As a kind of highly efficient sensor with obvious advantages such as low cost, the Bluetooth device has been widely used in our daily life. Research is carried out in an integrated environment based on mobile phone network signal measurement and Bluetooth link measurements in developing home localization systems. This paper presented a hybrid classification method, based on the combination of Bayesian network and supported vector machines, to support the development of Bluetooth-based room localization system. The proposed method mainly considers the dependency between features and non-linear overlapping of features between rooms. The results show that the prediction accuracy has been improved greatly in comparison to the traditional Naive Bayes classifier and the hidden Markov model used in previous studies.

Abstract: In order to solve the problem of growing massive of data in sensor network, we propose a new scheme of data storage for sensor network based on HDFS which is a cloud-based storage platform, it effectively alleviate the pressure of mass data storage on sensor network, and improved the scalability of storage system and part of the enhanced the data storage security on sensor network. And this scheme is based on cloud storage platform, storage the data which collected by sensors to each data node using a distributed architecture solution, and keep multiple copies of data in order to maintain its high reliability of data. As reducing the pressure of data storage, but also protects the security of stored data as shown by security analysis.

Abstract: With the rise of the Internet of Things, Android phones with its unique advantage of being open for us to provide more quality and convenient technological achievements. The research is based on the Android mobile phone Bluetooth controlled smart car design, based on mobile platforms, by means of Bluetooth technology, design and implementation of a wireless remote control car new solutions. Control platform designed for mobile phones, Bluetooth communication module, motor drive modules and other hardware modules remote control car. Realize the car forward, backward, turn left in front, front right turn after turn left, turn right after the other real-time control functions. For the remote control toy car design presents a new way of thinking, and can for the future smart home remote control designed to provide some reference value.

Abstract: Voice intercepting is an important method of the national security sectors to obtain criminal intelligence. This approach is secret, mandatory, statutory, and technical and commits a violation of privacy. The recent years of technical advancement enable criminals to adopt more sophisticated anti-investigation tools and thus impose stricter requirements on energy consumption and environmental adaptation of the intercepting systems. Zigbee is an emerging two-way wireless communication technology characterized by low power consumption, high capacity, low costs, short delays and great reliability. Hence, it is particularly suitable for automatic and remote control and can be built into any devices.

Abstract: As a result of rapid development, the Internet has become an indispensable tool in people's daily life, and web logs have been growing rapidly as well. How to deal with massive logs timely and extract information people need from the logs has become a problem; handling web log by single computer can not meet people's needs any more. Combining cloud computing and Hadoop technology, this paper established a new processing system for the collection of logs and remote parallelization analysis, which not only solved the issues of traditional systems that data handing and collection could not proceed simultaneously, but reduced the performance bottleneck of computing power and storage capacity, thereby saving much time and improving efficiency significantly.

Abstract: Order-preserving encryption (OPE) scheme is a deterministic symmetric encryption scheme whose encryption algorithm produces ciphertexts that preserves numerical ordering of the plaintexts. The cryptographic study of OPE was initiated by Boldyreva, Chenette, Lee, and ONeill [1]. They proposed an OPE scheme based on a sampling algorithm for the negative hypergeometric distribution (NHGD). In this paper, we present the security analysis of NHGD-based OPE and the proof procedure of efficiency.

Abstract: ZigBee technology is widely used in wireless sensor networks with the advantages of low power, low cost, convenient networking, etc. Design of ZigBee-based wireless sensor network nodes have become a demand. The nodes are generally placed in some occasions where the power supply inconvenient and require battery-powered, so the low-power of the nodes is an important indicator. The node chose CC2530 as the hardware core and transplanted Z-Stack protocol stack. It collected different data through different sensors and used ZigBee technology for wireless communication. This article describes the process of node hardware design, and reduces the power consumption of the node with choosing low-power devices, reducing the operating frequency and other methods. Low-power node saves the cost and increases the life of the nodes and the network. So it is good for increasing the continuity and stability of the network.
