Abstract: The information security of wireless sensor networks is one of hot issues on the current research; this paper combines threshold key scheme with the management of security key sharing and group agreement and proposes dynamic key management scheme through clustering level key matrix of authentication mechanism from the cluster to node. The network is divided into different clusters, and the cluster head conducts the key authentication exchange and updates the key management with threshold key schemes, with no need of third authentication center, reduces the computing and communication costs, and promotes communication.

Abstract: Information can be collected search engine on the Web, but the current search engines can only interpret the characteristic structure of web page data from the perspective of syntax, is lack of semantic understanding, and thus cannot find the desired information quickly and accurately. In order to solve these problems, this paper proposes an information mining model of intelligent Collaboration based on agent technology. By analyzing the information mining process, more to understand the mechanism of Collaboration mining, thus can help users find faster and better desired information.

Abstract: In view of the practical application, this paper presents a communication system based on IOCP+JSON, using fewer threads to provide services for more users, can solve the user concurrency. Optimize a compression algorithm for JSON data to reduce the data repetition rate and network traffic consumption, apparently shorten the data transmission time and improve the system performance.

Abstract: This paper presents an intelligent urban public bike leasing system based on ARM. This system takes S5PV210 microprocessor as the core of the terminal system and constitutes the public bike rental point with Intelligent parking device connected to the CAN bus. This system based on Android, Embedded Linux operating system CAN bus and GPRS remote data transmission technology designs the hardware and the software of the terminal and designs the software of the data center using I/O multiplexing. The system guarantees the efficient operation of public bike rental, and provides more intelligent and personalized service to users.

Abstract: Course scheduling is the permutations and combinations of teachers and students in terms of time and space according to different constraints so as to make teaching proceed normally. The course scheduling of laboratories is similar to but not the same as the course scheduling of normal classrooms. This paper completes the system of course scheduling in computer laboratories with reference to the course scheduling algorithm and implementation of theory teaching. The system is running well.

Abstract: Today's network is becoming more and more multifarious, network attack and defense game between intensified, traditional network security defense schemes have been unable to effectively prevent and stop growing and complex application layer on the network attack. This scheme mainly focus on the application layer of network security, analyze the status of the application layer security, and then to vulnerability scanning to adapt to the current network environment security solutions, as well as the network security vulnerability scanning system design scheme. This scheme is applicable to medium enterprises network security planning and deployment, for enterprises in upgrading our network security, network planning and deployment time provides reference opinions.

Abstract: The paper puts forward three aspects of Intelligent Community Network. They are wired network, wireless network, and intelligent gateway. The wired network and wireless network design the structure of Intelligent Community network, and make the bandwidth requirements of backbone and subnet. At the same time, we deploy the area covered by wireless-network and where we set up the wireless hotspot. The intelligent gateway, as the core content of the Intelligent Community, has designed the connection between themselves with the intelligent terminals, and the way to transfer data based on IPv4/IPv6 to IPv6 /IPv4.

Abstract: This paper describes a smart healthcare data management system based on hadoop. Aiming at the disadvantage of Traditional management of medical data such as the increasing cost of consumption and the limited availability of the data, the smart healthcare data management system in this paper introduces a hybrid storage architecture including designs of Structured data storage which supported by RDBMS and Non-structural data storage which supported by Hadoop. This smart healthcare data management system has the advantages of low-cost, high fault tolerance, and scalability, and builds a cloud storage platform applied in the system of smart healthcare.

Abstract: CAN-bus is one of the most widely used vehicular buses, so the CAN-bus driver program was programmed to the vehicle terminal based on Android operating system in this paper. The programmed CAN-bus driver program included application software framework of car terminal, implementation of CAN-bus driver module, and call of Android hardware abstraction layer (HAL), etc. The research makes the vehicle terminal connect with the vehicle body network tightly, optimize the driving experience and the driving safety.

Abstract: This paper details the realization of the detection and control of the equipment interface using visual basic (VB) and C++ mixed programming. It discusses the attention problems and programming method of making dynamic link library and the VB called dynamic link library, and an example is presented to detect and control the device interface, using VB to call the dynamic link library can realize the detection and control of the bottom interface, it solved the problem that VB language cannot realize the detection and control of input and output interface. This method has universal significance for the design of control system.
