Abstract Smartphones and tablets including phone, calendar and others are the necessities of modern man. They are one of the MN (Mobile Nodes), each with wireless network capabilities. Necessities of modern human MNs are almost included in every cellular module available in LTE/3G and Wi-Fi module for high-speed Internet.

They are one of the MN (Mobile Nodes), each with wireless network capabilities. Necessities of modern human MNs are almost included in every cellular module available in LTE/3G and Wi-Fi module for high-speed Internet. Until now, MN mobility management is handled in a traditonal way, but network-based mobility management is used in this paper. Then, carriers can manage and maintain the network for low-cost. In addition, this work considered the fact that a large number of users use the Wi-Fi and LTE/3G, with Cross-Layer-Based handoff. Read More Read Less

In this paper, the requirements of the graphic editor in the electrical automation monitoring system are analyzed in detail. The electrical automation monitoring system requirements, puts forward the key technology of software -based architecture. Net platform and the Model-View-Controller (MVC) design the pattern to design and develop the technical scheme and the graphics editor, editor of graphic management and chart module integration are used as the center. In accordance with the system view layer, control layer and model layer order, the detailed design s completed for each layer and put forward. It has the good expansibility, maintainability and reference value of power graphics editing system model. On the basis of demand analysis and the detailed design, the realization of the main view fast refresh the mouse on the graphic visualization operation. Through the drawing the library and database, the document retrieval model emerged. The realization of graphics system is able to provide a good graphical user interface. The user can conveniently draw the wiring diagram of power system network, draw and modify the graphics for the hierarchical management. The user according to site requirements of the primitive equipment in drawing on the wiring diagram, use the mouse operation, and can complete the power system calculation. The input parameters and equipment elements of primitive modeling parameters are stored in a database. The database has a good generality and contains the electric power system analysis and calculation of the required information. Read More Read Less

Through the actual case of the implementation of the large state-owned oil enterprises, the chemical laboratory information management system construction, from the demand for research analysis is detailed. The system outline design, system detailed design, system testing and system operation maintenance, and several aspects elaborated the petroleum chemical industry information management systems methods and processes. This paper first analyzes the process characteristics of the operation and management of laboratory, research the internal staff demand, and explains the necessity of the construction of the system; secondly, combined with the laboratory, business needs and business situation, the study analyzed a set to conform to the laboratory work flow characteristics. Third, the laboratory information management system of the specific implementation plan is addressed. Then the analysis of the overall structure of the laboratory information management system, detailed design, specific design ideas and methods of database, sample testing process, management process, management reporting, data queries and other functional modules are studied. Finally, the paper summarizes and analyzes the advantages of the laboratory management information system in the practical application in petrochemical enterprises. Read More Read Less
