Design And Implementation Of Scene-Based Mobile Social Network System

With the development of Internet and the increasing popularity of mobile terminals, mobile social network service (mobile SNS) has greatly developed. Scene life system is a scene-based mobile SNS system in wireless environment. Combined with current edge-cutting technologies, this system embodies basic conceptions of SNS and provides corresponding solutions to some issues for better use experience and service, including user interface, access control, and user data privacy protection, and so on.Start from overall design, this thesis specifically presents the album module, the communication module and the game module of the client in the system. Scene life system realizes the browsing and creation of scene, the browsing of album, the display of friend list, the function of a game and many other functions, and it provides users with new experience of touch-screen devices. Firstly, technologies related with scene life system are introduced, including Six Degrees of Separation,150 Rule, augmented reality technology and D-BUS technology, etc. Secondly, demand analysis and runtime environment of the system are described. Thirdly, the design of system architecture is proposed based on demand analysis, and details of design solutions of the system are presented. After that, the implementation of main modules of the client is given.This thesis focuses on discussing the overall design of scene life system and implementation of some modules on the Maemo platform. It introduces the building of Maemo platform environment, the program development and the method to package. Also, the interfaces and implementation methods of album module, communication module and game module are described in detail. Finally, through analyzing the result of the system test, the functions of the system is validated, and it is proven that the function and performance of the system meet the design requirements.In the end, the summary of the whole thesis, current shortcomings of the system and future work are given. Also, the summary of my work and research progress during master-degree study are described.
