The Research Of Routing Key Problem For Mobile Social Software System Based On Complex Networks Theory

Information technology field is a fast-update and the rapid development field, which new technologies and new ideas emerge in endlessly, the system model and the system architecture change quickly, project management, software engineering and systems development and design methods are get rid of the stale and bring forth the fresh. With the rise of the Internet, the globalization of knowledge, the development of information technology take on an "autocatalytic" speed up situation. The complexity of information systems and the development of information technology are closely related with each other, with the development of technological, information systems continually development from low-level to advanced, from simple to complex, from isolated to collaborative.In recent years, a great deal of social software expands to the mobile platform, which turns into mobile social software. A number of internationally renowned IT companies begin to apply a number of systems research methods at the research and design of general social software systems. Such as Microsoft complexity network computing group, community combined with virtual networks, software of real-time communication, dynamics that study the evolution of social network; the Collaborative User Experience Design group of IBM Research Center, which research the non-linear collaboration problem of multi-user system, applications of the analysis of social network in knowledge management; the project of Yahoo Incentive network, which study the relationships between users incentive factor and information searches in complex networks topology of social networks, and so on. However, many studies of these institution are for a specific project, pay attention to a certain aspects, and apply certain kind of system theory and methods to solve a specific problem, and not only did not regard the social software system as a complex system, but also did not consider infection of mobility for the evolution of social networks.To solve this problem, in this paper, on the basis of the existing theory and research, and the phenomena of more and more various social software expand to mobile platform and the complicated Web information systems, we introduce the theory and methods of systemic science and complexity research to information systems study, and combine systemic thoughts, systemic theory and systemic approach with analysis and architecture design of information system. Base on the above theory, we analyse the typical mobile social software, and give the definition of Mobile Sociality Software.There are more aspects in Mobile Social Software system required to study, such as constructing the model of mobile social software systems, designing clustering and transfer algorithm, researching location-based services, studying software engineering methods and modeling language ,and designing personalized optimization algorithm. The main work of this paper is as follows:First, this paper gives the definition of Mobile Social Software. Analyzing the formation and evolution of topology structure and dynamic mechanism between system components of typical Mobile Social Software system. Summed up the characteristics of existing Mobile Social Software, then introducing the complex systems theory, and give the definition of Mobile Social Software which consistent with the context of this study, but not comprehensive.Second, this paper brings a Mobile Social Software system model that based on the complex theory. On the basis of understanding the nature of Mobile Social Software and the complex systems theory, using the modeling method of local-world evolving network, to build the model of Mobile Social Software system and analyse the feature of this model.Third, improve some original transfer routing algorithm, and give a transfer routing algorithm that suitable for Mobile Social Software system. Using complex network theory and modern optimization algorithms, based on the features of mobile social software system of its own, and adding the characteristic parameters of complex system, to improve some of the original transfer routing algorithm that accord with the demand of Mobile Social Software system.Finally, this paper select a specific mobile social software systems, and statistic its complex characteristics, afterward, we use this specific systems model as a test environment for algorithm simulation.
