Research Of Agent-Based Application Seamless Migration In Smart Home

Pervasive Computing is considered as a new computing model following the mainframe computing model and desktop computing model, which is intended to make computing devices and services ubiquitous in the whole physical space, and people can utilize computing services in the surrounding environment whenever and wherever , while not awaring of any computing equipment and computing services existing. Therefore, pervasive computing embodies the integration of computing, communication and digital media technology, makes computing, communication and digital media act as water, electricity, and air, and has a revolutionary impact on people's life and work.As an important application of pervasive computing, in the smart home, in order to achieve "whenever wherever and transparent access to digital services", people try to allow the mutual application migrate in the corresponding space, so that people not only can maintain a continuous conversation, but also could be given the space they are familiar with, which has positive effects on improving efficiency and customer satisfaction. The application seamless migration allows people do not care about the distribution of applications and services, but focus on the quality and connotation. Seamless migration is mainly about how to ensure seamless migration of user's tasks to a new scene will take the initiative to continue to execute, and its functional requirements is mainly embodied in the continuity of the self-adaptability and initiative.Based on the above three functional requirements, this paper puts emphases on seamless migration in the smart home, involving context-awaring computing, environment adaptation, a seamless migration method and so on, regards smart home as a test bed, treats pervasive access as an application requirement, and combines computing, communications with digital media organically, to show the new computing and application model.In addition, this paper more research on ontology modeling, parameter calculation model, context reasoning mechanisms, and active mapping between tasks and services, to better support application migration under heterogeneous network in smart home. In order to complete or more effective completion of the relocation of audio tasks, this paper adopt agent-based coalition and negotiation mechanism, and put forward a new algorithm based on dynamic combination of genetic algorithm and ant algorithm.
