The Research On Remote Accessing Model To Digital Home Based On Mobile Agent

With the development of infomation technology,as well as people's living standard, people have been pursuing safer, more comfortable, and more intelligent home as their goals. Consequently, people are changing their notion of house decorating and making Digital Home a tendency.However, there still lies some problems in Digital Home -- absence of an identical family network standard, difficulty in constructing an integrated system with diferent products, low intellectualized degree and high cost. In recent years, the technology in mobile agent has provided an breakthough in this isomeric network. As a potential agent technology, Mobile Agent technology has a characteristic of mobility and aptitude,and it combine with network management technology can remarkably increase flexibility and scalability. years, Mobile Agent technology is considered to be an easily to design, realize and maintained new technology under Intemet/Intranet environment, and becomes the research hot point in academic and business communitiesMobile Agent is a kind of software entity which can move freely in Internet.It is in dependent of machine and can move from one machine to another, and completes the task on behalf of the user. Mobile Agent technology involves the computer network, the distributional system,the artificial intelligence and many other kinds of domains.Because the characteristic of mobility, independency and coordination, it has already applied in the Internet environment,and demonstrated huge prospect and superiority.The main purpose of this thesis is to explore concrete application of mobile agent technology to construct Digital Home and study some problems and their solutions when we apply mobile agent technology in software development. The software development method based on mobile agent was analyzed in detail after having studied the basic concepts and application characteristics of mobile agent.Then a remote-accessing model in Digital Home system was proposed. This thesis elaborates the software agent concept, and gives an integrity introduction to essential techniques,the technicals uperiority and security of mobile agent's structure Then it describes an information service model bas ed on mobile agent, and proposes a remote-accessing model in Digital Home system based on this foundation.The subsystem's constructions and their reciprocity have been analyzed; The thesis explores in detail the mobile agent soft development kit Aglet and its programming mechanism, elaborates the Aglet event model and the message transmit mechanism, which provide key support for the correct programming.Using Aglet as development platform and unifying other technologies, we have implemented this model . It is proved in the experiment that the remote accessing based on mobile agent shows great superiority .The response time is very short and network bandwidth usage little.
