Along with the Accelerated Information Process of society, the application of network is increasing in the form of exponential. The former mode of distributed computation is more and more unfit to the environment of network today. In order to solve the problem, a new technique come into being, this is mobile agent. Mobile agent is the outcome of network technique and artificial intelligence.The technique of mobile agent changes the mode of data processing, which makes the program migrate to the terminal instead of the terminal data migrate to program. After the computation, mobile agent only brings the results to user. This mode reduces the unstable network's influence to distributed computation. The unstable network are caused by low-bandwidth, high time delay, etc.Through analyzing the current mobile agent platform, and comparing their strongpoint and shortcoming, we put forward some betterment on agent's migration, route and security.According to the analysis of mobile agent's migration, we will divide the mobile agent's migration into strong migration and week migration, the standard is that the migrated program starts to execute from broken point or not. The strong migration of mobile agent is one of the emphases in this paper. Through the analysis of JVM register and JVM stack, we use JPDA to capture the thread information, such as: the local variable, value of PC and so on. Then by using the technique of serialize, the mobile agent migrate to the destination. Finally mobile agent restores its state and goes on executing at the destination.The algorithm of choosing route in this paper is also a way to enhance the capability of mobile agent. We use mobile agent technique to server mobile agent's choosing route. We analyses the traditional algorithm and uses some way to discover and predigest route to improve the efficiency of choosing route, which also can improve the mobile agent's efficiency.The aim we do research is that the new technique can be applied in future, if the research' result indicate that it can't be extensive applied, the significance of research is not great. Along with mobile agent going deep into mobile computing, information search and E-commerce, etc, the security is become more and more important. So we put forward some method to solve the security of mobile agent system. In this paper, we put forward a method which is based on attribute certificate to solve the security problem.
