Implementation of changing message migration using mobile agents

In a collaborative colony, changing message migration occurs frequently. In this paper, we introduce a concept of collaborative transaction group (CTG). Intra-group transactions can share the intermediate results with one another, and this is transparent outside the group. It is required to sustain the group memberships and the consistent update of group members´ view, and to ensure such update events have the same effect on each collaborative member. Furthermore, we use mobile agents to implement the changing message migration mechanism, analyze a pluggable mobile agent platform, and put forward a mobile agent migration policy and a control model of adaptive mobile agents. We also present the implementation methods of this mechanism, while a simulation test is performed on the different scenarios with a network simulator Ns-2.
