Abstract

Most mobile agents are migrated to many mobile agent systems by the sequential node migration method. However, in this case, if some problems such as host´s fault or obstacle etc. happened, mobile agent falls infinity wait or orphan states. Therefore, it is difficult to get an expectation effect as use of other distribution technologies because the required time for networking between nodes increases. And so, many researches have been performed to solve this problems. However, most of methods decide node migration based on passive routing table or detour hosts which have some problems. Actually, the researches for reducing the total required time for networking are insufficient yet. In this paper, to reduce the requiredtime for networking of mobile agent we design an active routing table based on theinformation of implemented objects which are registered in the meta-table of naming agent. And also, for user´s keyword, we propose an replication model that replicates many agent object according to the information and number of object references corresponding to meta-table. Replicated objects are migrated to mobile agent systems in parallel and it provides minimized required time for networking.
