Abstract

In a typical mobile agent system, the network used by the agents is constructed logically. In such a logical network, agents migrate and/or send messages to users or to other agents. Thus, the delay for agent migration and communication and the total amount of traffic for all agent activities depend on the form of the logical network. In addition, plural paths between any pair of nodes on the network are necessary, to minimize the effects of a node or link failure. In this paper, we propose a method for designing a logical network dynamically. The proposed method chooses nodes to which a new node is connected to satisfy the demands for delay and total traffic on the physical network, which may differ among various network applications. Moreover, our method works well in practice, using only local node information. Finally, the performance of the proposed method is evaluated by simulation experiments.
