Transportable Information Agents

Transportable agents are autonomous programs. They can move through a heterogeneous network of computers migrating from host to host under their own control. They can sense the state of the network, monitor software conditions, and interact with other agents or resources. The network-sensing tools allow our agents to adapt to the network configuration and to navigate under the control of reactive plans. In this paper we describe the design and implementation of a transportable-agent system and focus on navigation tools that give our agents autonomy. We also discuss the intelligent and adaptive behavior of autonomous agents in distributed information-access tasks.
