Mobile agents:
Mobile agents are programs that can jump from host to host at times and to places of their own choosing.
Mobile agents have the potential to save bandwidth, reduce latency, and increase server availability for many applications.
Useful in several military scenarios (see other posters).

No long-lived connection.
Results (see other posters):
Mobile-agent systems can scale well, and we know how to do it.
Mobile-agent systems can interoperate through CoABS Grid.
Market-based control can allocate resources to traveling agents, and agents can plan their usage effectively and efficiently.
Models of bandwidth savings show when to use mobile agents in wireless networks.
