Large-Scale Mobile-Agent Systems Resource Control in Large-Scale Mobile-Agent Systems David Kotz, George Cybenko, Daniela Rus, Robert Gray Dartmouth College 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). Mobile agent Data source Mobile agent Mobile agent Soldier in the field launches mobile agent which jumps through wireless links to the data source; 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.
