Transportable Agents Support Worldwide Applications, David Kotz, Robert Gray, Daniela Rus
Transportable Agents Support Worldwide Applications, David Kotz, Robert Gray, Daniela Rus
Dartmouth Scholarship
Worldwide applications exist in an environment that is inherently distributed, dynamic, heterogeneous, insecure, unreliable, and unpredictable. In particular, the latency and bandwidth of network connections varies tremendously from place to place and time to time, particularly when considering wireless networks, mobile devices, and satellite connections. Applications in this environment must be able to adapt to different and changing conditions. We believe that transportable autonomous agents provide an excellent mechanism for the construction of such applications. We describe our prototype transportable-agent system and several applications.

Autonomous And Adaptive Agents That Gather Information, Daniela Rus, Robert Gray, David Kotz
Autonomous And Adaptive Agents That Gather Information, Daniela Rus, Robert Gray, David Kotz
Dartmouth Scholarship
We have designed and implemented autonomous software agents. Autonomous software agents navigate independently through a heterogeneous network of computers. They can sense the state of the network, monitor software conditions, and interact with other agents. 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 illustrate the intelligent and adaptive behavior of autonomous agents in distributed information-gathering tasks.
The Expected Lifetime Of Single-Address-Space Operating Systems, David Kotz, Preston Crow
The Expected Lifetime Of Single-Address-Space Operating Systems, David Kotz, Preston Crow
Dartmouth Scholarship
Trends toward shared-memory programming paradigms, large (64-bit) address spaces, and memory-mapped files have led some to propose the use of a single virtual-address space, shared by all processes and processors. To simplify address-space management, some have claimed that a 64-bit address space is sufficiently large that there is no need to ever re-use addresses. Unfortunately, there has been no data to either support or refute these claims, or to aid in the design of appropriate address-space management policies. In this paper, we present the results of extensive kernel-level tracing of the workstations on our campus, and discuss the implications for …
