In this monograph, Joachim Baumann provides in-depth coverage of essential research issues; namely, mechanisms for locating and terminating mobile agents and for orphan detection in a mobile agent system. The reader will gain insights into the design and implementation of three control mechanisms for use in mobile agent systems: the energy concept, the path concept, and the shadow concept. The author examines these mechanisms and offers a solid argument as to why they would be better choices over existing mechanisms with respect to message complexity, migration delay, and availability. All in all, this book is an outstanding contribution to advancing the science of mobile agents and it will help the community better understand how to tame mobile agents.

Abstract: "Cooperating merchants establish a distributed marketplace under the auspices of an independent market authority. Each merchant's server is equipped with a trusted device, a smart card for example, provided by the market authority. The market authority plays the role of a trusted third party for the customer as well as for the merchants. This paper describes protocols that prevent the malicious alteration of the data collected by visiting mobile agents roaming through the marketplace without being detectable by subsequent servers or by the owner of the agent upon its return. Another protocol makes the trusted device a secure execution platform for routines provided by the agent owner."

A atudy of mobile agents and security. The mobile agents paradigm integrates a network of computers and reduces networking to program construction. A mobile agent can travel from one place to another, and, subject to the destination's approval, interact programmatically with the place it visits.

Abstract: "Fault-tolerance is fundamental to the further development of mobile agent applications. In the context of mobile agents, fault-tolerance prevents a partial or complete loss of the agent, i.e., ensures that the agent arrives at its destination. Simple approaches such as checkpointing are prone to blocking. Replication can in principle improve solutions based on checkpointing. However, existing solutions in this context either assume a perfect failure detection mechanism (which is not realistic in an environment such as the Internet), or rely on complex solutions based on leader election and distributed transactions, where only a subset of solutions prevents blocking. This paper proposes a novel approach to fault-tolerant mobile agent execution, which is based on modeling agent execution as a sequence of agreement problems. Each agreement problem is one instance of the well understood consensus problem. Our solution does not require a perfect failure detection mechanism, while preventing blocking and ensuring that the agent is executed exactly once."

Mobile agents are software nomads that act as your personal representative, working autonomously through networks. They are able to visit network nodes directly using available computing power and are not limited by platform. This emerging field is now poised to become a cornerstone for new Web-based ubiquitous computing environments. Mobile Agents provides a practical introduction to mobile agent technology and surveys the state of the art in mobile agent research. Students and researchers can use the book as an introduction to the concepts and possibilities of this field and as an overview of ongoing research. Developers can use it to identify the capabilities of the technology to decide if mobile agents are the right solution for them. Practioners can also gain hands-on experience in programming mobile agents through exploration of the source code for a complete mobile agent environment available through the companion website.

A sequel to Mobile Processing in Distributed and Open Environments, this title introduces an extended, universal WAVE-WP model for distributed processing and control in dynamic and open worlds of any natures. The new control theory and technology introduced in the book can be widely used for the design and implementation of many distributed control systems, such as intelligent network management for the Internet, mobile cooperative robots, Rapid Reaction forces, future Combat Systems, robotics and AI, NMD, space research on other planets, and other applications. This title: - Demonstrates a much simpler and more efficient application programming - Cultivates a new kind of thinking about how large dynamic systems should be designed, organized, tasked, simulated, and controlled - Introduces an extended, universal WAVE-WP model for distributed processing - Compares the universal WAVE-WP model to other existing systems used in intelligent networking.
