Book Description
Abstract: "We study communication primitives for interaction between mobile agents. They can be classified into two groups. At a low level there are location dependent primitives that require a programmer to know the current site of a mobile agent in order to communicate with it. At a high level there are location independent primitives that allow communication with a mobile agent irrespective of its current site and of any migrations. Implementation of these requires delicate distributed infrastructure. We propose a simple calculus of agents that allows implementations of such distributed infrastructure algorithms to be expressed as encodings, or compilations of the whole calculus into the fragment with only location dependent communication. These encodings give executable descriptions of the algorithms, providing a clean implementation strategy for prototype languages. The calculus is equipped with a precise semantics, providing a solid basis for understanding the algorithms and for reasoning about their correctness and robustness. Two sample infrastructure algorithms are presented as encodings."

Book Description
Mobile agents are intelligent agents with advanced mobility capabilities. A mobile agent must be provided with the so called strong mobility, a feature which allows it to carry its status with it and accomplish its mission by migrating from site to site in the Internet. A mobile agent can complete in a site what it started in another site.Starting from the mobile agent concept, this book provides the reader with a suitably detailed discussion on mobile agent principles of operation, as for instance, migration, communication, co-ordination, interoperability, fault tolerance and security. As an example of mobile agents application fields, this book discusses how they can be effective in implementing data mining and information retrieval systems.

Book Description
Recent years have witnessed the appearance of new paradigms for designing distributed applications where the application components can be relocated - namically across the hosts of the network. This form of code mobility lays the foundation for a new generation of technologies, architectures, models, and - plications in which the location at which the code is executed comes under the control of the designer, rather than simply being a con?guration accident. Among the various ?avors of mobile code, the mobile agent paradigm has become particularly popular. Mobile agents are programs able to determine - tonomously their own migration to a di?erent host, and still retain their code and state (or at least a portion thereof). Thus, distributed computations do not necessarily unfold as a sequence of requests and replies between clients and - mote servers, rather they encompass one or more visits of one or more mobile agents to the nodes involved. Mobile code and mobile agents hold the potential to shape the next gene- tion of technologies and models for distributed computation. The ?rst steps of this process are already evident today: Web applets provide a case for the least sophisticated form of mobile code, Java-based distributed middleware makes - creasing use of mobile code, and the ?rst commercial applications using mobile agents are starting to appear.

Book Description
This book constitutes the thoroughly refereed post-proceedings of the First International Workshop on Formal Approaches to Agent-Based Systems, FAABS 2000, held in Greenbelt, MD, USA, in April 2000. The 22 revised full papers presented together with 13 posters and two panel discussion reports were carefully reviewed and improved for inclusion in the book. The papers are organized in topical sections on verifying agents' mental states, synthesizing agents initially, frameworks and formalizations, modeling and execution, inter-agent communication, and adaptive agents.

Book Description
Distributed applications are a necessity in most central application sectors of the contemporary information society, including e-commerce, e-banking, e-learning, e-health, telecommunication and transportation. This results from a tremendous growth of the role that the Internet plays in business, administration and our everyday activities. This trend is going to be even further expanded in the context of advances in broadband wireless communication. New Developments in Distributed Applications and Interoperable Systems focuses on the techniques available or under development with the goal to ease the burden of constructing reliable and maintainable interoperable information systems providing services in the global communicating environment. The topics covered in this book include: Context-aware applications; Integration and interoperability of distributed systems; Software architectures and services for open distributed systems; Management, security and quality of service issues in distributed systems; Software agents and mobility; Internet and other related problem areas. The book contains the proceedings of the Third International Working Conference on Distributed Applications and Interoperable Systems (DAIS'2001), which was held in September 2001 in Kraków, Poland, and sponsored by the International Federation on Information Processing (IFIP). The conference program presents the state of the art in research concerning distributed and interoperable systems. This is a topical research area where much activity is currently in progress. Interesting new aspects and innovative contributions are still arising regularly. The DAIS series of conferences is one of the main international forums where these important findings are reported.

Book Description
This book is a collection of articles about the influence that the recent greater scope and availability of wide area networks is having on the semantics, design, and implementa tion of programming languages. The Internet has long provided a global computing in frastructure but, for most of its history, there has not been much interest in programming languages tailored specifically to that infrastructure. More recently, the Web has pro duced a widespread interest in global resources and, as a consequence, in global pro grammability. It is now commonplace to discuss how programs can be made to run effectively and securely over the Internet. The Internet has already revolutionized the distribution and access of information, and is in the process of transforming commerce and other areas of fundamental importance. In the field of programming languages, the Internet is having a deep revitalizing effect, by challenging many fundamental assumptions and requiring the development of new concepts, programming constructs, implementation techniques, and applications. This book is a snapshot of current research in this active area. The articles in this book were presented at the Workshop on Internet Programming Lan guages, which was held on May 13, 1998 at Loyola University, Chicago, USA. The pa pers submitted to the workshop were screened by the editors. After the workshop, the presented papers were refereed by an external reviewer and one of the editors, resulting in the current selection.
