Well adapted to the loosely coupled nature of distributed interaction in large-scale applications, the publish/subscribe communication paradigm has recently received increasing attention. With systems based on the publish/subscribe interaction scheme, subscribers register their interest in an event, or a pattern of events, and are subsequently asynchronously notified of events generated by publishers. Many variants of the paradigm have recently been proposed, each variant being specifically adapted to some given application or network model. This paper factors out the common denominator underlying these variants: full decoupling of the communicating entities in time, space, and synchronization. We use these three decoupling dimensions to better identify commonalities and divergences with traditional interaction paradigms. The many variations on the theme of publish/subscribe are classified and synthesized. In particular, their respective benefits and shortcomings are discussed both in terms of interfaces and implementations.

The many faces of publish/subscribe

From the Publisher:
An agent is an entity with domain knowledge, goals and actions. Multi-agent systems are a set of agents which
interact in a common environment. Multi-agent systems deal with the construction of complex systems involving multiple agents and their coordination. A multi-agent system (MAS) is a distributed computing system with
autonomous interacting intelligent agents that coordinate their actions so as to achieve its goal(s) jointly or competitively.

Introduction to Multiagent Systems

A type system is a syntactic method for automatically checking the absence of certain erroneous behaviors by classifying program phrases according to the kinds of values they compute. The study of type systems -- and of programming languages from a type-theoretic perspective -- has important applications in software engineering, language design, high-performance compilers, and security.This text provides a comprehensive introduction both to type systems in computer science and to the basic theory of programming languages. The approach is pragmatic and operational; each new concept is motivated by programming examples and the more theoretical sections are driven by the needs of implementations. Each chapter is accompanied by numerous exercises and solutions, as well as a running implementation, available via the Web. Dependencies between chapters are explicitly identified, allowing readers to choose a variety of paths through the material.The core topics include the untyped lambda-calculus, simple type systems, type reconstruction, universal and existential polymorphism, subtyping, bounded quantification, recursive types, kinds, and type operators. Extended case studies develop a variety of approaches to modeling the features of object-oriented languages.

Types and Programming Languages

What can computer simulation contribute to the social sciences? Which of the many approaches to simulation would be best for my social science project? How do I design, carry out and analyse the results from a computer simulation? This is a practical textbook on the techniques of building computer simulations to assist understanding of social and economic issues and problems. Interest in social simulation has been growing rapidly worldwide as a result of increasingly powerful hardware and software and also a rising interest in the application of ideas of complexity, evolution, adaptation and chaos in the social sciences. This authoritative book details all the common approaches to social simulation, to provide social scientists with an appreciation of the literature and allow those with some programming skills to create their own simulations.New for this edition is a chapter on how to use simulation as a tool. A new chapter on multi-agent systems has also been added to support the fact that multi-agent modelling has become the preferred approach to simulation. Social scientists in a wide range of fields will find this book an essential tool for research, particularly in sociology, economics, anthropology, geography, organizational theory, political science, social policy, cognitive psychology and cognitive science. It will also appeal to computer scientists interested in distributed artificial intelligence, multi-agent systems and agent technologies.

Simulation for the Social Scientist

Social science research contains a wealth of knowledge for people seeking to understand collaboration processes. The authors argue that public managers should look inside the “black box” of collaboration processes. Inside, they will find a complex construct of five variable dimensions: governance, administration, organizational autonomy, mutuality, and norms. Public managers must know these five dimensions and manage them intentionally in order to collaborate effectively.

The Java Programming Language

From the Book:
PREFACE: 
Over the next decade the computing landscape will change dramatically as devices become ubiquitous, network-connected, and ready to communicate. As the landscape changes, the way in which we design and build software will change as well: The distributed application (one that involves multiple processes and devices) will become the natural way we build systems, while the standalone desktop application will become nearly extinct. 

Designing distributed software is remarkably hard, however. The fundamental characteristics of a networked environment (such as heterogeneity, partial failure, and latency) and the difficulty of "gluing together" multiple, independent processes into a robust, scalable application present the programmer with many challenges that don't arise when designing and building desktop applications. 

JavaSpaces(TM) technology is a simple, expressive, and powerful tool that eases the burden of creating distributed applications. Processes are loosely coupledcommunicating and synchronizing their activities using a persistent object store called a space, rather than through direct communication. This method of coordinating distributed processes leads to systems that are flexible, scalable, and reliable. While simple, the space-based model is powerful enough to implement advanced distributed applicationsfrom e-commerce systems to groupware to heavy-duty parallel computations. Space-based programming also leverages the Jini(TM) technology's leasing, distributed event, and transaction features, making it suitable for building robust, commercial-quality distributed systems. 

This book teaches you how touseJavaSpaces technology to design and build distributed applications. It is intended for computer professionals, students, and Java enthusiastsanyone who wants experience building networked applications. Through experimentation with the code examples, you'll develop a repertoire of useful techniques and patterns for creating space-based systems. We assume that you already have some programming experience and basic working knowledge of Java programming language fundamentals, but this book doesn't require any specific knowledge of network programming. 

JavaSpaces technology is new, and writing a book before the technology is in widespread use presents a unique challenge. We've approached the project from complementary perspectives. Two of the authors, Eric Freeman and Susanne Hupfer, spent much of the past decade designing and building space-based systems as part of the Linda research group at Yale University and used the JavaSpaces technology during the two years of its development. The third, Ken Arnold, was in charge of the JavaSpaces project at Sun Microsystems, working with a team of engineers to design and build the technology this book is all about. 

In this book, we present the foundations of programming with JavaSpaces technology, and a set of common patterns and frameworks for approaching space-based programs. As the technology becomes more widely used, the JavaSpace programming community will discover new ways of using it. We would like future editions of this book to incorporate these new patterns, and we invite you to send comments, suggestions, and ideas to javaspaces@awl.com and to make use of the book's web site at ...
