The Mobile Agent Rendezvous Problem in the Ring by Evangelos Kranakis,Danny Krizanc,Euripides Marcou Pdf
Mobile agent computing is being used in fields as diverse as artificial intelligence, computational economics and robotics. Agents' ability to adapt dynamically and execute asynchronously and autonomously brings potential advantages in terms of fault-tolerance, flexibility and simplicity. This monograph focuses on studying mobile agents as modelled in distributed systems research and in particular within the framework of research performed in the distributed algorithms community. It studies the fundamental question of how to achieve rendezvous, the gathering of two or more agents at the same node of a network. Like leader election, such an operation is a useful subroutine in more general computations that may require the agents to synchronize, share information, divide up chores, etc. The work provides an introduction to the algorithmic issues raised by the rendezvous problem in the distributed computing setting. For the most part our investigation concentrates on the simplest case of two agents attempting to rendezvous on a ring network. Other situations including multiple agents, faulty nodes and other topologies are also examined. An extensive bibliography provides many pointers to related work not covered in the text. The presentation has a distinctly algorithmic, rigorous, distributed computing flavor and most results should be easily accessible to advanced undergraduate and graduate students in computer science and mathematics departments. Table of Contents: Models for Mobile Agent Computing / Deterministic Rendezvous in a Ring / Multiple Agent Rendezvous in a Ring / Randomized Rendezvous in a Ring / Other Models / Other Topologies
Mobile Agents for Telecommunication Applications by Eric Horlait Pdf
Mobile agents refer to self-contained and identi?able computer programs that can move within the network and can act on behalf of the user or another entity. Most of the current research work on the mobile agent paradigm has two general goals: reduction of network traf?c and asynchronous interaction. These two goals stem directly from the desire to reduce information overload and to ef?ciently use network resources. There are certainly many motivations for the use of a mobile agent paradigm; h- ever, intelligent information retrieval, network and mobility management, and network services are currently the three most cited application targets for a mobile agent system. The aim of the workshop is to provide a unique opportunity for researchers, software and application developers, and computer network technologists to discuss new dev- opments in the mobile agent technology and applications. After last year’s very successful workshop in Ottawa, Canada (110 attendees), this year’s workshop will focus on mobile agent issues across the areas of network m- agement, mobile applications, nomadic computing, e-commerce, ad-hoc networks and applications, feature interactions, Internet applications, QoS management, policybased management, interactive multimedia, and computer–telephony integration.
Distributed Computing by Mobile Entities by Paola Flocchini,Giuseppe Prencipe,Nicola Santoro Pdf
Distributed Computing by Mobile Entities is concerned with the study of the computational and complexity issues arising in systems of decentralized computational entities operating in a spatial universe Encompassing and modeling a large variety of application environments and systems, from robotic swarms to networks of mobile sensors, from software mobile agents in communication networks to crawlers and viruses on the web, the theoretical research in this area intersects distributed computing with the fields of computational geometry (especially for continuous spaces), control theory, graph theory and combinatorics (especially for discrete spaces). The research focus is on determining what tasks can be performed by the entities, under what conditions, and at what cost. In particular, the central question is to determine what minimal hypotheses allow a given problem to be solved. This book is based on the lectures and tutorial presented at the research meeting on “Moving and Computing" (mac) held at La Maddalena Island in June 2017. Greatly expanded, revised and updated, each of the lectures forms an individual Chapter. Together, they provide a map of the current knowledge about the boundaries of distributed computing by mobile entities.
Mobility by Dejan S. Milojičić,Frederick Douglis,Richard Wheeler Pdf
The future of computing ever-increasingly lies in ever-increasing mobility in which computers continue their network operations while physically changing their location, and code moves from system to system performing its designated tasks throughout a network. This book brings together in one single resource the leading edge of research and practice in three areas of mobility: process migration, mobile computing, and mobile agents. Presented chronologically, the papers in this book--each written by leading experts in that particular area--track the development of critical technologies that have influenced mobility. Introductions by the editors and original afterwords by many of the papers' authors provide information on implementation and practical application, technological context, and updates on the most recent advances. The book highlights many common challenges and solutions inherent in various aspects of mobility: infrastructure, scalability, security, standards, robustness, naming and locating mobile entities, and more. Individual papers describe specific research and development in each of the three major areas, covering such topics as: An analysis of process migration from the earliest work to contemporary commercial systems Barriers to effective mobile connectivity, mobile IP, and ubiquitous computing Descriptions of various mobile agent systems, such as Telescript, Aglets, Agent TCL, and the mobile agent system standard (MASIF) This selection of influential papers illustrates the evolution of mobile technology as well as the state of the art of one of the most significant trends in computing. 0201379287B04062001
Distributed Network Systems by Weijia Jia,Wanlei Zhou Pdf
Both authors have taught the course of “Distributed Systems” for many years in the respective schools. During the teaching, we feel strongly that “Distributed systems” have evolved from traditional “LAN” based distributed systems towards “Internet based” systems. Although there exist many excellent textbooks on this topic, because of the fast development of distributed systems and network programming/protocols, we have difficulty in finding an appropriate textbook for the course of “distributed systems” with orientation to the requirement of the undergraduate level study for today’s distributed technology. Specifically, from - to-date concepts, algorithms, and models to implementations for both distributed system designs and application programming. Thus the philosophy behind this book is to integrate the concepts, algorithm designs and implementations of distributed systems based on network programming. After using several materials of other textbooks and research books, we found that many texts treat the distributed systems with separation of concepts, algorithm design and network programming and it is very difficult for students to map the concepts of distributed systems to the algorithm design, prototyping and implementations. This book intends to enable readers, especially postgraduates and senior undergraduate level, to study up-to-date concepts, algorithms and network programming skills for building modern distributed systems. It enables students not only to master the concepts of distributed network system but also to readily use the material introduced into implementation practices.
Security Modeling and Analysis of Mobile Agent Systems by Lu Ma,Jeffrey J.-P. Tsai Pdf
A mobile agent system could be attacked by malicious agents, platforms and third parties. Mobile agents simply offer greater opportunities for abuse and misuse, which broadens the scale of threats significantly. In addition, since mobile agents have some unique characteristics such as their mobility, security problems have become more complicated in these systems. These security problems have become a bottleneck in the development and maintenance of mobile agent systems, especially in security sensitive applications such as electronic commerce. This book introduces the concept and structure of mobile agent systems and discusses various attacks and countermeasures. The emphasis is on the formal modeling and analysis of secure mobile agent systems and their applications.
Mobile Processing in Distributed and Open Environments by Peter Sapaty Pdf
This book provides a comprehensive introduction to WAVE, a revolutionary technology that combines the power and flexibility of conventional sequential programming with the open, fully distributed architectures found in the most sophisticated CORBA-based systems. Developed by Peter Sapaty--a noted pioneer in the use of intelligent agents in open and distributed computing--more than a decade before Java, WAVE was designed specifically for use in large-scale distributed information systems. In Mobile Processing in Distributed and Open Environments, Sapaty provides a complete, hands-on tutorial in the WAVE programming language and its applications. Rather than simply describe the language and its features, he supplies a vast collection of WAVE algorithms, fully explained with working examples and application suggestions. He also supplies expert advice and guidance on designing, developing, and managing agent systems. Crucial topics covered include: * Managing information networks * Designing and managing communication networks * Performing distributed simulation and virtual reality with WAVE * Building and managing intelligent infrastructures for distributed systems * Using WAVE in conventional programming

New paradigms can popularize old technologies. A new \standalone" paradigm, the electronic desktop, popularized the personal computer. A new \connected" paradigm, the web browser, popularized the Internet. Another new paradigm, the mobile agent, may further popularize the Internet by giving people greater access to it with less eort. MobileAgentParadigm The mobile agent paradigm integrates a network of computers in a novel way designed to simplify the development of network applications. To an application developer the computers appear to form an electronic world of places occupied by agents. Each agent or place in the electronic world has the authority of an individual or an organization in the physical world. The authority can be established, for example, cryptographically. A mobile agent can travel from one place to another subject to the des- nation place’s approval. The source and destination places can be in the same computer or in di erent computers. In either case,the agentinitiates the trip by executing a \go" instruction which takes as an argument the name or address of the destination place. The next instruction in the agent’s program is executed in the destination place, rather than in the source place. Thus, in a sense, the mobile agent paradigm reduces networking to a program instruction. A mobile agent can interact programmatically with the places it visits and, if the other agents approve, with the other agents it encounters in those places.
Data Management for Mobile Computing by Evaggelia Pitoura,George Samaras Pdf
Earth date, August 11, 1997 "Beam me up Scottie!" "We cannot do it! This is not Star Trek's Enterprise. This is early years Earth." True, this is not yet the era of Star Trek, we cannot beam captain James T. Kirk or captain Jean Luc Pickard or an apple or anything else anywhere. What we can do though is beam information about Kirk or Pickard or an apple or an insurance agent. We can beam a record of a patient, the status of an engine, a weather report. We can beam this information anywhere, to mobile workers, to field engineers, to a track loading apples, to ships crossing the Oceans, to web surfers. We have reached a point where the promise of information access anywhere and anytime is close to realization. The enabling technology, wireless networks, exists; what remains to be achieved is providing the infrastructure and the software to support the promise. Universal access and management of information has been one of the driving forces in the evolution of computer technology. Central computing gave the ability to perform large and complex computations and advanced information manipulation. Advances in networking connected computers together and led to distributed computing. Web technology and the Internet went even further to provide hyper-linked information access and global computing. However, restricting access stations to physical location limits the boundary of the vision.
Mobile Computing by Tomasz Imielinski,Henry F. Korth Pdf
The rapid development of wireless digital communication technology has cre ated capabilities that software systems are only beginning to exploit. The falling cost of both communication and of mobile computing devices (laptop computers, hand-held computers, etc. ) is making wireless computing affordable not only to business users but also to consumers. Mobile computing is not a "scaled-down" version of the established and we- studied field of distributed computing. The nature of wireless communication media and the mobility of computers combine to create fundamentally new problems in networking, operating systems, and information systems. Further more, many of the applications envisioned for mobile computing place novel demands on software systems. Although mobile computing is still in its infancy, some basic concepts have been identified and several seminal experimental systems developed. This book includes a set of contributed papers that describe these concepts and sys tems. Other papers describe applications that are currently being deployed and tested. The first chapter offers an introduction to the field of mobile computing, a survey of technical issues, and a summary of the papers that comprise sub sequent chapters. We have chosen to reprint several key papers that appeared previously in conference proceedings. Many of the papers in this book are be ing published here for the first time. Of these new papers, some are expanded versions of papers first presented at the NSF-sponsored Mobidata Workshop on Mobile and Wireless Information Systems, held at Rutgers University on Oct 31 and Nov 1, 1994.

Material-Integrated Intelligent Systems by Stefan Bosse,Dirk Lehmhus,Walter Lang,Matthias Busse Pdf
Combining different perspectives from materials science, engineering, and computer science, this reference provides a unified view of the various aspects necessary for the successful realization of intelligent systems. The editors and authors are from academia and research institutions with close ties to industry, and are thus able to offer first-hand information here. They adopt a unique, three-tiered approach such that readers can gain basic, intermediate, and advanced topical knowledge. The technology section of the book is divided into chapters covering the basics of sensor integration in materials, the challenges associated with this approach, data processing, evaluation, and validation, as well as methods for achieving an autonomous energy supply. The applications part then goes on to showcase typical scenarios where material-integrated intelligent systems are already in use, such as for structural health monitoring and smart textiles.
