This book was released on 2023 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: The research field in distributed systems has witnessed a recent growing interest in wireless mobile distributed computing, i.e. distributed algorithms deployed in dynamic networks. Such systems introduce new challenges due to their time-varying topologies, which hinder the performance and safety guarantees of algorithms that are fundamental building blocks of more complex distributed algorithms. The main focus of this work is to establish different ways to study such systems via emulation and simulation and to propose some techniques to deploy applications in dynamic networks. We evaluated different data flow paradigms, such as many-to-many distributed storage, one-many computational offloading, and many-to-many decentralized swarm control and data load-balancing.We adopted the quantitative approach as a cornerstone methodology, using simulation and emulation to collect data for analysis. Even though there are many discrete simulators in the state-of-the-art, there was a gap for emulation tools applied to mobile ad hoc computing. Some important features were missing, such as a full-scale emulated deployment environment where prototypes coexist with off-the-shelf applications and more options for mobility control. This work proposes MACE, a framework that enables the emulation of mobile distributed applications in a virtual environment so that the scenarios and topologies composed by mobile wireless nodes can be easily modified. Since emulation requires that the tests run in wall time, the need for a fast simulator arose. Therefore, we designed, implemented and validated a fluid model that simulates traffic flow in mobile ad hoc networks. With this model, we finally implemented a simulation tool that enables fast algorithm and parameter analysis and can potentially be embedded in constrained nodes for in-flight mission re-evaluation. The fluid model can scale to large topologies with hundreds of nodes and could complete experiments running stress workloads with simulation time shorter than the simulation time horizon. It can also be configured with bounded and unbounded network queues, use mixed mobility models and control laws, and model different applications running in the application layer mixed with synthetic traffic injection. By studying different control laws, we can reduce the probability of enduring network partitions and enhance the traffic balance to reduce the formation of bottlenecks that hinder the application's performance.Our work also encompassed the proposal of some applications related to the domain of UTM, such as optimized edge-assisted offloading algorithms for swarms of UAVs that can be potentially used for UTM Distributed Detect and Avoid systems. Moreover, we also propose a distributed position tracking data layer for very low-level airspace using State Machine Replication and could achieve low end-to-end latencies even with a high number of replicas.

Book Synopsis Parallel and Distributed Cyber-physical System Simulation by : Dylan Conrad Pfeifer
Download or read book Parallel and Distributed Cyber-physical System Simulation written by Dylan Conrad Pfeifer and published by . This book was released on 2013 with total page 320 pages. Available in PDF, EPUB and Kindle. Book excerpt: The traditions of real-time and embedded system engineering have evolved into a new field of cyber-physical systems (CPSs). The increase in complexity of CPS components and the multi-domain engineering composition of CPSs challenge the current best practices in design and simulation. To address the challenges of CPS simulation, this work introduces a simulator coordination method drawing from strengths of the field of parallel and distributed simulation (PADS), yet offering benefits aimed towards the challenges of coordinating CPS engineering design simulators. The method offers the novel concept of Interpolated Event data types applied to Kahn Process Networks in order to provide simulator coordination. This can enable conservative and optimistic coordination of multiple heterogeneous and homogeneous simulators, but provide important benefits for CPS simulation, such as the opportunity to reduce functional requirements for simulator interfacing compared to existing solutions. The method is analyzed in theoretical properties and instantiated in software tools SimConnect and SimTalk. Finally, an experimental study applies the method and tools to accelerate Spice circuit simulation with tradeoffs in speed versus accuracy, and demonstrates the coordination of three heterogeneous simulators for a CPS simulation with increasing component model refinement and realism.
Book Synopsis Distributed Network Systems by : Weijia Jia
Download or read book Distributed Network Systems written by Weijia Jia and published by Springer Science & Business Media. This book was released on 2006-06-14 with total page 531 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Book Synopsis Modeling and Simulation in HPC and Cloud Systems by : Joanna Kołodziej
Download or read book Modeling and Simulation in HPC and Cloud Systems written by Joanna Kołodziej and published by Springer. This book was released on 2019-06-07 with total page 155 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book consists of eight chapters, five of which provide a summary of the tutorials and workshops organised as part of the cHiPSet Summer School: High-Performance Modelling and Simulation for Big Data Applications Cost Action on “New Trends in Modelling and Simulation in HPC Systems,” which was held in Bucharest (Romania) on September 21–23, 2016. As such it offers a solid foundation for the development of new-generation data-intensive intelligent systems. Modelling and simulation (MS) in the big data era is widely considered the essential tool in science and engineering to substantiate the prediction and analysis of complex systems and natural phenomena. MS offers suitable abstractions to manage the complexity of analysing big data in various scientific and engineering domains. Unfortunately, big data problems are not always easily amenable to efficient MS over HPC (high performance computing). Further, MS communities may lack the detailed expertise required to exploit the full potential of HPC solutions, and HPC architects may not be fully aware of specific MS requirements. The main goal of the Summer School was to improve the participants’ practical skills and knowledge of the novel HPC-driven models and technologies for big data applications. The trainers, who are also the authors of this book, explained how to design, construct, and utilise the complex MS tools that capture many of the HPC modelling needs, from scalability to fault tolerance and beyond. In the final three chapters, the book presents the first outcomes of the school: new ideas and novel results of the research on security aspects in clouds, first prototypes of the complex virtual models of data in big data streams and a data-intensive computing framework for opportunistic networks. It is a valuable reference resource for those wanting to start working in HPC and big data systems, as well as for advanced researchers and practitioners.

Download or read book Distributed Optimization for Smart Cyber-Physical Networks written by Giuseppe Notarstefano and published by . This book was released on 2019-12-11 with total page 148 pages. Available in PDF, EPUB and Kindle. Book excerpt: In an increasingly connected world, the term cyber-physical networks has been coined to refer to the communication among devices that is turning smart devices into smart (cooperating) systems. The distinctive feature of such systems is that significant advantage can be obtained if its interconnected, complex nature is exploited. Several challenges arising in cyber-physical networks can be stated as optimization problems. Examples are estimation, decision, learning and control applications. In cyber-physical networks, the goal is to design algorithms, based on the exchange of information among the processors, that take advantage of the aggregated computational power. Distributed Optimization for Smart Cyber-Physical Networks provides a comprehensive overview of the most common approaches used to design distributed optimization algorithms, together with the theoretical analysis of the main schemes in their basic version. It identifies and formalizes classes of problem set-ups that arise in motivating application scenarios. For each set-up, in order to give the main tools for analysis, tailored distributed algorithms in simplified cases are reviewed. Extensions and generalizations of the basic schemes are also discussed at the end of each chapter. Distributed Optimization for Smart Cyber-Physical Networks provides the reader with an accessible overview of the current research and gives important pointers towards new developments. It is an excellent starting point for research and students unfamiliar with the topic.

Book Synopsis Model Based Assertions by : Garrett Warne Idler
Download or read book Model Based Assertions written by Garrett Warne Idler and published by . This book was released on 2015 with total page 138 pages. Available in PDF, EPUB and Kindle. Book excerpt: Cyber-physical systems (CPS) are a class of systems with electronic and mechanical components that use computer control, information networking, and physical behavior to accomplish designated tasks. CPS have become ubiquitous in society and are taking roles with important safety and reliability concerns. To address these concerns, many types of tools and design methodologies are being developed specifically for cyber-physical systems. This thesis introduces the concept of model based assertions, a programming construct for capturing the physical behavior of the system in the cyber side of the system by using numerical models to represent the physical system characteristics of interest. The model based assertions are proposed to be used for the verification and validation of CPS software. In order to set up discussion of model based assertions, several definitions of cyber-physical systems from researchers in the area are presented and discussed along with a brief overview of tools for cyber-physical system design, modeling, and evaluation. A robotic ground vehicle is adopted as a cyber-physical system test platform, as it displays the critical characteristics of a CPS. In order to formulate example model based assertions, three different types of numerical models of the robotic vehicle are introduced and discussed with bond graphs used as an approach for deriving state equations which describe the physical system dynamics. After introducing the numerical models, three examples of using model based assertions for tests with the robotic vehicle platform are presented. In the examples, model based assertions are used to verify expected motion of the vehicle and predict when the vehicle is going to slip during advanced maneuvers, both using preprocessed model simulations and real-time slip prediction during program execution. The thesis concludes with discussing possible use cases of model based assertions and situations where the assertions could present useful information to a cyber-physical system designer. Finally, future work related to developing model based assertions for additional applications is discussed.
Book Synopsis A SIMULATION PLATFORM FOR EXPERIMENTATION AND EVALUATION OF DISTRIBUTED-COMPUTING SYSTEMS. by :
Download or read book A SIMULATION PLATFORM FOR EXPERIMENTATION AND EVALUATION OF DISTRIBUTED-COMPUTING SYSTEMS. written by and published by . This book was released on 2005 with total page 382 pages. Available in PDF, EPUB and Kindle. Book excerpt: Distributed simulations have been widely applied as the method to study complex systems which are analytically intractable and numerically prohibitive to evaluate. However it is not a trivia task to develop distributed simulations. Besides distributed simulations may introduce difficulties for analysis due to decentralized, heterogeneous data sources. It is important to integrate these data sources seamlessly for analysis. In applications for system design, it is required to explore the alternatives of hardware components, algorithms, and simulation models. How to enable these operations conveniently is critical for the distributed system as well. All these challenges raise the need of a workbench that facilitates rapid composition, evaluation, modification and validation of components in a distributed system. This dissertation proposes a platform for these challenges, which we refer to the SPEED-CS platform. The architecture of the platform consists of multiple layers that include network layer, component management layer, components layer, and modeling layer. It is a multi-agent system (MAS), containing static agents and mobile agents. The mobile agent is referred as the Data Exchange Agent, which is able to visit sub-simulations and has the intelligence to find the useful data for output analysis. Experiments show that the MAS requires much less network bandwidth than the"centralized"system does, in which simulations report data to output analyst. The application of the SPEED-CS platform is extended to handle systems with dynamic data sources. We demonstrate that the platform can be used for parallel reality applications where simulation parameters can be updated according to real-time sensor information. Data exchange agents are involved to manage the collection, dissemination, and analysis of data from dynamic data sources including simulations and/or physical systems. The SPEED-CS platform is also implemented to integrate simulations and optimizations. The system is able to provide services to facilitate distributed computing, event services, naming services, and component management. One of the important features is that the component sets can be updated and enlarged with different models adding in. This feature enables the platform to work as a testbed to explore alternatives of system designs. Finally we conclude this dissertation with several future research topics.
