This book was released on 2011 with total page 216 pages. Available in PDF, EPUB and Kindle. Book excerpt: This work proposes a client-based cache consistency scheme that is implemented on top of a previously proposed architecture for caching data items in MANETs that caches submitted queries in special nodes, called query directories (QDs), and uses them to locate the data (responses) that are stored in the nodes that requested them, called caching nodes (CNs). In this work, we introduce a totally client-based scheme that is termed DCIM which works by having the QD nodes monitor the TTL values of the cached data items and estimate update patterns on the server to adapt the TTL values accordingly. The QDs also monitor the request rates for data items and decide accordingly which items to prefetch. DCIM is analyzed to assess the delay and bandwidth gains (or costs) when compared to polling every time, and was also simulated along with two other client based schemes to assess its performance experimentally. The consistency ratio, delay, and overhead traffic are reported versus several variables, and DCIM shows to be superior when compared to existing systems.--Furthermore, DCIM is extended to handle multiple replicas inside the MANET. For this purpose, it utilizes a push based approach to propagate updates to replicas inside the network. The result is a hybrid approach that utilizes the benefits of pull approaches for client server communication, and the benefits of push approaches inside the network between the replicas. This method is analyzed mathematically, and the optimal number of replicas is obtained. It is concluded that full replication at the QDs and partial replication at the CNs is optimal. This finding is used to design the replica allocation scheme using a cost minimization model that enhances the operation of DCIM in terms of access delay and data hit rate. At the end, we provide a security analysis for the operations of the proposed system.

Download or read book Routing Flow and Capacity Design in Communication and Computer Networks written by Michal Pioro and published by Elsevier. This book was released on 2004-07-21 with total page 795 pages. Available in PDF, EPUB and Kindle. Book excerpt: In network design, the gap between theory and practice is woefully broad. This book narrows it, comprehensively and critically examining current network design models and methods. You will learn where mathematical modeling and algorithmic optimization have been under-utilized. At the opposite extreme, you will learn where they tend to fail to contribute to the twin goals of network efficiency and cost-savings. Most of all, you will learn precisely how to tailor theoretical models to make them as useful as possible in practice.Throughout, the authors focus on the traffic demands encountered in the real world of network design. Their generic approach, however, allows problem formulations and solutions to be applied across the board to virtually any type of backbone communication or computer network. For beginners, this book is an excellent introduction. For seasoned professionals, it provides immediate solutions and a strong foundation for further advances in the use of mathematical modeling for network design. Written by leading researchers with a combined 40 years of industrial and academic network design experience. Considers the development of design models for different technologies, including TCP/IP, IDN, MPLS, ATM, SONET/SDH, and WDM. Discusses recent topics such as shortest path routing and fair bandwidth assignment in IP/MPLS networks. Addresses proper multi-layer modeling across network layers using different technologies—for example, IP over ATM over SONET, IP over WDM, and IDN over SONET. Covers restoration-oriented design methods that allow recovery from failures of large-capacity transport links and transit nodes. Presents, at the end of each chapter, exercises useful to both students and practitioners.

Download or read book Recent Advances in Cryptography and Network Security written by Pinaki Mitra and published by BoD – Books on Demand. This book was released on 2018-10-31 with total page 70 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the field of computers and with the advent of the internet, the topic of secure communication has gained significant importance. The theory of cryptography and coding theory has evolved to handle many such problems. The emphases of these topics are both on secure communication that uses encryption and decryption schemes as well as on user authentication for the purpose of non-repudiation. Subsequently, the topics of distributed and cloud computing have emerged. Existing results related to cryptography and network security had to be tuned to adapt to these new technologies. With the more recent advancement of mobile technologies and IOT (internet of things), these algorithms had to take into consideration the limited resources such as battery power, storage and processor capabilities. This has led to the development of lightweight cryptography for resource constrained devices. The topic of network security also had to face many challenges owing to variable interconnection topology instead of a fixed interconnection topology. For this reason, the system is susceptible to various attacks from eavesdroppers. This book addresses these issues that arise in present day computing environments and helps the reader to overcome these security threats.

Download or read book Internet of Things and Inter cooperative Computational Technologies for Collective Intelligence written by Nik Bessis and published by Springer. This book was released on 2012-12-14 with total page 476 pages. Available in PDF, EPUB and Kindle. Book excerpt: Over the past two decades, we have witnessed unprecedented innovations in the development of miniaturized electromechanical devices and low-power wireless communication making practical the embedding of networked computational devices into a rapidly widening range of material entities. This trend has enabled the coupling of physical objects and digital information into cyber-physical systems and it is widely expected to revolutionize the way resource computational consumption and provision will occur. Specifically, one of the core ingredients of this vision, the so-called Internet of Things (IoT), demands the provision of networked services to support interaction between conventional IT systems with both physical and artificial objects. In this way, IoT is seen as a combination of several emerging technologies, which enables the transformation of everyday objects into smart objects. It is also perceived as a paradigm that connects real world with digital world. The focus of this book is exactly on the novel collective and computational intelligence technologies that will be required to achieve this goal. While, one of the aims of this book is to discuss the progress made, it also prompts future directions on the utilization of inter-operable and cooperative next generation computational technologies, which supports the IoT approach, that being an advanced functioning towards an integrated collective intelligence approach for the benefit of various organizational settings.

Download or read book Interconnecting Smart Objects with IP written by Jean-Philippe Vasseur and published by Morgan Kaufmann. This book was released on 2010-07-06 with total page 432 pages. Available in PDF, EPUB and Kindle. Book excerpt: Interconnecting Smart Objects with IP: The Next Internet explains why the Internet Protocol (IP) has become the protocol of choice for smart object networks. IP has successfully demonstrated the ability to interconnect billions of digital systems on the global Internet and in private IP networks. Once smart objects can be easily interconnected, a whole new class of smart object systems can begin to evolve. The book discusses how IP-based smart object networks are being designed and deployed. The book is organized into three parts. Part 1 demonstrates why the IP architecture is well suited to smart object networks, in contrast to non-IP based sensor network or other proprietary systems that interconnect to IP networks (e.g. the public Internet of private IP networks) via hard-to-manage and expensive multi-protocol translation gateways that scale poorly. Part 2 examines protocols and algorithms, including smart objects and the low power link layers technologies used in these networks. Part 3 describes the following smart object network applications: smart grid, industrial automation, smart cities and urban networks, home automation, building automation, structural health monitoring, and container tracking. Shows in detail how connecting smart objects impacts our lives with practical implementation examples and case studies Provides an in depth understanding of the technological and architectural aspects underlying smart objects technology Offers an in-depth examination of relevant IP protocols to build large scale smart object networks in support of a myriad of new services
