Download or read book Risk Propagation Assessment for Network Security written by Mohamed Slim Ben Mahmoud and published by John Wiley & Sons. This book was released on 2013-04-08 with total page 83 pages. Available in PDF, EPUB and Kindle. Book excerpt: The focus of this book is risk assessment methodologies for network architecture design. The main goal is to present and illustrate an innovative risk propagation-based quantitative assessment tool. This original approach aims to help network designers and security administrators to design and build more robust and secure network topologies. As an implementation case study, the authors consider an aeronautical network based on AeroMACS (Aeronautical Mobile Airport Communications System) technology. AeroMACS has been identified as the wireless access network for airport surface communications that will soon be deployed in European and American airports mainly for communications between aircraft and airlines. It is based on the IEEE 802.16-2009 standard, also known as WiMAX. The book begins with an introduction to the information system security risk management process, before moving on to present the different risk management methodologies that can be currently used (quantitative and qualitative). In the third part of the book, the authors’ original quantitative network risk assessment model based on risk propagation is introduced. Finally, a network case study of the future airport AeroMACS system is presented. This example illustrates how the authors’ quantitative risk assessment proposal can provide help to network security designers for the decision-making process and how the security of the entire network may thus be improved.

Download or read book Software Networks written by Guy Pujolle and published by John Wiley & Sons. This book was released on 2015-08-31 with total page 260 pages. Available in PDF, EPUB and Kindle. Book excerpt: The goal of this book is to describe new concepts for Internet next generation. This architecture is based on virtual networking using Cloud and datacenters facilities. Main problems concern 1) the placement of virtual resources for opening a new network on the fly, and 2) the urbanisation of virtual resource implemented on physical network equipment. This architecture deals with mechanisms capable of controlling automatically the placement of all virtual resources within the physical network. In this book, we describe how to create and delete virtual networks on the fly. Indeed, the system is able to create any new network with any kind of resource (e.g., virtual switch, virtual routers, virtual LSRs, virtual optical path, virtual firewall, virtual SIP-based servers, virtual devices, virtual servers, virtual access points, and so on). We will show how this architecture is compatible with new advances in SDN (Software Defined Networking), new high-speed transport protocol like TRILL (Transparent Interconnection of Lots of Links) and LISP (Locator/Identifier Separation Protocol), NGN, IMS, Wi-Fi new generation, and 4G/5G networks. Finally, we introduce the Cloud of security and the virtualisation of secure elements (smartcard) that should definitely transform how to secure the Internet.

Download or read book Deterministic Network Calculus written by Anne Bouillard and published by John Wiley & Sons. This book was released on 2018-10-22 with total page 350 pages. Available in PDF, EPUB and Kindle. Book excerpt: Deterministic network calculus is a theory based on the (min,plus) algebra. Its aim is to compute worst-case performance bounds in communication networks. Our goal is to provide a comprehensive view of this theory and its recent advances, from its theoretical foundations to its implementations. The book is divided into three parts. The first part focuses on the (min,plus) framework and its algorithmic aspects. The second part defines the network calculus model and analyzes one server in isolation. Different service and scheduling policies are discussed, particularly when data is packetized. The third part is about network analyses. Pay burst only once and pay multiplexing only once phenomena are exhibited, and different analyses are proposed and compared. This includes the linear programming approaches that compute tight performance bounds. Finally, some partial results on the stability are detailed.

Download or read book Wi Fi Integration to the 4G Mobile Network written by André Pérez and published by John Wiley & Sons. This book was released on 2018-03-15 with total page 288 pages. Available in PDF, EPUB and Kindle. Book excerpt: The adoption of smartphones has had as a corollary the use of services that require streaming, such as video streaming, which is a constraint for the 4G mobile network. The integration of the network of Wi-Fi hotspots deployed by the operators adds capacity to the 4G mobile network. The use of Wi-Fi technology in carrier networks is the result of developments coordinated by the IEEE, WFA and WBA standardization bodies. For its part, the 3GPP standardization body has been working to integrate Wi-Fi technology into the 4G mobile network. The first part of this book presents the characteristics of the Wi-Fi radio interface. The different IEEE 802.11b / g / n / ac physical layers characterize the implementation in the 2.4 GHz ISM frequency bands and U- NII at 5 GHz. The MAC layer defines a number of media access procedures such as scanning, associating, or transferring data. The second part of this book deals with the architecture of the 4G network based on the Wi-Fi interface. This architecture defines several models corresponding, on the one hand, to Wi-Fi access controlled or not, On the other hand, to a handover controlled by the network or by the mobile. The integration of Wi-Fi technology resulted in a redefinition of attachment and session set-up procedures. Smartphones have the ability to activate simultaneously the two radio interfaces, LTE and Wi-Fi, which allows to direct certain services to one and / or the other of the interfaces. The ANDSF and HotSpot 2.0 functions provide the mobile with rules for network selection and traffic control to determine which traffic is to be routed to what type of interface.

Download or read book Ad Hoc Networks Telecommunications and Game Theory written by Malek Benslama and published by John Wiley & Sons. This book was released on 2015-01-20 with total page 166 pages. Available in PDF, EPUB and Kindle. Book excerpt: Random SALOHA and CSMA protocols that are used to access MAC in ad hoc networks are very small compared to the multiple and spontaneous use of the transmission channel. So they have low immunity to the problems of packet collisions. Indeed, the transmission time is the critical factor in the operation of such networks. The simulations demonstrate the positive impact of erasure codes on the throughput of the transmission in ad hoc networks. However, the network still suffers from the intermittency and volatility of its efficiency throughout its operation, and it switches quickly to the saturation zone. In this context, game theory has demonstrated his ability to lead the network to a more efficient equilibrium. This, we were led to propose our model code set that formalizes the behavior of nodes during transmission within SALOHA networks and CSMA respectively.

This book was released on 2015-02-16 with total page 230 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book provides a novel method based on advantages of mobility model of Low Earth Orbit Mobile Satellite System LEO MSS which allows the evaluation of instant of subsequent handover of a MS even if its location is unknown. This method is then utilized to propose two prioritized handover schemes, Pseudo Last Useful Instant PLUI strategy and Dynamic Channel Reservation DCR-like scheme based respectively on LUI and DCR schemes, previously proposed in literature. The authors also approach a different aspect of handover problem: calls with short durations dropped due to a handover failure. We propose a decision system based on fuzzy logic Rescuing System that allows the rescue of calls with short durations facing a premature at the expense of those lasting for long durations.

Download or read book New Telecom Networks written by Daniel Battu and published by John Wiley & Sons. This book was released on 2014-11-17 with total page 398 pages. Available in PDF, EPUB and Kindle. Book excerpt: Nowadays, the Internet has become an irreplaceable tool, feeding us information about new innovations and the evolution of the markets relating to all human activities. What the Internet lacks, though, is a guiding narrative thread, which is crucial to understand the evolution from old technologies into the technologies available today, and to benefit from the commentary which could elucidate that process of evolution. In spite of its inherent richness, no encyclopedia can constitute the one and only referential information source. The actors involved also have the right to be heard: all those who have devoted their working lives to the collective effort of edifying networks can, of course, present their personal views about the evolution of the world of telecommunications, and thus provide invaluable testimony to companies in this area who can make use of it. It is that approach which is adopted in this book. Whilst the primary objective of this book is to encourage SMEs to use digital technologies, and help them to organize with that goal in mind, it has proved necessary to describe the transformations currently under way in the field of networks, and to outline the efforts to obtain a competitive edge in terms of clerical applications, compare the various techniques that are available for high data rate communications, and touch upon the advent of the "Internet of Things", cloud computing and various new multimedia technologies. All in all, this book should help companies – particularly SMEs – to garner overall information about the current movement in the area of networking, and assist them in putting in place and managing their own communications systems.

Download or read book Dynamic Wireless Sensor Networks written by Sharief M. A. Oteafy and published by John Wiley & Sons. This book was released on 2014-08-08 with total page 153 pages. Available in PDF, EPUB and Kindle. Book excerpt: In this title, the authors leap into a novel paradigm of scalability and cost-effectiveness, on the basis of resource reuse. In a world with much abundance of wirelessly accessible devices, WSN deployments should capitalize on the resources already available in the region of deployment, and only augment it with the components required to meet new application requirements. However, if the required resources already exist in that region, WSN deployment converges to an assignment and scheduling scheme to accommodate for the new application given the existing resources. Such resources are polled from many fields, including multiple WSNs already in the field, static networks (WiFi, WiMAX, cellular, etc) in addition to municipal, industrial and mobile resources.The architecture, framework and pricing policy, as well as approaches for backward compatibility with existing deployments, are presented in this book. We elaborate on the formalization of the problem, and contrast with existing work on coverage. This paradigm adopts optimal assignments in WSNs and exploits dynamic re-programming for boosting post-deployment and backward compatible protocols.

Download or read book Software Defined Networking 2 written by Fetia Bannour and published by John Wiley & Sons. This book was released on 2023-01-12 with total page 180 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book reviews the concept of Software-Defined Networking (SDN) by studying the SDN architecture. It provides a detailed analysis of state-of-the-art distributed SDN controller platforms by assessing their advantages and drawbacks and classifying them in novel ways according to various criteria. Additionally, a thorough examination of the major challenges of existing distributed SDN controllers is provided along with insights into emerging and future trends in that area. Decentralization challenges in large-scale networks are tackled using three novel approaches, applied to the SDN control plane presented in the book. The first approach addresses the SDN controller placement optimization problem in large-scale IoT-like networks by proposing novel scalability and reliability aware controller placement strategies. The second and third approaches tackle the knowledge sharing problem between the distributed controllers by suggesting adaptive multilevel consistency models following the concept of continuous Quorum-based consistency. These approaches have been validated using different SDN applications, developed from real-world SDN controllers.
