Resilience In Communication Networks

Given Society's increasing dependence on communication networks, the Internet and their services, vulnerabilities of communication networks and the Internet can significantly impact our lives. The dependence on communication networks and the Internet makes them an attractive target for attacks and intrusions attempting to either obtain information or disrupt service of individuals, businesses, government and military. These networks and services are also susceptible to accidents, faults or natural disasters that can disrupt service. In the face of these difficulties, the need for greater resilience has been recognized for wireline and wireless networks and for the Internet. Resilience has classically been defined as the ability of the network to provide and maintain an acceptable level of service in the face of faults, accidents, attacks and natural disasters. Today, resilience can be considered an essential characteristic in the design and operation of networks to withstand the intrusions described above. Furthermore, we must now expand resilience to include new requirements, such as scalability, dynamic and opportunistic topologies, and global interoperation and interdependence among networks. This book presents the characteristics of resilient communication networks, highlighting existing communication technologies that can be employed to dependence on communication networks, the Internet and their services, vulnerabilities of communication networks can significantly impact our lives. Hence, it is a prominent interest to create solutions to keep the communication resilient to accidents, faults or natural disasters that can disrupt service. Resilience has classically been defined as the ability of the network to provide and maintain an acceptable level of service in the face of faults, accidents, attacks and natural disasters. Today, resilience can be considered an essential characteristic in the design and operation of networks to withstand vulnerabilities described above. Furthermore, we must now expand resilience to include new requirements, such as scalability, dynamic and opportunistic topologies, and global interoperation and interdependence among networks. This book present few examples related to the design of resilience solutions taking into account those new requirements.

The work highlights the main causes of failures of network nodes and links, and presents an overview of resilient routing mechanisms, covering issues related to the Future Internet (FI), wireless mesh networks (WMNs), and vehicular ad-hoc networks (VANETs). For each of these network architectures, a selection of novel approaches are described, followed by evaluation of their characteristics. Topics and features: Discusses FI architecture for network virtualization, examining the network resource provisioning necessary to provide network resilience Introduces proposals for dedicated and shared protection in random failure scenarios and against malicious activities Describes measures for WMN survivability that allow for evaluation of performance under multiple failures Proposes a new scheme to enable proactive updates of WMN antenna alignment to prepare the network in advance for changing weather conditions Includes a detailed analysis of the differentiated reliability requirements for VANET applications, with a focus on issues of multi-hop data delivery Reviews techniques for improving the stability of end-to-end VANET communication paths based on multipath routing and anycast forwarding Researchers and practitioners interested in contemporary and future communication network architectures, from both academia and industry, will find this to be a must-read work on issues of end-to-end resilient routing. Dr. Jacek Rak is an Assistant Professor in the Department of Computer Communications at the Faculty of Electronics, Telecommunications, and Informatics of Gdansk University of Technology, Poland.

This book is devoted to the probabilistic description of the behavior of a network in the process of random removal of its components (links, nodes) appearing as a result of technical failures, natural disasters or intentional attacks. It is focused on a practical approach to network reliability and resilience evaluation, based on applications of Monte Carlo methodology to numerical approximation of network combinatorial invariants, including so-called multidimensional destruction spectra. This allows to develop a probabilistic follow-up analysis of the network in the process of its gradual destruction, to identify most important network components and to develop efficient heuristic algorithms for network optimal design. Our methodology works with satisfactory accuracy and efficiency for most applications of reliability theory to real –life problems in networks.
