Book excerpt: This brief presents emerging and promising communication methods for network reliability via delay tolerant networks (DTNs). Different from traditional networks, DTNs possess unique features, such as long latency and unstable network topology. As a result, DTNs can be widely applied to critical applications, such as space communications, disaster rescue, and battlefield communications. The brief provides a complete investigation of DTNs and their current applications, from an overview to the latest development in the area. The core issue of data forward in DTNs is tackled, including the importance of social characteristics, which is an essential feature if the mobile devices are used for human communication. Security and privacy issues in DTNs are discussed, and future work is also discussed.

This book was released on 2013-06 with total page 32 pages. Available in PDF, EPUB and Kindle. Book excerpt: Delay-Tolerant Networking (DTN) is an active area of research in the space communications community. DTN uses a standard layered approach with the Bundle Protocol operating on top of transport layer protocols known as convergence layers that actually transmit the data between nodes. Several different common transport layer protocols have been implemented as convergence layers in DTN implementations including User Datagram Protocol (UDP), Transmission Control Protocol (TCP), and Licklider Transmission Protocol (LTP). The purpose of this paper is to evaluate several stand-alone implementations of negative-acknowledgment based transport layer protocols to determine how they perform in a variety of different link conditions. The transport protocols chosen for this evaluation include Consultative Committee for Space Data Systems (CCSDS) File Delivery Protocol (CFDP), Licklider Transmission Protocol (LTP), NACK-Oriented Reliable Multicast (NORM), and Saratoga. The test parameters that the protocols were subjected to are characteristic of common communications links ranging from terrestrial to cis-lunar and apply different levels of delay, line rate, and error.

Available in PDF, EPUB and Kindle. Book excerpt: This cutting-edge resource provides a comprehensive treatment of applying delay-tolerant networking (DTN) principles to satellite-based network communications. Detailed models and analytical tools are used to evaluate performance and provide guidance in the field. This book presents the state-of-the-art in existing on-board and ground technologies that support satellite applications, such as communications protocols, algorithms, and security procedures. Readers gain key insight into the fundamental concepts of DTN applied to satellite networks (DTSNs) and case studies are provided. This book presents an authoritative introduction to the methods for computing metrics for satellite network modeling. Satellite communications are examined, including satellite links, communication protocols, and distributed multiple access schemes, such as time division, code division, and frequency division. This book focuses on ways in which DTN might make terrestrial communication and observation via earth orbiting satellites less expensive and more robust. The fundamental concepts and analysis of the Ring Road Architecture are explored. Unique analyses on the motivating factors of using Inter-Satellite Links (ISL) to form networks in disruptive environments in space are discussed. This book explores the limits of larger and complex DTSNs as the number of satellites increase and different orbital formations become possible. As satellite networks become larger in upcoming years this book provides a guide for readers to stay informed about standard protocols such as DTN that will allow seamless interoperation, cost reduction, and risk mitigation.

Available in PDF, EPUB and Kindle. Book excerpt: Delay-Tolerant Networks (DTNs) are a type of emerging networks characterized by very long delay paths, frequent network partitions and high loss rates. The nodes are sparsely deployed and intermittently connected. The presenting network is used in a variety of environments including military, disaster situations and for long distance communications. Although it is used in critical sectors, the communication support lacks the high end technology usually found in important networks. The nodes participating in this network do not have stable end-to-end connections. They can communicate to each other only occasionally, through the opportunistically available links. Thus, routing becomes one of the most challenging problems. On the other hand, the Ripple Routing protocol (RPL) was introduced by a working group called Routing Over Low and Lossy Networks (ROLL) and aimed to be used as a routing protocol over Low and Lossy Networks (LLN). This thesis aims to find a suitable protocol that can be applied to Delay tolerant Networks in order to improve and optimize the routing and to lower the delay and loss of packets between the nodes. Since the ROLL/RPL protocol is specialized for the Low power and Lossy Networks; therefore it could include Delay Tolerant Networks as well. However, the ROLL/RPL protocol was mainly designed for dense wireless networks. On the other hand, a mobile DTN does not have much in common with a dense "always on" network. Therefore, we decided in this thesis to investigate the applicability of the ROLL/RPL on a DTN, and to calculate its efficiency depending on the network density. This thesis shall provide recommendations on how this protocol could be upgraded to suit sparse Low and Lossy Networks (LLNs).

Available in PDF, EPUB and Kindle. Book excerpt: This thesis presents the design and evaluation of routing protocols for efficient content delivery and dissemination in delay tolerant networks. With the advancement in technology, the communication devices with wireless interfaces become more and more universal. Delay tolerant networks (DTNs) are characterized by intermittent connectivity and limited network capacity. There exist several different application scenarios: connectivity of developing countries, vehicular DTN road communications, and social contact networks. In this thesis, we explore the characteristics in DTNs, such as mobility pattern, contact history information, and social feature information, to design efficient routing schemes. The research reported in this thesis investigates the technical challenges and their solutions of applying different DTN routing protocols. We design multicast schemes to forward the information to a group of destinations in DTN environment. We extend the delegation forwarding scheme in DTN multicasting. An non-replication multicast tree is also studied in this report. We also apply ticket-based and social-tie-based approaches in content distribution systems. We leverage the users' social feature information to study the hypercube-based routing schemes in social contact networks. We also study the resource management problem in DTNs. We design a joint replication-migration-based scheme to solve the storage congestion. These techniques are evaluated comprehensively in realistic simulation studies, by comparing the performance with state-of-the-art approaches in both synthetic and real traces.
Download or read book Delay and Disruption Tolerant Networks written by Aloizio Pereira da Silva and published by CRC Press. This book was released on 2018-09-04 with total page 487 pages. Available in PDF, EPUB and Kindle. Book excerpt: Delay- and Disruption Tolerant Networks (DTNs) are networks subject to arbitrarily long-lived disruptions in connectivity and therefore cannot guarantee end-to-end connectivity at all times. Consequently DTNs called for novel core networking protocols since most existing Internet protocols rely on the network’s ability to maintain end-to-end communication between participating nodes. This book presents the fundamental principles that underline DTNs. It explains the state-of-the-art on DTNs, their architecture, protocols, and applications. It also explores DTN’s future technological trends and applications. Its main goal is to serve as a reference for researchers and practitioners.
