Available in PDF, EPUB and Kindle. Book excerpt: "Delay Tolerant Networks (DTNs) were originally intended for interplanetary communications and have been applied to a series of difficult environments: wireless sensor networks, unmanned aerial vehicles, and short-range personal communications. There is a class of such environments in which nodes follow semi-predictable social patterns, such as wildlife tracking or personal devices. This work introduces a series of algorithms designed to identify the social patterns present in these environments and apply this data to difficult problems, such as efficient message routing and content distribution. Security is also difficult in a mobile environment. This is especially the case in the event that a large portion of the network is unreliable, or simply unknown. As the network size increases nodes have difficulty in securely distributing keys, especially using low powered nodes with limited keyspace. A series of multi-party security algorithms were designed to securely transmit a message in the event that the sender does not have access to the destinations public key. Messages are routed through a series of nodes, each of which partially decrypts the message. By encrypting for several proxies, the message can only be intercepted if all those nodes have been compromised. Even a highly compromised network has increased security using this algorithm, with a trade-off of reduced delivery ratio and increased delivery time"--Abstract, page iv.

Book Synopsis A Secure Socially-Aware Content Retrieval Framework for Delay Tolerant Networks by : Tuan Vu Le
Download or read book A Secure Socially-Aware Content Retrieval Framework for Delay Tolerant Networks written by Tuan Vu Le and published by . This book was released on 2016 with total page 183 pages. Available in PDF, EPUB and Kindle. Book excerpt: Delay Tolerant Networks (DTNs) are sparse mobile ad-hoc networks in which there is typically no complete path between the source and destination. Content retrieval is an important service in DTNs. It allows peer-to-peer data sharing and access among mobile users in areas that lack a fixed communication infrastructure such as rural areas, inter-vehicle communication, and military environments. There are many applications for content retrieval in DTNs. For example, mobile users can find interesting digital content such as music and images from other network peers for entertainment purposes. Vehicles can access live traffic information to avoid traffic delay. Soldiers with wireless devices can retrieve relevant information such as terrain descriptions, weather, and intelligence information from other nodes in a battlefield. In this dissertation, we propose the design of a secure and scalable architecture for content retrieval in DTNs. Our design consists of five key components: (1) a distributed content discovery service, (2) a routing protocol for message delivery, (3) a buffer management policy to schedule and drop messages in resource-constrained environments, (4) a caching framework to enhance the performance of data access, and (5) a mechanism to detect malicious and selfish behaviors in the network. To cope with the unstable network topology due to the highly volatile movement of nodes in DTNs, we exploit the underlying stable social relationships among nodes for message routing, caching, and placement of the content-lookup service. Specifically, we rely on three key social concepts: social tie, centrality, and social level. Centrality is used to form the distributed content discovery service and the caching framework. Social level guides the forwarding of content requests to a content discovery service node. Once the content provider ID is discovered, social tie is exploited to deliver content requests to the content provider, and content data to the requester node. Furthermore, to reduce the transmission cost, we investigate and propose routing strategies for three dominant communication models in DTNs: unicast (a content is sent to a single node), multicast (a content is sent to multiple nodes), and anycast (a content is sent to any one member in a group of nodes). We also address several security issues for content retrieval in DTNs. In the presence of malicious and selfish nodes, the content retrieval performance can be deteriorated significantly. To address this problem, we use Public Key Cryptography to secure social-tie records and content delivery records during a contact between two nodes. The unforgeable social-tie records prevent malicious nodes from falsifying the social-tie information, which corrupts the content lookup service placement and disrupts the social-tie routing protocol. The delivery records from which the packet forwarding ratio of a node is computed, helps detect selfish behavior. Furthermore, we propose a blacklist distribution scheme that allows nodes to filter out misbehaving nodes from their social contact graph, effectively preventing network traffic from flowing to misbehaving nodes. Through extensive simulation studies using real-world mobility traces, we show that our content retrieval scheme can achieve a high content delivery ratio, low delay, and low transmission cost. In addition, our proposed misbehavior detection method can detect insider attacks efficiently with a high detection ratio and a low false positive rate, thus improving the content retrieval performance.

Book Synopsis Designing Efficient Routing Protocols in Delay Tolerant Networks by : Yunsheng Wang
Download or read book Designing Efficient Routing Protocols in Delay Tolerant Networks written by Yunsheng Wang and published by . This book was released on 2013 with total page 177 pages. 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.

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.

Download or read book Social-based Data Routing Strategies in Delay Tolerant Networks written by and published by . This book was released on 2014 with total page 107 pages. Available in PDF, EPUB and Kindle. Book excerpt: Delay Tolerant networks (DTNs) are intermittently connected mobile networks in which the end-to-end paths do not exist. Data delivery in such networks relies upon the contacts that use "store-carry-and-forward" paradigm to forward message from one node to another. However, such intuitive methodology encounters low message delivery ratio and high data transmission delay when applying to different data routing strategies. The design of effective and efficient data routing strategies based on limited knowledge of mobile nodes in DTNs is challenging. In this dissertation, we explore several asp...
