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.

Download or read book Data Dissemination and Query in Mobile Social Networks written by Jiming Chen and published by Springer Science & Business Media. This book was released on 2012-03-27 with total page 91 pages. Available in PDF, EPUB and Kindle. Book excerpt: With the increasing popularization of personal hand-held mobile devices, more people use them to establish network connectivity and to query and share data among themselves in the absence of network infrastructure, creating mobile social networks (MSNet). Since users are only intermittently connected to MSNets, user mobility should be exploited to bridge network partitions and forward data. Currently, data route/forward approaches for such intermittently connected networks are commonly "store-carry-and-forward" schemes, which exploit the physical user movements to carry data around the network and overcome path disconnection. And since the source and destination may be far away from each other, the delay for the destination to receive the data from the source may be long. MSNets can be viewed as one type of socially-aware delay tolerant networks (DTNs). Observed from social networks, the contact frequencies are probably different between two friends and two strangers, and this difference should be taken into consideration when designing data dissemination and query schemes in MSNets. In this book, the fundamental concepts of MSNets are introduced including the background, key features and potential applications of MSNets, while also presenting research topics, such as, MSNets as realistic social contact traces and user mobility models. Because the ultimate goal is to establish networks that allow mobile users to quickly and efficiently access interesting information, particular attention is paid to data dissemination and query schemes in subsequent sections. Combined with geography information, the concepts of community and centrality are employed from a social network perspective to propose several data dissemination and query schemes, and further use real social contact traces to evaluate their performance, demonstrating that such schemes achieve better performance when exploiting more social relationships between users.

This book was released on 2011-11-25 with total page 539 pages. Available in PDF, EPUB and Kindle. Book excerpt: Complex Social Networks is a newly emerging (hot) topic with applications in a variety of domains, such as communication networks, engineering networks, social networks, and biological networks. In the last decade, there has been an explosive growth of research on complex real-world networks, a theme that is becoming pervasive in many disciplines, ranging from mathematics and computer science to the social and biological sciences. Optimization of complex communication networks requires a deep understanding of the interplay between the dynamics of the physical network and the information dynamics within the network. Although there are a few books addressing social networks or complex networks, none of them has specially focused on the optimization perspective of studying these networks. This book provides the basic theory of complex networks with several new mathematical approaches and optimization techniques to design and analyze dynamic complex networks. A wide range of applications and optimization problems derived from research areas such as cellular and molecular chemistry, operations research, brain physiology, epidemiology, and ecology.

Available in PDF, EPUB and Kindle. Book excerpt: In recent years, a lot of work has been done in an effort to incorporate Swarm Intelligence (SI) techniques in building an adaptive routing protocol for Mobile Ad Hoc Networks (MANETs). Since centralized approach for routing in MANETs generally lacks in scalability and fault-tolerance, SI techniques provide a natural solution through a distributed approach for the adaptive routing for MANETs. In SI techniques, the captivating features of insects or mammals are correlated with the real world problems to find solutions. Recently, several applications of bio-inspired and nature-inspired algorithms in telecommunications and computer networks have achieved remarkable success. The main aims/objectives of this book, "Mobile Ad Hoc Networks: Bio-Inspired Quality of Service Aware Routing Protocols", are twofold; firstly it clearly distinguishes between principles of traditional routing protocols and SI based routing protocols, while explaining in detail the analogy between MANETs and SI principles. Secondly, it presents the readers with important Quality of Service (QoS) parameters and explains how SI based routing protocols achieves QoS demands of the applications. This book also gives quantitative and qualitative analysis of some of the SI based routing protocols for MANETs.
