Available in PDF, EPUB and Kindle. Book excerpt: This thesis proposed and presented technical details of new probabilistic metrics of trust in the links wireless ad hoc networks for unobservable communications. In covert communication networks, only the end nodes are aware of the communication characteristics of the overall path. The most widely used protocols of ad hoc networks was overviewed. The routing protocols of ad hoc networks with trust considerations and select Destination Sequence Routing, a protocol that can be used in distributed ad hoc network settings for path discovery, was also reviewed. It establishes a path through which all packets sent by a source must pass to the destination. The end nodes are responsible for examining the statistics of the received packets and deriving inferences on path feature variations which are used for computing new trust metrics. When a path is judged not trustworthy based on the metrics, the Destination Sequence Routing is informed to undertake a new trusted path discovery between the end points. The thesis added a new feature based on the quality of service parameters of the path to create trust in the links in recognition of attacks.

Available in PDF, EPUB and Kindle. Book excerpt: In the second part of this dissertation, we turn our attention to the problem of reliable and trustworthy routing in mobile ad hoc networks. We consider the implications of applying our spatial approach to improve routing reliability through difficult terrains with possibly untrustworthy regions in tactical mobile ad hoc networks. The proposed approach provides maps of spatial reliability and trust, that reflect the probabilities for finding trustworthy routes between distinct locations. We develop a routing protocol, named "Reliability Map Routing" (RMR), which discovers routes over spatial cells whose local reliability and trust metrics are distributed throughout the network via a fast dissemination algorithm. Furthermore, the RMR protocol is capable of reliable geocasting with low overhead. Via QualNet simulation studies, we compare the performance of the RMR protocol in terms of packet delivery ratio, delay, and overhead, and quantify the effects of node density, velocity, and traffic load on these performance metrics.

Download or read book Mobile Ad Hoc Networks written by G Ram Mohana Reddy and published by CRC Press. This book was released on 2016-08-19 with total page 139 pages. 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.

Available in PDF, EPUB and Kindle. Book excerpt: A mobile ad hoc network (MANET) is a collection of two or more wireless devices with the capability to communicate with each other without the aid of any centralized administrator. Ad hoc networks have no fixed routers, these nodes can be connected dynamically in an arbitrary manner. MANETs, due to their operational characteristics, the dynamics of their changes and the precariousness of their resources, offer huge challenges due to the architecture and service nature in the next generation of mobile communications. MANETs play an important role in the future of next-generation networks. This special collection identifies and studies the most important concerns in MANETs, and includes contributions from researchers, academics, etc.
Download or read book A Method for Optimizing Power and Throughput Metrics for Mobile Ad Hoc Wireless Routing Algorithms written by Todd A. Newton and published by . This book was released on 2014 with total page 109 pages. Available in PDF, EPUB and Kindle. Book excerpt: Mobile ad hoc networks (MANET) are becoming increasingly popular, particularly in the realm of sensor networks. Most of the ongoing research of these networks is centered on protocol development and data delivery characteristics, particularly in the areas of throughput and latency. But in the realm of wireless networks, a new metric needs to be considered, one that takes into consideration the power efficiency across the wireless network. This thesis addresses this need by defining a new network performance metric that incorporates aspects of both power efficiency and data throughput. The new metric is a reflection of the performance of the routing protocol being evaluated for a particular network scenario. Comparing the metric values for different network routing protocols allow for the optimal network routing protocol for the particular network scenario to be identified. Wireless nodes have a finite amount of energy to operate with, and when that energy is depleted, the node dies and no longer performs its intended functions. In order to maintain a functioning MANET for longer periods of time, the network as a whole needs to consider power efficiency for optimal network lifetime. Some optimization techniques include transmission power, data compression, and even the network protocols used for network connectivity. Several of these techniques are discussed, but this research focuses more on the network routing protocols and the power footprints associated with them. While other researchers are developing power-aware routing algorithms, often by augmenting existing protocols, this thesis develops a methodology of comparing the overall network performance of the routing protocols used for a particular network scenario. Data is gathered through network simulations with ns-3, an open source network simulator. Four common routing protocols are evaluated against several network scenarios. Data collected per simulation includes the network lifetime and data throughput statistics. The data is analyzed in order to find the optimal routing protocol for the particular network scenario. Rather than creating yet another power-aware routing algorithm, this thesis develops a value-function based approach for measuring network performance that incorporates both power efficiency and data throughput.

Download or read book A Composite Trust Model for Secure Routing in Mobile Ad Hoc Networks written by Rutvij H. Jhaveri and published by . This book was released on 2017 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: It is imperative to address the issue of secure routing in mobile ad-hoc networks (MANETs) where the nodes seek for cooperative and trusted behaviour from the peer nodes in the absence of well-established infrastructure and centralized authority. Due to the inherent absence of security considerations in the traditional ad-hoc routing protocols, providing security and reliability in the routing of data packets is a major challenge. This work addresses this issue by proposing a composite trust metric based on the concept of social trust and quality-of-service (QoS) trust. Extended from the ad-hoc on-demand distance vector (AODV) routing protocol, we propose an enhanced trust-based model integrated with an attack-pattern discovery mechanism, which attempts to mitigate the adversaries craving to carry out distinct types of packet-forwarding misbehaviours. We present the detailed mode of operations of three distinct adversary models against which the proposed scheme is evaluated. Simulation results under different network conditions depict that the combination of social and QoS trust components provides significant improvement in packet delivery ratio, routing overhead, and energy consumption compared to an existing trust-based scheme.

This book was released on 2020-03-17 with total page 142 pages. Available in PDF, EPUB and Kindle. Book excerpt: Doctoral Thesis / Dissertation from the year 2016 in the subject Computer Science - Miscellaneous, grade: 16, , language: English, abstract: In this thesis, we have modified AODV routing protocol by incorporating link prediction algorithm using a proposed link prediction model. This algorithm predicts the link availability time and even before the link breaks; either it repairs the route locally or sends information to the source nodes to enable them to initiate a new route search well in time. This algorithm improves the quality of service of the network. Simulation results show that AODV routing algorithm with link availability model performs better than the existing AODV. Advances in wireless technology and hand-held computing devices have brought revolution in the area of mobile communication. The increasing mobility of humans across the globe generated demand for infrastructure-less and quickly deployable mobile networks. Such networks are referred to as Mobile Adhoc Networks (MANET). Usually, nodes in a MANET also act as a router while being is free to roam while communicating each others. Adhoc networks are suited for use in situations where infrastructure is unavailable or to deploy one is not cost-effective. Frequent changes in network topology due to mobility and limited battery power of the mobile devices are the key challenges in the adhoc networks. The depletion of power source may cause early unavailability of nodes and thus links in the network. The mobility of nodes will also causes frequent routes breaks and adversely affects the required performance for the applications. Availability of a route in future mainly depends on the availability of links between the nodes forming the route. Therefore, it is important to predict the future availability of a link that is currently available. We have proposed an analytical model for link prediction using Newton divided difference method. This link availability algorithm is incorporated in AODV routing algorithm (AODVLP) to evaluate the performance of AODV routing protocol using the metrics viz. delivery rate, average end-to-end delay, average RTS collisions per node and route failure. In the existing AODV protocol, packets are routed until a link in the existing path fails. This results in degradation of quality of service of network in terms of end-to-end delay and delivery ratio.

Book excerpt: 1. The increasing number of research papers appeared in the last years that either make use of aggregation functions or contribute to its theoretieal study asses its growing importance in the field of Fuzzy Logie and in others where uncertainty and imprecision play a relevant role. Since these papers are pub lished in many journals, few books and several proceedings of conferences, books on aggregation are partieularly welcome. To my knowledge, "Agrega tion Operators. New Trends and Applications" is the first book aiming at generality , and I take it as a honour to write this Foreword in response to the gentle demand of its editors, Radko Mesiar, Tomasa Calvo and Gaspar Mayor. My pleasure also derives from the fact that twenty years aga I was one of the first Spaniards interested in the study of aggregation functions, and this book includes work by several Spanish authors. The book contains nice and relevant original papers, authored by some of the most outstanding researchers in the field, and since it can serve, as the editors point out in the Preface, as a small handbook on aggregation, the book is very useful for those entering the subject for the first time. The book also contains apart dealing with potential areas of application, so it can be helpful in gaining insight on the future developments.
