Improving the Reliability of Underwater Communication

Telemetry or wireless communication is the obvious choice, but radio does not work under water. As alternative, acoustic signals are prone to disruptions and sometimes complete failure. This highlights some of the major challenges with submarine information and communications technology (ICT).

Under good conditions currently available subsea modems can perform their role satisfactorily. However, when the hydro-acoustic conditions get worse due to interfering noise, varying multi-path propagations and other factors, communications may and often do fail. Even in calm seas, the stratification of the water body can cause severe signal reverberations and dynamic fluctuation of the channel properties, resulting in poor transmissions. Thus, a real innovation was needed to provide reliable wireless communication under varying conditions.

New approaches employ a continuous change of frequencies that not only serves to transmit information, but also to compensate for sources of interference, such as echoes and noise. Acoustic underwater modems that “sing” like whales and dolphins in the ultrasonic range are able to reliably transmit digital data over distances up to several kilometers with no data loss or harm to the environment.

This way, the signal energy is continuously spread over a wide range of frequencies and the signal structure is adapted so that the multi-path components do not interfere with each other. At the receiver side, advanced signal processing collects the energy and converts the received signals into narrow-band signals.

Sweep Spread Carrier (S2C) is a technology that continuously spreads the signal energy over a wide range of frequencies and adapts the signal structure so that the multipath components do not interfere with each other. At the receiver side, advanced signal processing collects the energy and converts the received signals into narrow-band signals. Taking advantage of the ultra-wideband sweep technology the subsea modems continuously determine the signal propagation time and Doppler shift with a high accuracy, which at the same time intrinsically provide the precise distance and relative velocity between modem pairs. Long and short-baseline positioning or tracking mobile systems (AUVs, remotely operated vehicles [ROVs], robots) are simplified.

Complex communication, navigation and monitoring networks can be established. Each modem is able to be individually addressed, and at each connection to another address it calculates the distance and relative velocity and evaluates the acoustic properties of that channel. Sharing these data with other nodes enables optimal traffic planning and routing in the network.

Algorithms For Coalition Formation In Multi-Agents Systems $71.27 Software agents situated in the same environment typically need to interact with one another in order to fulfill their objectives or improve their performance. Coalition formation is a fundamental form of interaction that has proven to be useful in a number of scenarios, including:- sensor networks;- e-commerce;- distributed vehicle routing.Forming effective coalitions is a major research challenge in the field of multi-agent systems. Central to this endeavour is the problem of determining which of the potential coalitions to form in order to achieve some goal.This usually requires calculating a value for every coalition, known as the coalition value, which indicates how beneficial that coalition would be if it was formed. Once these values are calculated, the agents need to find a combination of coalitions of which the sum of values is maximized, and in which every agent belongs to exactly one coalition.Finding an optimal, or near-optimal, solution to this coalition structure generation problem is extremely challenging due to the large number of possible solutions. To date, many algorithms have been proposed to solve this problem using different techniques – ranging from dynamic programming, to integer programming, to stochastic search – all of which suffer from major limitations relating to execution time, solution quality, and memory requirements.Against this background, this thesis presents a novel algorithm for distributing the coalition-value calculations among the agents. The algorithm is decentralized, requires no communication between the agents, has minimal memory requirements, and can reflect variations in the computational speeds of the agents. We also develop an anytime algorithm for coalition structure generation. By using a novel representation of the search space, and by applying branch-and-bound techniques, the algorithm is shown to significantly outperform other existing ones in the lit

An adaptive jam-resistant cross-layer protocol for mobile ad-hoc networks in noisy environments. $69 This dissertation contributes a jam-resistant communications protocol for use in a mobile ad-hoc network (MANET). Specific focus is given to the network layer routing of packets within a MANET. A MANET is a self-organizing multi-hop wireless network that is comprised of many mobile hosts communicating wirelessly. As a result of their mobility and dependence on wireless communications, network layer routing is especially prone to errors. An algorithm has been developed using the concept of concurrent codes to allow for jam-resistant wireless communications without a pre-shared secret. The algorithm allows for the recovery of messages even in the presence of significant noise. Experimental results show that a cross-layer protocol designed to take advantage of this property allows for more effective communications in noisy environments such as disaster sites where current network protocols experience significant packet loss rates. Ultimately, this research presents a communications protocol that adapts to the level of interference in the environment to which the network is deployed to allow for effective communication.

Cisco Router and Switch Forensics: Investigating and Analyzing Malicious Network Activity $59.95 Cisco IOS (the software that runs the vast majority of Cisco routers and all Cisco network switches) is the dominant routing platform on the Internet and corporate networks. This widespread distribution, as well as its architectural deficiencies, makes it a valuable target for hackers looking to attack a corporate or private network infrastructure. Compromised devices can disrupt stability, introduce malicious modification, and endanger all communication on the network. For security of the network and investigation of attacks, in-depth analysis and diagnostics are critical, but no book currently covers forensic analysis of Cisco network devices in any detail. Cisco Router and Switch Forensics is the first book devoted to criminal attacks, incident response, data collection, and legal testimony on the market leader in network devices, including routers, switches, and wireless access points. Why is this focus on network devices necessary? Because criminals are targeting networks, and network devices require a fundamentally different approach than the process taken with traditional forensics. By hacking a router, an attacker can bypass a network’s firewalls, issue a denial of service (DoS) attack to disable the network, monitor and record all outgoing and incoming traffic, or redirect that communication anywhere they like. But capturing this criminal activity cannot be accomplished with the tools and techniques of traditional forensics. While forensic analysis of computers or other traditional media typically involves immediate shut-down of the target machine, creation of a duplicate, and analysis of static data, this process rarely recovers live system data. So, when an investigation focuses on live network activity, this traditional approach obviously fails. Investigators must recover data as it is transferred via the router or switch, because it is destroyed when the network device is powered down. In this case, following the traditional approach outlined in

Communication Networking: An Analytical Approach $57.76 “This book combines an innovative and uniform representation of a variety of communication networks, simple to understand motivations for real design problems for these networks, intuitive approaches to solutions, and rigorous mathematical analysis where appropriate. It will be very valuable both as a textbook and as a reference for practitioners.”–Bharat Doshi, Director of Transformational Communication, Johns Hopkins University, Applied Physics Laboratory”It has been very difficult to write a textbook on networking that is relevant and rigorous because the field is diverse and fast changing. This book stands out in both providing the readers with the essential domain knowledge and equipping them with fundamental tools to analyze and design new systems as the networking field evolves.”–Steven Low, Associate Professor, California Institute of Technology”This book is a well-researched compendium of theoretical modeling applied to a number of practical networking problems. Some interesting topics of note are important insights in the design of packet switches, performance of TCP under various conditions, and the design of packet address prefix lookups. Although much of the material is mathematically advanced, the book contains a comprehensive set of appendices useful as a reference for the researcher or advanced practitioner.”–Dr. David E. McDysan, Fellow, MCI Internet Architecture and TechnologyThe viewpoint is that communication networking is about efficient resource sharing. The focus is on the three building blocks of communication networking, namely, multiplexing, switching and routing. The approach is analytical, with the discussion being driven by mathematical analyses of and solutions to specific engineering problems.The result?

Interconnection Networks and Mapping and Scheduling Parallel Computations: Dimacs Workshop, February 7-9, 1994 $5.25 Used – The interconnection network is one of the most basic components of a massively parallel computer system. Such systems consist of hundreds or thousands of processors interconnected to work cooperatively on computations. One of the central problems in parallel computing is the task of mapping a collection of processes onto the processors and routing network of a parallel machine. Once this mapping is done, it is critical to schedule computations within and communication among processors so

Introduction to Distributed Algorithms $63.48 The lower cost and increased flexibility and availability of computer networks means they are rapidly replacing centralized ‘mainframes’. The implementation of networked systems and the control of applications running in them require, however, the design of new techniques and methods, collectively known as distributed algorithms.In this textbook Professor Tel provide a clear yet rigorous introduction to a large collection of these methods and related theory largely developed over the last 15 years. He concentrates on algorithms for the point-to-point message passing model and includes algorithms for the implementation of computer communication networks (i.e. routing, data transmission and connection management, techniques for avoiding deadlock). Other key areas discussed are algorithms for the control of distributed applications (wave, broadcast, election, termination detection, randomized algorithms for anonymous networks, snapshots, deadlock detection, synchronous systems) and fault-tolerance achievable by distributed algorithms (possibility or otherwise in asynchronous systems, consensus in synchronous systems, authentication, synchronization, stablizing algorithms).Developed from lectures given to undergraduate and graduate students this textbook comes complete with examples and exercises with solutions, but the treatment of algorithms is deep enough to ensure that it will be useful for practicing engineers and scientists.

Load balancing routing in multi-hop wireless networks. $69 Multi-hop wireless networks have attracted significant interests in recent years because of the improved flexibility, mobility and low-cost compared to wired networks. Routing in multi-hop wireless networks has been heavily studied in the last decade and numerous routing protocols were proposed in literature. Most current wireless routing protocols are based on Shortest Path Routing (SPR) where packets are delivered along the shortest route from a source to a destination. Even for geographical localized routing protocols, such as the greedy routing, the packets usually follow the shortest paths between sources and destinations when the network is dense and uniformly distributed. Taking the shortest path can achieve smaller delay or traveled distance. However, under uniform communication shortest path routing suffers from uneven load distribution in the network, such as crowded center effect where the center nodes have much heavier load than the nodes in the periphery. We propose a novel routing method, called Circular Sailing Routing (CSR) seeking to distribute the traffic more evenly in the network. The proposed method first maps the network onto a sphere via a simple stereographic projection. Then the route decision is made by the spherical distance on the sphere instead of the Euclidean distance in the plane. By spreading the traffic across a virtual sphere, CSR can diminish the crowded center effect and increase the energy lifetime of the network. CSR can be easily implemented by using current position-based routing protocol without any major changes or additional overhead. The only modification is a simple mapping calculation of the position information. We theoretically prove that for a network the distance traveled by the packets using CSR is no more than a small constant factor of the minimum (the distance of the shortest path). We call this factor as Competitiveness Factor. We then extend CSR to a localized version, Localized CSR, by modifying the greedy
