Download or read book Reliable Data Delivery Protocols for Underwater Sensor Networks written by Nusrat Nowsheen and published by . This book was released on 2015 with total page 318 pages. Available in PDF, EPUB and Kindle. Book excerpt: Underwater Acoustic Sensor Networks (UASNs) are becoming increasingly promising to monitor aquatic environment. The network is formed by deploying a number of sensor nodes and/or Autonomous Underwater Vehicles (AUVs) to support diverse applications such as pollution monitoring, oceanographic data collection, disaster recovery and surveillance. These applications require transmission of data packets from the source to a sink or gateway in a multihop fashion and eventually to a message ferry or an onshore station. In such a network, reliable data delivery becomes challenging as delivery is hindered due to long propagation delay and high error-rate of underwater acoustic channel, limited energy and inherent mobility of sensor nodes. Existing data delivery protocols have certain limitations such as predefined communication architecture, dependency on periodic communication with neighbors or flooding-based data forwarding. These restrict their capabilities to achieve reliable delivery in many application scenarios. They mainly consider location, depth and energy information of sensor nodes to improve energy efficiency of underwater networks. However, to improve reliability, protocols should consider factors such as link quality, node movement, packet delay and traffic flow so that they can deal with the disruptive nature of the communication link, and harsh and dynamic context of the network.In this thesis, we focus on developing data delivery protocols to provide reliable data transfer for various underwater applications and network scenarios considering underwater communication characteristics that have direct impact on reliable data transfer. In the first protocol, an anchor-based architecture is considered to support underwater monitoring applications and mobile message ferry nodes are used to collect stored data from one or more nodes, called gateways. A strategy for gateway selection is devised to maximize their lifetime. Data delivery reliability is significantly improved by selecting the next hop forwarder on-the-fly based on its link reliability and reachability to gateways through probabilistic estimation. Data forwarding solution is coupled with delay tolerant networking paradigm by accumulating data packets for a fixed amount of "hold time" to improve delivery and reduce communication overhead simultaneously. Besides high error probability and dynamic nature of underwater acoustic channel, node movement also makes data forwarding process difficult. Moreover, consideration of network condition in the calculation of "hold time" captures more recent network status. The first protocol is therefore further extended by (i) estimating/predicting node movement pattern and using it to determine neighbors' coverage probability, and (ii) calculating data "hold time" dynamically at each node. Consideration of the above factors increases the reliability of data forwarding solution. The above protocols have been designed to improve reliability of data transfer for underwater monitoring applications. However, in many situations like disaster management and emergency rescue operations in ocean, deployment of an ad hoc network consisting of AUVs is of paramount importance to support mission critical applications. To accomplish this, an effective data delivery protocol has been devised which ensures reliability by delivering data within a given deadline to the onshore station using a set of AUVs. A modified Breadth-First Search (BFS) technique has been employed to find a path towards an AUV that meets the data delivery deadline as per a given surfacing schedule. A command-based node movement technique has been incorporated to ensure delivery in an energy efficient manner. The proposed data delivery protocols have been evaluated and compared with existing relevant and contemporary underwater protocols. Simulation results show that the proposed protocols achieve performance improvement over competing protocols in terms of successful packet delivery, communication overhead and energy.

This book was released on 2014 with total page 145 pages. Available in PDF, EPUB and Kindle. Book excerpt: Underwater communication and networks will play a major role in many future commercial, environmental, and military applications, including disaster prevention, tactical surveillance, offshore exploration, pollution monitoring, tsunami detection, sunken airplane or vessel localization and oceanographic data collection. Acoustic wireless communication is the transmission technology of choice for underwater networked systems. However, underwater acoustic signals propagating in water suffer from significant path loss, time-varying multipath propagation, Doppler spread, and high propagation delay. These formidable challenges limit the available bandwidth for underwater acoustic communications, while the rapidly varying channel results in communication links that are highly unreliable, ultimately hindering advancements in underwater networked communications. As a consequence, the field of underwater communication and networking is still in its infancy. The objective of this research work is to further push the boundaries in underwater communication and networking by developing a versatile reconfigurable underwater networking platform, analyzing the statistical channel properties of short-range shallow water communication environments and exploring advanced signal processing techniques to improve the network throughput, provide a secure communication means, and offer a low-cost distributed networked localization and time synchronization framework for underwater acoustic networks. Specifically, in this dissertation, we first present the development of a software-defined underwater networking testbed we developed at the University at Buffalo. In the second part of this work, we investigate underwater acoustic channel characteristics in short-range shallow water environments. In the third part, we propose CDMA-based analog network coding for underwater acoustic sensor networks with the objective to improve the network throughput. In the forth part, we explore CDMA-based analog network coding to provide a secure underwater acoustic communications means. Finally, in the fifth part of this work, we propose a low-cost distributed networked localization and time synchronization framework for underwater acoustic testbeds.

Available in PDF, EPUB and Kindle. Book excerpt: Ocean covers 70.8% of the Earth’s surface, and it plays an important role in supporting all life on Earth. Nonetheless, more than 80% of the ocean’s volume remains unmapped, unobserved and unexplored. In this regard, Underwater Sensor Networks (USNs), which offer ubiquitous computation, efficient communication and reliable control, are emerging as a promising solution to understand and explore the ocean. In order to support the application of USNs, accurate position information from sensor nodes is required to correctly analyze and interpret the data sampled. However, the openness and weak communication characteristics of USNs make underwater localization much more challenging in comparison to terrestrial sensor networks. In this book, we focus on the localization problem in USNs, taking into account the unique characteristics of the underwater environment. This problem is of considerable importance, since fundamental guidance on the design and analysis of USN localization is very limited at present. To this end, we first introduce the network architecture of USNs and briefly review previous approaches to the localization of USNs. Then, the asynchronous clock, node mobility, stratification effect, privacy preserving and attack detection are considered respectively and corresponding localization schemes are developed. Lastly, the book’s rich implications provide guidance on the design of future USN localization schemes. The results in this book reveal from a system perspective that underwater localization accuracy is closely related to the communication protocol and optimization estimator. Researchers, scientists and engineers in the field of USNs can benefit greatly from this book, which provides a wealth of information, useful methods and practical algorithms to help understand and explore the ocean.
