Book Description
Wireless sensor networks have a range of applications, including military uses and in environmental monitoring. When an area of interest is inaccessible by conventional means, such a network can be deployed in ways resulting in a random distribution of the sensors. Randomly Deployed Wireless Sensor Networks offers a probabilistic method to model and analyze these networks. The book considers the network design, coverage, target detection, localization and tracking of sensors in randomly deployed wireless networks, and proposes a stochastic model. It quantifies the relationship between parameters of the network and its performance, and puts forward a communication protocol. The title provides analyses and formulas, giving engineering insight into randomly deployed wireless sensor networks. Five chapters consider the analysis of coverage performance; working modes and scheduling mechanisms; the relationship between sensor behavior and network performance properties; probabilistic forwarding routing protocols; localization methods for multiple targets and target number estimation; and experiments on target localization and tracking with a Mica sensor system. Details a probabilistic method to model and analyze randomly deployed wireless sensor networks Gives working modes and scheduling mechanisms for sensor nodes, allowing high-probability of target detection Considers the relationship between sensor behaviour and network performance and lifetime Offers probabilistic forwarding routing protocols for randomly deployed wireless sensor networks Describes a method for localizing multiple targets and estimating their number

Book Description
When choosing the technology options to develop a wireless sensor network (WSN), it is vital that their performance levels can be assessed for the type of application intended. This book describes the different technology options – MAC protocols, routing protocols, localisation and data fusion techniques – and provides the means to numerically measure their performance, whether by simulation, mathematical models or experimental test beds. Case studies, based on the authors’ direct experience of implementing wireless sensor networks, describe the design methodology and the type of measurements used, together with samples of the performance measurements attained. Wireless Sensor and Actuator Networks will enable you to answer vital questions such as: How long will my network remain alive given the amount of sensing required of it? For how long should I set the sleeping state of my motes? How many sensors should I distribute to meet the expected requirements of the application? What type of throughput should I expect as a function of the number of nodes deployed and the radio interface chosen (whether it be Bluetooth or Zigbee)? How is the Packet Error Rate of my Zigbee motes affected by the selection of adjacent frequency sub bands in the ISM 2.4GHz band? How is the localisation precision dependant on the number of nodes deployed in a corridor? Communications and signal processing engineers, researchers and graduate students working in wireless sensor networks will find this book an invaluable practical guide to this important technology. "This book gives a proper balance between theory and application; it is a book for those R&D engineers that want to appreciate both why, how and in which domains Wireless Sensor Networks can be best applied." --Fabio Bellifemine, Telecom Italia "This book is a thorough and accessible exposition on wireless sensor networks with a good balance between theory and practice; it is valuable for both students and practicing engineers, and is an essential addition for engineering libraries." --Professor Moe Win, Associate Professor at the Laboratory for Information and Decision Systems (LIDS), Massachusetts Institute of Technology Only book to examine wireless sensor network technologies and assess their performance capabilities against possible applications Enables the engineer to choose the technology that will give the best performance for the intended application Case studies, based on the authors’ direct experience of implementing wireless sensor networks, describe the design methodology and the type of measurements used, together with samples of the performance measurements attained

Book Description
This thesis report focuses on a new approach based on fuzzy logic systems to analyze the lifetime of a wireless sensor network. It demonstrates that a type-2 fuzzy membership function(MF), i.e., a Gaussian MF with uncertain standard deviation (std) is most appropriate to model a single node lifetime in wireless sensor networks. This research studies two basic sensor placement schemes: square-grid and hex-grid. Two fuzzy logic systems(FLSs): a singleton type-1 FLS and an interval type-2 FLS are designed to perform lifetime estimation of the sensor network. Simulation results show that the FLS offers a feasible method to analyze and estimate the sensor network lifetime and the interval type-2 FLS in which the antecedent membership functions are modeled as Gaussian with uncertain std outperforms the singleton type-1 FLS. In the later chapters, two energy efficient techniques in wireless sensor networks are presented: fuzzy optimization for distributed sensor deployment and spectrum efficient coding scheme for correlated non-binary sources in wirless sensor networks. For the sensor deployment topic, it is shown that given a finite number of sensors, optimizing the sensor deployment will provide sufficient sensor coverage and ameliorate the quality of communications. We apply fuzzy logic systems to optimize the sensor placement after an initial random deployment. Simulation results show that our approach achieves faster and stabler deployment and maximizes the sensor coverage with minimum energy consumption. Outage probability, as a measure of communication quality gets effectively decreased in our algorithm but it was not taken into consideration in the distributed self-spreading algorithm. In the case of correlated binary sources, distributed source coding has been literally studied in information theory. However, data sources from real sensor networks are normally non-binary. We proposed a spectrum efficient coding scheme for correlated non-binary sources in sensor networks. Our approach constructs the codeword cosets for the interested source, taking advantage of statistical characters of the distinct observations from sensor nodes. The wireless sensor technology can be applied to many real world applications. In this dissertation report, we present two applications when the sensor technology is used in the multi-target data fusion and underwater target positioning. In this work, we study the decision fusion rules of multiple fluctuating targets in multi-radar (MT-MR) sensor networks. The MT-MR decision fusion problem is modeled as a multi-input multi-output (MIMO) system. We assume that each radar makes binary decision for each target from the observation, i.e. if the target is present or not. We derive our MIMO fusion rules based on the target fluctuation model and compare against the optimal likelihood ratio method (LR), maximum ratio combiner (MRC) and equal gain combiner (EGC). Simulation results show that the MIMO fusion rules approach the optimal-LR and outperforms MRC and EGC at high signal to clutter ratio (SCR). In Chapter 6, we present a silent positioning scheme termed as UPS for underwater acoustic sensor networks. UPS relies on the time-difference of arrivals measured locally at a sensor to detect range differences from the sensor to four anchor nodes. These range differences are averaged over multiple beacon intervals before they are combined to estimate the 3D sensor location through trilateration. UPS requires no time-synchronization and provides location privacy at underwater vehicles/sensors whose locations need to be determined. To study the performance of UPS, we model the underwater acoustic channel as a modified Ultra Wide Band (UWB) S-V model: the arrival of each path cluster and paths within each cluster follow double Poisson distributions, and the multipath channel gain follows a Rician distribution. Based on this channel model, we perform both theoretical analysis and simulation study on the position error of UPS under acoustic fading channels. The obtained results indicate that UPS is an effective scheme for underwater vehicle/sensor self-positioning. (Abstract shortened by UMI.).

Book Description
This book highlights both theoretical and applied advances in cellular learning automata (CLA), a type of hybrid computational model that has been successfully employed in various areas to solve complex problems and to model, learn, or simulate complicated patterns of behavior. Owing to CLA’s parallel and learning abilities, it has proven to be quite effective in uncertain, time-varying, decentralized, and distributed environments. The book begins with a brief introduction to various CLA models, before focusing on recently developed CLA variants. In turn, the research areas related to CLA are addressed as bibliometric network analysis perspectives. The next part of the book presents CLA-based solutions to several computer science problems in e.g. static optimization, dynamic optimization, wireless networks, mesh networks, and cloud computing. Given its scope, the book is well suited for all researchers in the fields of artificial intelligence and reinforcement learning.
