Book excerpt: This open access book is the first to systematically introduce the principles of urban informatics and its application to every aspect of the city that involves its functioning, control, management, and future planning. It introduces new models and tools being developed to understand and implement these technologies that enable cities to function more efficiently – to become ‘smart’ and ‘sustainable’. The smart city has quickly emerged as computers have become ever smaller to the point where they can be embedded into the very fabric of the city, as well as being central to new ways in which the population can communicate and act. When cities are wired in this way, they have the potential to become sentient and responsive, generating massive streams of ‘big’ data in real time as well as providing immense opportunities for extracting new forms of urban data through crowdsourcing. This book offers a comprehensive review of the methods that form the core of urban informatics from various kinds of urban remote sensing to new approaches to machine learning and statistical modelling. It provides a detailed technical introduction to the wide array of tools information scientists need to develop the key urban analytics that are fundamental to learning about the smart city, and it outlines ways in which these tools can be used to inform design and policy so that cities can become more efficient with a greater concern for environment and equity.

Available in PDF, EPUB and Kindle. Book excerpt: While GPS is the de-facto solution for outdoor positioning with a clear sky view, there is no prevailing technology for GPS-deprived areas, including dense city centers, urban canyons, buildings and other covered structures, and subterranean facilities such as underground mines, where GPS signals are severely attenuated or totally blocked. As an alternative to GPS for the outdoors, indoor localization using machine learning is an emerging embedded and Internet of Things (IoT) application domain that is poised to reinvent the way we navigate in various indoor environments. This book discusses advances in the applications of machine learning that enable the localization and navigation of humans, robots, and vehicles in GPS-deficient environments. The book explores key challenges in the domain, such as mobile device resource limitations, device heterogeneity, environmental uncertainties, wireless signal variations, and security vulnerabilities. Countering these challenges can improve the accuracy, reliability, predictability, and energy-efficiency of indoor localization and navigation. The book identifies severalnovel energy-efficient, real-time, and robust indoor localization techniques that utilize emerging deep machine learning and statistical techniques to address the challenges for indoor localization and navigation. In particular, the book: Provides comprehensive coverage of the application of machine learning to the domain of indoor localization; Presents techniques to adapt and optimize machine learning models for fast, energy-efficient indoor localization; Covers design and deployment of indoor localization frameworks on mobile, IoT, and embedded devices in real conditions.

Available in PDF, EPUB and Kindle. Book excerpt: In recent years, rapid development in robotics, mobile, and communication technologies has encouraged many studies in the field of localization and navigation in indoor environments. An accurate localization system that can operate in an indoor environment has considerable practical value, because it can be built into autonomous mobile systems or a personal navigation system on a smartphone for guiding people through airports, shopping malls, museums and other public institutions, etc. Such a system would be particularly useful for blind people. Modern smartphones are equipped with numerous sensors (such as inertial sensors, cameras, and barometers) and communication modules (such as WiFi, Bluetooth, NFC, LTE/5G, and UWB capabilities), which enable the implementation of various localization algorithms, namely, visual localization, inertial navigation system, and radio localization. For the mapping of indoor environments and localization of autonomous mobile sysems, LIDAR sensors are also frequently used in addition to smartphone sensors. Visual localization and inertial navigation systems are sensitive to external disturbances; therefore, sensor fusion approaches can be used for the implementation of robust localization algorithms. These have to be optimized in order to be computationally efficient, which is essential for realtime processing and low energy consumption on a smartphone or robot.

Download or read book Improving the Speed and Accuracy of Indoor Localization written by Konstantinos Kleisouris and published by . This book was released on 2009 with total page 107 pages. Available in PDF, EPUB and Kindle. Book excerpt: Advances in technology have enabled a large number of computing devices to communicate wirelessly. In addition, radio waves, which are the primary means of transmitting data in wireless communication, can be used to localize devices in the 2D and 3D space. As a result there has been an increasing number of applications that rely on the availability of device location. Many systems have been developed to provide location estimates indoors, where Global Positioning System (GPS) devices do not work. However, localization indoors faces many challenges. First, a localization system should use as little extra hardware as possible, should work on any wireless device with very little or no modification, and localization latency should be small. Also, wireless signals indoors suffer from environmental effects like reflection, diffraction and scattering, making signal characterization with respect to location difficult. Moreover, many algorithms require detailed profiling of the environment, making the systems hard to deploy. This thesis addresses some of the aforementioned issues for localization systems that rely on radio properties like Received Signal Strength (RSS). The advantage of these systems is that they reuse the existing communication infrastructure, rather than necessitating the deployment of specialized hardware. Specifically, we improved the latency of a particular localization method that relies on Bayesian Networks (BNs). This method has the advantage of requiring a small size of training data, can localize many devices simultaneously, and some versions of BNs can localize without requiring the knowledge of the locations where signal strength properties are collected. We proposed Markov Chain Monte Carlo (MCMC) algorithms and evaluated their performance by introducing a metric which we call relative accuracy. We reduced latency by identifying MCMC methods that improve the relative accuracy to solutions returned by existing statistical packages in as little time as possible. In addition, we parallelized the MCMC process to improve latency when localizing devices whose number is on the order of hundreds. Finally, since wireless transmission is heavily affected by the physical environment indoors, we investigated the impact of using multiple antennas on the performance of various localization algorithms. We showed that deploying low-cost antennas at fixed locations can improve the accuracy and stability of localization algorithms indoors.

Available in PDF, EPUB and Kindle. Book excerpt: With the rapid development of Global Positioning Systems (GPS), the field location based services (LBS) is getting more and more attention. For indoor environments, LBS has a wide application for both civil and industrial areas. To make indoor LBS available, positioning technology has become a popular research topic in recent years. This dissertation investigates several indoor positioning topics based on visible light communication (VLC).First, it demonstrates the motivation to realize indoor LBS. Second, several positioning approaches are introduced to provide the location information. Positioning systems such as wireless local access network (WLAN), Zigbee, Bluetooth and radio frequency identification (RFID) are addressed. Third, fundamentals of VLC technology is detailed by explaining the light emitting diode (LED) as the transmitter, the photodiode (PD) as the receiver and the channel direct current (DC) gain considering the line-of-sight (LOS) condition. Visible light positioning systems are realized with lateration techniques based on received signal strength (RSS) information detected by PD. Two channel access methods are detailed and their advantages and disadvantages are analyzed. When height information of the receiver is unknown, three dimensional positioning is realized with an iterative algorithm based on the pre-estimation of the vertical coordinates. In order to further improve the positioning accuracy and alleviate the effect of large deviations, Kalman filter, particle filter as well as Gaussian mixture sigma point particle filter (GM-SPPF) are applied for both 2-D and 3-D scenarios. Considering the vertical accuracy cannot be improved largely from the filtering techniques, a nonlinear estimation algorithm is proposed based on a trust region algorithm.Multipath propagation is one of the most important factors that affects the performance of indoor positioning systems. In this dissertation, impulse response with multipath reflections are analyzed with the combined deterministic and modified Monte Carlo (CDMMC) algorithm. The received optical power from different LED bulbs and the positioning accuracy for the entire room is detailed. Orthogonal frequency division multiplexing (OFDM) is also proposed in the positioning system, considering OFDM performs well when multipath reflections exist. Positioning performance is largely improved with OFDM compared to On-off-keying (OOK) modulation. Finally, conclusions and future works are described in Chapter 9.
