Providing Location Services in the Ubiquitous Computing Era: Enhanced Signal Propagation Models and Algorithm Selector for Providing Location Estimation Services within Cellular Radio Networks - Tapa blanda

Sinopsis

Mobile location estimation has received considerable attention over the past few years due to its great potential in providing support to different kinds of location-based services. As the cost of the mobile computing devices decreases, many people own one or more mobile computing devices for different usages. These factors make ubiquitous computing possible and bring it into a new era of computing. Generally, user¿s location is one of the most important information for ubiquitous computing. It enables location-aware services and therefore makes ubiquitous computing both practical and useful. In this book, we design a geometric model and a probabilistic model to provide locations for different applications, and then we propose a selector to combine the merits of the above two models to enhance the performance. Our models and algorithms are based on the common attribute of all cellular radio networks---the Received Signal Strength. So our proposed models and algorithms can be applied to all kinds of cellular radio networks. It is a book for academic research and industrial reference.
