Current trends in mobile services envisage location-based networking as a major strong stimulator for the development of novel solutions for obtaining positioning information in wireless networks. This book discusses mobile positioning solutions applied on top of current wireless communication networks. Moreover, it introduces advanced and novel topics such as localization in heterogeneous and cooperative scenarios. In this fully updated second edition, the authors summarize recent developments in mobile positioning and tracking. Compared with the previous version, the new edition introduces more advanced topics, providing the bridge between research and industry. It works as an important reference and provides good foundations for new researchers.
