Evaluation of architectures and strategies for tracking mobile devices in UWB networks

Ultra wide-band radio technology is a good candidate for the development of indoor location & tracking networks. Some interesting application scenarios include relatively large and crowded areas such as shopping malls, but the application of short range UWB in these scenarios has to face different challenges, resulting in a trade-off between the positioning error and the amount of resources needed for location. In order to face these challenges, different system architectures and strategies for the acquisition and distribution of location information can be implemented. In order to assess the performance of the different alternatives in terms of accuracy and resources used for location, a simulation tool has been specifically developed, and the main results obtained are presented.
