On the Dynamic RSS Feedbacks of Indoor Fingerprinting Databases for Localization Reliability Improvement
Location data is one of the most widely used context data types in context-aware and ubiquitous computing applications. To support locating applications in indoor environments, numerous systems with different deployment costs and positioning accuracies have been developed over the past decade. One u...
