We have all become very accustomed to location-based services making our lives easier. Navigation systems in cars and destination guidance systems for pedestrians in city centers have become part of everyday life. However, people’s daily life also consists of activities that take place indoor: at home, at work, at leisure places like shopping malls and museums and at unknown places during holidays or business trips. In these indoor scenarios, technologies that work well outdoors fail only because the signals of the global navigation satellite systems are too weak to be received inside buildings. This makes it difficult to offer context-aware systems where location is a key feature for software functionality related to social networking, advertising, recommendation systems, or healthcare.
Indoor localization systems offer solutions for the technical aspect of this location estimation problem. The systems differ in many ways: which information sources in terms of sensors, knowledge, hardware, and infrastructure are available? What do the models and algorithms look like? Are different information sources combined? All these aspects influence the current research in this area. One important finding of research in recent years is that information from multiple sensors is needed and must be fused in one way or another.
This Special Issue is dedicated to the goal of offering outstanding papers in the described field of multisensors indoor localization.
