A Review Paper of the Indoor Location Determination Approaches and Techniques
By increasing the number of mobile devices, the demand for context aware applications are rising faster than ever. Context aware applications are referred to the mobile applications which are aware of their environment and can react to it. These applications show their benefits when it comes to delivering detailed information based on the users’ surroundings. The locating and tracking of users becomes more challenging in areas without the coverage of GPS (Global Positioning System) signal such as indoor environment and the areas under protection of GPS jammers. In such areas, to overcome the deficiency of GPS signal, technologies such as ultrasound, ultra-wide band, infra-red and wireless signal are being utilized. This Paper aims to review the techniques and factors related to the location determination.
