Evaluating Precision of a new Hybrid Indoor Localization System

Bluetooth Low Energy (BLE) has revealed for decades many interesting opportunities especially in the field of positioning that made of it one of the most used technologies in indoor localization solutions. The system we propose is a combination of BLE, Acoustic and LiFi technologies. Our approach is not just arithmetic but using real time computed metrics that act precision indicators or "Dilution of precision" (DOP) weights of the results given by each technology. Depending on these DOP-like indicators, we were able to judge how much precise and accurate the returned results are. Our new approach was confirmed during experiments showing that the precision of this new hybrid system is much better when using these new precision metrics.
