Abstract
In the period of wireless communication, Indoor positioning systems (IPSs) are getting enormous attention. These systems are construct to attain location information of individuals and objects inside a building. Now a day all the applicable wireless technologies used in this context are Wi-Fi and Bluetooth Low Energy (BLE) based. These advancements are additionally decided for their ease of use, low cost and integration into wireless devices. However, these techniques are having some positioning errors along with specified region. Here, we introduce another wireless technology named Light Fidelity (Li-Fi), the basic convention of this technology is the transfer of information using light illumination by light emitting diodes. This article primarily established a set of evaluation indexes for the performance of these three Wi-Fi, BLE and Li-Fi technologies in indoor positioning scenarios. We compare the predefined IPSs in term of performance and limitations. After then outline the tradeoffs among these systems from the perspective of all evaluation entities. We show experimentally that Li-Fi technology achieves a high efficiency but for accuracy, Wi-Fi is still better than Li-Fi and BLE technology.
