Light fidelity (LiFi) uses light emitting diodes (LEDs) for high-speed wireless
communications. Since an LED lamp covers a small area, a LiFi system with multiple access …

Due to the influence of indoor signal multipath effect and human disturbance, the indoor
positioning technology of WiFi fingerprint based on deep learning is poor stability. The large …

Visible light communications (VLC) are proposed for increasing the spectral efficiency and
the number of devices served in indoor environments, while providing illumination through …

In this paper we present amount of fading for composite fading channel. For this purpose two
probability density functions have been taken. One is Weibull function and another one is …

Abstract Systems for indoor positioning using radio technologies are largely studied due to
their convenience and the market opportunities they offer. The positioning algorithms …

The increasing importance of location-aware computing and context-dependent information
has led to a growing interest in low-cost indoor positioning with submeter accuracy …

This paper presents a site-specific empirical channel model for large-scale propagation in a
2.4 GHz outdoor wireless network. The received signal strength measurements are taken in …

Nowadays, the use of sensor nodes for the IoT is widespread; nodes that compose these
networks must possess self‐organizing capabilities and communication protocols that …

Many factors influence the positioning performance in WLAN RSSI fingerprinting systems,
and summary of these factors is an important but challenging job. Moreover, impact analysis …
