We propose an adaptive localization and channel state information (CSI) estimation model using the distance vector for indoor multiple-input multiple-output (MIMO) visible light communication (VLC). Under normal conditions, receivers (Rxs) require the CSI of all channels [formed by multiple transmitters (Txs) and multiple Rxs] to recover the original data, and the received signal strength (RSS) obtained from Txs, i.e., light-emitting diodes (LEDs) to predict the Rx’s location. A beacon [or pi...

In this paper, we proposes a trilateration-based positioning model for constructing a real-time 2D map for wireless sensor network, that is help users real-time tracking the sensor node via an application without the use of the Global Positioning System (GPS) module equipped on the sensor node. For building up the system, there are three anchor nodes whose locations are known, the receiver based on the received signal strengths (RSS) sending from three anchor nodes estimates its location and ...
