Bayesian Fusion for Indoor Positioning Using Bluetooth Fingerprints
This paper studies the use of received signal strength indicators (RSSI) applied to fingerprinting method in a Bluetooth network for indoor positioning. A Bayesian fusion (BF) method is proposed to combine the statistical information from the RSSI measurements and the prior information from a motion model. Indoor field tests are carried out to verify the effectiveness of the method. Test result...

In this paper, we present a self sufficient and distributed localization algorithm for wireless sensor networks that does not require any external infrastructure support to estimate sensor node coordinates. Our algorithm uses measured inter-node distances and localizes the entire network in a local coordinate system upto a global translation, rotation and reflection. Using TOSSIM simulations, w...

The performance of Ultra-Wideband (UWB) indoor positioning systems based on Time of Arrival (TOA) techniques is generally affected by the density of reference points (RPs), as well as undetected direct path (UDP) conditions. For a fixed number of reference points (RPs), the performance of some indoor positioning algorithms tends to degrade as the size of the area is increased, i.e. the RP densi...
متن کاملIndoor Non-directed Optical Wireless Communications - Optimization of the Lambertian Order
For an indoor non-directed line of sight optical wireless communication (NLOS-OWC) system we investigate the optimized Lambertian order (OLO) of light-emitting diodes (LEDs). We firstly derive an expression for the OLO from a conventional Lambertian LED model. Then, we analyze the indoor multi-cell NLOS-OWC channel characteristics including the optical power distribution and the multipath time ...
