RSSI-Based Smooth Localization for Indoor Environment [PDF]

The Scientific World Journal, 2014
Radio frequency (RF) technique, for its better penetrability over traditional techniques such as infrared or ultrasound, is widely used for indoor localization and tracking. In this paper, three novel measurements, point decision accuracy, path matching error and wrong jumping ratio, are firstly defined to express the localization efficiency.

A NODE LOCATION ALGORITHM BASED ON IMPROVED GRASSHOPPER OPTIMIZATION IN WIRELESS SENSOR NETWORK

ICTACT Journal on Communication Technology, 2022
As the use of swarm intelligence algorithms grows, so does the interest in placing nodes in a Wireless Sensor network. For this reason, the RSSI range model positioning algorithm has been replaced by a more accurate one.

BLE localization using RSSI measurements and iRingLA [PDF]

2015 IEEE International Conference on Industrial Technology (ICIT), 2015
Over the last few years, indoor localization has been a very dynamic research area that has drawn great attention. Many methods have been proposed for indoor positioning as well as navigation services. A big number of them were based on Radio frequency (RF) technology and Radio Signal Strength Indicator (RSSI) for their simplicity of use.

RF source localization using obstacles map and reflections [PDF]

International Journal of Industrial Electronics, Control and Optimization, 2021
In this paper, RF source localization in non-line of sight condition, using map of the obstacles is proposed. Received signal strength indicator (RSSI) and angle of arrival (AOA) measurements are observations which are obtained from received signal on ...

Plasma GFAP and NLRP3 Associate with Cognitive Impairment After Recent Small Subcortical Infarct via Periventricular White Matter Hyperintensity [PDF]

CNS Neurosci Ther
Ischemic stroke, recent small subcortical infarcts, induce systemic inflammation, leading to elevated levels of circulating inflammatory proteins. Through blood–brain barrier disruption, these proteins may gain access to the central nervous system and amplify microvascular injury and white matter degeneration, which directly and indirectly lead to ...

Drone Controller Localization Based on RSSI Ratio

Sensors, 2023
We proposed two methods for the localization of drone controllers based on received signal strength indicator (RSSI) ratios: the RSSI ratio fingerprint method and the model-based RSSI ratio algorithm. To evaluate the performance of our proposed algorithms, we conducted both simulations and field trials. The simulation results show that our two proposed
