Joint Vehicle Tracking and RSU Selection for V2I Communications with Extended Kalman Filter
Jiho Song, Seong-Hwan Hyun, Jong-Ho Lee +2
We develop joint vehicle tracking and road side unit (RSU) selection algorithms suitable for vehicle-to-infrastructure (V2I) communications. We first design an analytical framework…
Sensor-Aided Learning for Wi-Fi Positioning with Beacon Channel State Information
Jeongsik Choi
Because each indoor site has its own radio propagation characteristics, a site survey process is essential to optimize a Wi-Fi ranging strategy for range-based positioning solution…
Calibration-Free Positioning Technique Using Wi-Fi Ranging and Built-in Sensors of Mobile Devices
Jeongsik Choi, Yang-Seok Choi
As positioning solutions integrate multiple components to improve accuracy, the number of parameters that require calibration has increased. This paper studies a calibration-free p…
Unsupervised Learning Technique to Obtain the Coordinates of Wi-Fi Access Points
Jeongsik Choi, Yang-Seok Choi, Shilpa Talwar
Given that the accuracy of range-based positioning techniques generally increases with the number of available anchor nodes, it is important to secure more of these nodes. To this…
Deep Learning Based NLOS Identification with Commodity WLAN Devices
Jeong-Sik Choi, Woong-Hee Lee, Jae-Hyun Lee +2
Identifying line-of-sight (LOS) and non-LOS (NLOS) channel conditions can improve the performance of many wireless applications, such as signal strength-based localization algorith…
