AOA-Assisted TDOA Localization Based on Improved Whale Optimization Algorithm for Asynchronous Wireless System Networks

This paper proposes a AOA-assisted TDOA localization method based on an improved whale optimization algorithm (IWOA) combining TDOA and AOA for asynchronous wireless sensor networks (WSNs). A TDOA compensation scheme is first introduced to address network asynchrony. This scheme uses the communication timestamps betwee...

Geometry-Graded ESKF UWB/IMU Tracking Algorithm With Base-Station Optimization for Hybrid LoS/NLoS Environments

With the advancement of Internet of Things (IoT) technologies, the demand for accurate indoor positioning is increasing. Existing methods perform well in line-of-sight (LoS) conditions but suffer in non-line-of-sight (NLoS) conditions due to signal reflections and obstructions. To address this challenge, this paper pre...
