Specification of Sensing Coverage Zones in Two‐Dimensional Acoustic Target Localization
International Journal of Distributed Sensor Networks, Volume 2025, Issue 1, 2025.Target localization (positioning) by the time difference of arrival (TDoA) using previously localized wireless sensor nodes has wide applications. Three‐degree sensing coverage cannot calculate accurate spatial‐temporal information of the target object in two‐dimensional acoustic positioning.

Improvement of Ultrasound-Based Localization System Using Sine Wave Detector and CAN Network
Journal of Sensor and Actuator Networks, 2017 This paper presents an improved indoor localization system based on radio frequency (RF) and ultrasonic signals, which we named the SNSH system. This system is composed of a transmitter mounted in a mobile target and a series of receiver nodes that are ...

Assessing the geographic resolution of exhaustive tabulation for geolocating Internet hosts [PDF]
, 2008 peer reviewedGeolocation of Internet hosts relies mainly on exhaustive tabulation techniques. Those techniques consist in building a database, that keeps the mapping between IP blocks and a geographic location. Relying on a single location for a whole

IET Wireless Sensor Systems, Volume 14, Issue 6, Page 427-440, December 2024.The authors present APOTSA, a novel algorithm for optimising anchor placement in indoor localisation systems, aiming to improve accuracy and reduce execution time. The approach APOTSA applies the Tabu search algorithm to minimise the expected residence area for better localisation.

Not afraid of the big bad wolf: calls from large predators do not silence mesopredators
Wildlife Biology, Volume 2024, Issue 6, November 2024.Large predators are known to shape the behavior and ecology of sympatric predators via conflict and competition, with mesopredators thought to avoid large predators, while dogs suppress predator activity and act as guardians of human property. However, interspecific communication between predators has not been well‐explored and this assumption of ...
