The continuing human-elephant conflict in Sri Lanka has resulted in loss of human as well as elephant lives. Detecting and localizing elephants is an essential component of any viable solution to this problem. Currently, we conduct feasibility tests on using low cost sensors to detect elephants from a long distance, leveraging the infra-sounds emitted by them. In this paper we present the test environment that we have set up for this purpose and some preliminary, but promising results.

Eloc: Locating Wild Elephants Using Low-Cost Infrasonic Detectors

This paper presents Eloc, a system that detects the presence of elephants using their infrasonic emissions near human habitats and then localize their positions, and presents promising results in localizing an artificialinfrasonic source and real-world experiments that suggest that this system can localize free ranging elephants in the wild using this low cost infRasonic detector.

Poster: A Low-cost Elephant Localization System

The design and preliminary results of the elephant localization system that is based on infrasonic emissions from wild elephants are presented, which aims to identify the presence of wild elephants around human habitats.

Automated virtual elephant fence based on detection, alarming, and coordinated redirection of wild elephants

The present study involved in-depth experimentation to investigate the effects of multiple stimuli on real elephants based on the known elephant responses to such stimuli and may lay a foundation for a novel approach toward the management of human-elephant conflict and elephant-train collisions.

Current and Future Approaches to Mitigate Conflict between Humans and Asian Elephants: The Potential Use of Aversive Geofencing Devices

It is recommended that the efficacy and welfare impact of AGDs be evaluated using captive elephants along with public perception of using AGDs on elephants as a means of addressing the inherent deficiencies of common HEC mitigation tools.

The IoT based embedded system for the detection and discrimination of animals to avoid human-wildlife conflict

An early warning message which contains an animal type, age, elephant SOM, global positioning system (GPS) tracks its location information and all this information will be transmitted via global system for mobile communication (GSM) to the forest authorities, local communities, radio station or local channels indicating that an animal movement is near to forest border areas.
