Abstract:
A wired fence based intrusion detection and alerting mechanism for boundaries separating wildlife habitats
and human settlements was implemented, particularly as a solution to the Human-Elephant Conflict
(HEC). The objective of the research reported in this paper is to propose and verify an alternative
technique for this wired fence based alerting mechanism to overcome its limitations and to improve its
effectiveness.
This article presents a comprehensive study of alternative solutions with deliberate consideration of the
practical constraints. Wi-Alert is a wireless sensor network based intrusion detection system proposed as
the best alternative solution. This article reports the outcomes of the first two phases of ongoing
developments of Wi-Alert.
The first phase of experiments was conducted to investigate the multi-path effect reduction techniques at
one site. In the next phase, experiments were conducted to verify the ability to detect elephants. The results
obtained via the candidate techniques are compared. Both experiments confirm the feasibility of the
prototype as a non-invasive method to detect elephants.
