Wi-alert : a wireless sensor network based intrusion alert prototype for HEC

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
