Detecting wild elephants via WSN for early warning system

A comprehensive discussion on design of a wireless sensor network to detect elephants as an early warning system which can act as a virtual barrier covering elephant corridors or villages would be presented in this paper. The elephant habitats are being continuously reduced due to increasing population and changes in the land-use patterns. Thus human elephant conflict has been increasing and remains unsolved regardless of various solutions developed. The proposed system is a virtual barrier rather than a physical one. A prototype system to detect elephants and send a warning message to the authorities and the villagers has been implemented. The wireless sensor network (WSN) has been setup as a virtual barrier covering elephant corridors or villages.
