Abstract:
Animal tracking in sensor network domain is a key area of wireless sensor network
(WSN) applications. To realize the concept, this project is discussed on the use of WSN
to track movements of elephants. This would allow wildlife researchers to understand
the behavior of these elephants. The prototype system consists of moving one node
(collard elephant) with a grid of three fixed base stations. This system employs radio
waves for distance ranging and trilateration approach to localize the collard elephant.
The data obtained is passed on to a web based data server and movement is shown on a
digital map using browser based visualization software, utilizing Google Map
Application Programming Interfaces (API). As the power conservation is critical, and
interconnecting wires are inconvenient for the transmitter in the collar, wireless power
transmission (WPT) concept is going to be applied as a backup power supply to boost
the battery life time. As a further improvement, a pre warning system is implemented as
a house hold application for prone areas of human elephant conflicts.
