Wildlife conservation and rail track monitoring using wireless sensor networks

In this paper we put forward an approach, first of its kind, to collectively address conservation of elephants by preventing their death being overrun by trains and monitoring the integrity of the rail track. It utilizes a unique method for deterring the elephants using infrasonic sound from crossing the rail track. For obtaining this output the sensing devices are placed in proximity areas of the rail track using a novel passive node mobility mechanism. These devices act as an input to the actual sensing nodes, that would emit the infrasonic sound. Utilizing a novel two - cycle communication and sensing check the integrity of the rail track is evaluated and the result is informed to the regional base station (RBS). The proposed approach offers a promising solution to the two issues, subject to field evaluation and validation.
