Abstract:
The traditional methods of detecting ships entail the use of radars or
satellites which are very expensive. In addition of the high cost, satellite
images are easily affected by cloud cover, and it is difficult to identify small
boats or ships on the sea with marine radar due to the noise or clutter
generated by the rough sea surface. Besides, to cover such a big area is no
easy task. Trespasser usually travels in small big, which is nimble and can
travel fast. The time for a law enforcer to respond to the unapproved
presence in the area must be put to as minimum as possible. The other
obstacle is to pinpoint the exact position of the intruder. Because of that,
there are studies made especially to focus on assembling a system using the
accelerometer and also investigate the performance of accelerometer as a
sensor. The sensor will be implemented inside buoys, placed in multiple and
strategic places covering the area of the exposed island. Terrestrial intrusion
detection with Wireless Sensor Networks(WSN), deploy accelerometer and
acoustic sensors in monitored areas to precisely detect the presence of
intruders. Though such networks may work well on the land, it is challenging
to deploy these sensors on the sea surface for ship detection. Connectivity
between the buoy, the condition of the sea, the speed of the wind and
attendance of animal passing the enclosure formed by the buoy can
manipulate the signal interpreted by the sensors. The signal received by the
sensor will be compared with the signal received by the user.
