DEVELOPMENT OF COASTAL GUIDE SYSTEM USING SMART BUOY APPROACH

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.
