1. Ship Detection with Wireless Sensor Networks
Abstract
Intrusion detection on the sea is a critical surveillance problem for harbor protection,
border security, and the protection of commercial facilities, such as oil platforms and fisheries. In
this paper, we present an innovative solution for ship intrusion detection. Equipped with threeaxis accelerometer sensors, we deploy an experimental Wireless Sensor Network (WSN) on the
sea’s surface to detect ships. Using signal processing techniques and cooperative signal
processing, we can detect any passing ships by distinguishing the ship-generated waves from the
ocean waves.
Existing System:
The traditional methods of detecting ships entail the use of radars or satellites which are
very expensive. Besides the high cost, satellite images are easily affected by cloud cover, and it
is difficult to detect small boats or ships on the sea with marine radar due to the noise or clutter
generated by the uneven sea surface. Hence we go for new system.
Proposed System:
In this system, the ship intrusion is going to be detected by placing three axis
accelerometers at the sea surface. The waves which are generated by the ocean and intruder ships
are analyzed by the accelerometer and the signal is processed by the controller. The controller
will transmits the data from the sea-shore section to the monitoring in wireless communication
mode called Zigbee. It’s a communication medium which operates in the frequency range of
2.4GHZ. The accelerometer will distinguish both the signals and sends an individual data to the
controller. The accelerometer and ship status is displayed in LCD.
