无线传感器网络协作节点船舶位置检测

Ship Location Detection of Cooperative Nodes in Wireless Sensor Networks

为了对船舶进行实时监控,可以通过收集船舶的信息(例如速度和位置)来进行。然而,非法船舶通常会关闭自动识别系统(AIS)信号,所以其速度和位置信息很难采集。海上雷达和卫星云图虽然是现在普遍使用的监测方法,但成本过高,并且也有自身的监测缺陷,论文提出利用无线传感器网络(WSN)进行船舶位置检测,这是一种简单易行且廉价的方式。假设每个传感器节点都装有全球定位系统(GPS),论文通过使用四个协作的传感器节点监测船舶所产生的波浪,从而推导出了一种新的计算船舶位置的公式。该公式能够在三个不同的方向定位船舶的位置,并对船舶定位检测的必要条件进行了量化。

In order to monitor the ship in real time,the information of the ship(such as speed and position)is collected.How ever,unlawful ships usually turn off the Automatic Identification System(AIS)signal,so its speed and location information are dif ficult to collect.Marine radar and satellite cloud images are widely used monitoring methods,but their cost is too high,and they al so have their own monitoring shortcomings.This paper proposes a simple and inexpensive way to use Wireless Sensor Network(WSN)for ship positioning.It is assumed that each sensor node is equipped with a Global Positioning System(GPS),this paper de rives a new formula for calculating ship position by using four coordinated sensor nodes to monitor the waves generated by the ship.This formula can locate the ship's position in three different directions and quantify the necessary conditions for the ship's position ing detection.
