摘要
随着无线传感网技术在舰船中的大量使用,其定位功能也正在被充分挖掘。不同于传统的卫星定位技术,无限传感器网络的设备成本非常低廉,且组网迅速,具体功能通过软件编写可以轻松实现。本文在研究船舶定位需求的基础上,提出一种高精度的基于高斯混合模型的无线传感网在线定位模型,建立RSSI三点式定位模型。并在实验室模拟出船舶在海洋中的航行环境,采用Online-LEGMM仿真系统对此算法的定位性能进行验证,实验结果取得预期效果,该算法能够对船舶节点准确定位。
As the wireless sensor network technology in the ship in heavy use,its positioning also being fully tapped. Unlike traditional satellite positioning technology,equipment costs even unlimited sensor network is very low,and the network quickly,the specific functionality through software development can be easily achieved. After studying the article based on the needs of ship location,it presents a highly accurate Gaussian mixture model-based wireless sensor networks online positioning model established RSSI three-point positioning model. And in the laboratory to simulate a ship sailing in the ocean environment using Online-LEGMM positioning performance simulation system of this algorithm to verify results achieved the expected results,the algorithm can accurately locate the ship node.
