Local Positioning in ANGEPS System:3-D GPS-Free Positioning Method in One-Hop Ad Hoc Networks

本文提出了一个自组网中GPS free的三维定位系统ANGEPS ,阐述了ANGEPS的系统结构和其中单跳范围内的局部定位 .在给定的物理模型下 ,文中提出了局部三维坐标系的建立与定位算法 ,并在数学上加以描述和证明 ,在ns 2模拟器上进行了实验模拟 .模拟结果验证了局部定位方法的有效性 .

GPS sometimes can not be used in positioning of ad hoc networks due to limits of landform or special applications. For such situations, we propose a GPS-free position system ANGEPS (Ad hoc Networks Gps-free 3d Position System). ANGEPS's architecture and local positioning method are described in detail. Under given physical models, a local 3d coordinate system building and positioning approach is introduced and proved mathematically. Simulation results by ns-2 simulator prove that our method is effective.
