摘要:

由于受到地形和特殊应用的限制,GPS在很多情况下不适用于自组网的定位。本文提出了一个自组网中GPS-Free的三维定位系统ANGEPS,并阐述其系统结构和其中的条件泛洪全局定位方法——露珠泛洪法。在给定的物理模型下,提出了露珠泛洪法的工作过程和代价估算,并在数学上加以了描述和证明,给出了系统性能最优的条件。

Abstract:

GPS sometimes can not be used in the positioning of ad hoe networks due to the limits of landform or special applications. For such situations, we propose a GPS-free positioning system ANGEPS and describe its architecture and the conditional flooding global positioning method called dewdrop flooding.   Under given physical models, the work flow and cost estimation dewdrop flooding method is described and proved mathematically. The conditions of optimiz ing the whole system are also given here.
