摘要：

Position information of unknown node precisely is a key issue of locating service under pervasive computing environment. The paper proposed and proved space error theorem(SET) according to the analysis of the location error produced during positioning using the polygon positioning method in 3-dimentional space. Based on the foundation, to get higher positioning accuracy, the study on the repeating positioning area of unknown nodes was performed, and the space error convergence theorems(SECT) were deduced by analyzing error region with infinite difference method. The simulation results indicated that the location error convergence theorems could meet the requirement of ubiquitous terminal localization and possess preferable localization precision.
