Tao Huang, Zhikui Chen, Feng Xia, Cheng Jin, Liang Li

摘要:

许多定位算法和系统已经开发出了无线传感器网络的室内和室外环境。现有的定位算法为了获得更高的定位精度,往往需要额外的硬件设备,这不仅增加了成本,而且极大地限制了定位应用的范围。在本文中,我们提出了一种方法,可以有效地满足不同的定位精度要求的大多数室内和室外的定位服务在实际应用中。我们的算法是由两个阶段组成:分区阶段,其中目标区域被分割成小网格和定位细化阶段,其中可以通过应用技巧算法生成一个更高精度的位置。一个实际的演示系统,使用我们的算法已经开发,以说明其可行性和有效性。实验结果表明,该算法能够提高定位精度.

英文摘要:

Many localization algorithms and systems have been developed by means of wireless sensor networks for both indoor and outdoor environments. To achieve higher localization accuracy, extra hardware equipments are utilized by most of the existing localization algorithms, which increase the cost and greatly limit the range of location-based applications. In this paper we present a method which can effectively meet different localization accuracy requirements of most indoor and outdoor location services in realistic applications. Our algorithm is composed of two phases: partition phase, in which the target region is split into small grids and localization refinement phase in which a higher accuracy location can be generated by applying a trick algorithm. A realistic demo system using our algorithm has been developed to illustrate its feasibility and availability. The results show that our algorithm can improve the localization accuracy.
