Abstract

Localization information of individual nodes is crucial for many advanced functions including routing, querying in wireless sensor networks. Most of the existing localization algorithms in wireless sensor networks are designed for outdoor environment and few of them can get a reasonable localization precision in indoor environment. This paper presents a novel indoor localization scheme which uses the spatial connective information to filter distorted messages, so as to improve the positioning precision. We establish an indoor positioning dome system, make performance comparison with other schemes and fully prove the advantages of our proposed indoor scheme.
