Use of Negative Information in Positioning Algorithms

摘要

Wireless communication networks exploit positioning information to deliver personalized, context-aware services. On the other side, positioning information can improve the network performance through location aware routing, coverage management, enhanced security, power saving etc. Availability of position information strongly depends on existing infrastructure, such as cellular base stations and GPS satellites. In order to enhance the performance of indoor localization systems, where infrastructure is not available, the innovative solution presented in this paper considers also the negative information.
