The fingerprinting technique based on received signal strength (RSS) has been intensively researched for indoor localization in the last decade. Instead of using discrete reference points to build fingerprint database, this paper applies the surface fitting technique to construct RSS spatial distribution functions and proposes two location search methods to find the target location. We also propose...
In the past, indoor wireless access systems had been designed mainly from the radio coverage perspective. Recently, fingerprint-based localization has also been proposed as another popular application for such access systems. However, few has been studied in the network design for both coverage and localization at the same time. This paper proposes a novel network design for guaranteeing radio coverage...
Indoor localization has become a hot topic thanks to the fast development of wireless local area networks. The basic localization scheme can be divided into two approaches: fingerprint-based and lateration-based. In this paper, we propose a novel localization method that combines the fingerprint method and lateration method. Fingerprint-based method is first used for sub area determination and lateration...
