Let’s talk about k-NN for indoor positioning: Myths and facts in RF-based finge...
Torres-Sospedra, Joaquín; Pendão, Cristiano; Silva, Ivo; Meneses, Filipe; Quezada-Gaibor, Darwin; Montoliu, Raúl; Crivello, Antonino; Barsocchi, PaoloMicrosoft proposed RADAR in 2000, the first indoor positioning system based on Wi-Fi fingerprinting. Since then, the indoor research community has worked not only to improve the base estimator but also on finding an optimal RSS data representation. The long-term objective is to find a positioning system that minimises the mean positioning error. Despite the relevant advances in the last 23 years, a disruptive s...
Off-line evaluation of mobile-centric indoor positioning systems: the experienc...
Torres-Sospedra, Joaquín; Jiménez, Antonio R; Moreira, Adriano; Lungenstrass, Tomás; Lu, Wei-Chung; Knauth, Stefan; Mendoza-Silva, Germán MartínThe development of indoor positioning solutions using smartphones is a growing activity with an enormous potential for everyday life and professional applications. The research activities on this topic concentrate on the development of new positioning solutions that are tested in specific environments under their own evaluation metrics. To explore the real positioning quality of smartphone-based solutions and t...
