We propose a distributed recursive Gaussian process (drGP) regression framework for
building received-signal-strength (RSS) map. The proposed framework adopts independent …

This paper presents a nonlinear location estimation to infer the position of a user holding a
smartphone. We consider a large location with number of grid points, each grid point is …

In large-scale fingerprinting localization systems, fine-grained location estimation and quick
location determination are conflicting concerns. To achieve finer grained localization, we …

In this paper, we discuss a similarity inconsistency phenomenon where the radio signal
strength (RSS) signatures of two neighboring positions are dissimilar due to the RSS …

This paper presents and evaluates a method for simultaneously tracking a target while
localizing the sensor nodes of a passive device-free tracking system. The system uses …

This paper presents an application of the firefly algorithm (FA) to Gaussian process (GP)-
based localization. Partial radio-frequency (RF) signature map is first collected and used to …

Received signal strength (RSS) based location fingerprinting is a powerful wireless
positioning technique. It estimates the target location by consulting a preliminary database …

Location-based applications attract more and more attention in recent years. Examples of
such applications include commercial advertisements, social networking software and …

Recent study presents a fundamental limit of the RSS fingerprinting based indoor
localization. In this paper, we theoretically show that the temporal correlation of the RSS can …

Passive localization is fundamental for many applications such as activity monitoring and
real-time tracking. Existing received signal strength (RSS)-based passive localization …
