Abstract EN

The development of the Internet of Things has accelerated research in the indoor location fingerprinting technique, which provides value-added localization services for existing WLAN infrastructures without the need for any specialized hardware.

The deployment of a fingerprinting based localization system requires an extremely large amount of measurements on received signal strength information to generate a location fingerprint database.

Nonetheless, this requirement can rarely be satisfied in most indoor environments.

In this paper, we target one but common situation when the collected measurements on received signal strength information are insufficient, and show limitations of existing location fingerprinting methods in dealing with inadequate location fingerprints.

We also introduce a novel method to reduce noise in measuring the received signal strength based on the maximum likelihood estimation, and compute locations from inadequate location fingerprints by using the stochastic gradient descent algorithm.

Our experiment results show that our proposed method can achieve better localization performance even when only a small quantity of RSS measurements is available.

Especially when the number of observations at each location is small, our proposed method has evident superiority in localization accuracy.
