Special Issue Information

Dear Colleagues,

The first iPhone was released over a decade ago, triggering the smart-device revolution and placing powerful communication, computing, and sensing devices in our hands. Leveraging the multi-dimensional capabilities of smart devices has paved the way for a new generation of highly personalized and context-aware services. A fundamental building block, indoor localization has emerged as a major scientific and technological challenge. The solution space has grown richer over time, to include a variety of underlying sensor technologies – RF, IMU, acoustic, etc. – as mobile computing devices have evolved to include smartphones, tablets, RFID tags, wearables, and even micro-implants.

This Special Issue will bring together the latest research that leverages the multitude of sensors to address indoor localization challenges across the universe of smart devices and objects. This includes automatic indoor mapping, positioning, navigation, and tracking. There will be an emphasis on articles that introducing novel ideas and algorithms coupled with clever engineering using real-life prototype implementations and evaluations.

Topics of interests include, but are not limited to, the following:

  • Sensor fusion algorithms and implementations
  • Applications of machine learning to indoor localization
  • Localization and Internet of Things
  • Emerging localization and sensor-based applications
  • Emerging sensors for indoor localization
  • 3D localization
  • Localization of battery-free devices
  • In-body localization

At least four non-coplanar anchor nodes (ANs) are required for the time-of-arrival (ToA)-based three-dimensional (3D) positioning to enable unique position estimation. Direct method (DM) and particle filter (PF) algorithms were developed to address the three-anchor ToA-based 3D positioning problem. The proposed DM reduces this problem to the solution of a quadratic equation, exploiting the knowledge about the workspace, to first estimate the x- or z-coordinate, and then the remaining two coordinates. The implemented PF uses 1000 particles to represent the posterior probability density function (PDF) of the AN’s 3D position. The prediction step generates new particles by a resampling procedure. The ToA measurements determine the importance of these particles to enable updating the posterior PDF and estimating the 3D position of the AN. Simulation results corroborate the viability of the developed DM and PF algorithms, in terms of accuracy and computational cost, in the pursuit and circumnavigation scenarios, and even with a horizontally coplanar arrangement of the three ANs. Therefore, it is possible to enable applications requiring real-time positioning, such as unmanned aerial vehicle (UAV) autonomous docking and circling a stationary (or moving) position, without the need for an excessive number of ANs.
