Call For Papers


Eight IPIN Competition
off-site Indoor Localization

November 2021, online


IPIN is pleased to announce the eight IPIN 2021 Indoor Localization Competition.
The competition is aimed at bringing together the academic and industrial
research communities for evaluating different approaches and envisioning new
research opportunities for the indoor localization area, where no generally
accepted standards exist yet.

The competition builds on the experience of previous competitions and is based
on the EvAAL framework, ensuring experience, solidity and a well-founded
scientific method. IPIN 2021 Indoor Localization Competition is entirely
off-site. It hosts three different Tracks:

• Track 3: Smartphone (off-site)
• Track 4: Foot-mounted IMU (off-site)
• Track 7: Channel impulse response (off-site)

Competitors calibrate their algorithms in advance using a ground truth reference
database, and compete using new unreferenced data.

Track 3 - Smartphone: A pedestrian walking under realistic conditions in
multi-floor buildings using data provided by a conventional smartphone.

Track 4 - Foot-mounted IMU: A pedestrian carries ULISS (Ubiquituous Localization
with Inertial Sensors and Satellites), a state-of-the-art Inertial Navigation
System producing IMU data, MAG data, PRESSURE data & GNSS data, without the help
of any maps.

Track 7 - Channel impulse response: People with UWB tags move through a
cluttered industrial indoor environment in LOS and NLOS conditions.


The evaluation criteria for the competition, restrictions on the accepted
technologies, technical rules and a description of the benchmarks are detailed
in the technical annexes to this call. Announcements and possible refinements
of the annexes, also based on applicants' comments, will be timely distributed
on the competition discussion mailing list and will
appear on the EvAAL web site (

The organising committee plans to provide a web service for obtaining sensor
readings and submitting position estimates. The purpose is to emulate a causal
process similar to the data flow of an on-site competition: input data can be
read only once and only in sequence, and the timestamp of each submitted
position estimate must be the same of the latest sensor reading.

All the data gathered by the competition committee during the competition,
including data produced by competing systems, will be published after the
competition for the purpose of research and comparison. Winners of the
competition will be announced on the EvAAL and IPIN web sites and on the contest
mailing list. Scientific publishing opportunities will be offered to


A competitor can be any individual or group of individuals working as a single
team, associated to a single or a number of organizations, who applies to
participate in one or several Tracks. Only one team from the same organisation
(laboratory) is allowed to compete in any number of Tracks. Registration to the
competition is included in the registration of at least one team member for the
IPIN 2021 conference, and counts as a single paper or poster published at the
conference. Alternatively, registration to the competition costs 100€ for the
first Track plus 50€ for any additional Track, to be paid when results are
