Accurate indoor localization has the capability to convert
the manner people navigate interior in a comparable way that GPS transformed
the way humans navigate exterior. during the last 15 years, several indoor
localization technology were proposed and experimented by way of each academia
and industry. a first-rate hassle is that the proposed answers are evaluated in
distinctive situations, which makes tough any comparison of their performance.
The Microsoft Indoor Localization competition objectives to
convey together actual-time or near actual-time indoor location technology and
examine their overall performance in the same space, fixing the hassle of
absence of a commonplace surroundings to examine indoor localization
technologies. The opposition, now on the 1/3 edition, happened in Vienna,
Austria, on Sunday, April
10th, and Monday April 11th, 2016.
The assessment surroundings changed into very difficult, spanning two floors
with metallic, with a total assessment area of about 500 m^2.
All submissions have been categorized into two categories:
3-D and 2nd localization. All groups within the 3-d localization category had
been required to deploy custom designed hardware, and provide three-D places in
the course of the evaluation. All teams in the 2nd localization class did no
longer require custom designed hardware (just commercial Off-The-Shelf devices) and suggested 2d locations in the
course of evaluation. throughout the first day the groups had been given 7
hours to setup and calibrate their systems and in the course of the second day
each team supplied the coordinates of 15 take a look at points with known
ground truth. at the quit, the evaluation metric turned into the common
localization error across these 15 check points.
A crew of researchers from the Pervasive wireless system
institution led via Dr. Domenico Giustiniano from IMDEA Networks Institute
competed with an answer inside the second category. on the quit of the
opposition, the group of researchers from IMDEA Networks performed a median
error of three.17 meters, which ended in ranking fifth out of ten groups in the
final. (Out of the fifteen groups that were first of all represented on the
competition in the 2d category, simplest ten made it to the very last ranking).
The notion supplied on the Microsoft Indoor Localization
competition via IMDEA Networks researchers runs on commodity wi-fi hardware,
works using wi-fi get admission to factors (APs) and measuring the
Time-of-Flight (ToF) of 802.eleven facts frames to cell devices. The proposed
solution turned into the best one which did now not require any customized
software program within the mobile tool, neither inputs from inertial sensors
within the mobile device. The cell tool really needed to be related to the
commercial Off-The-Shelf wi-fi get entry to factors with customized firmware
operating inside the center of the 802.11 MAC kingdom device of a low-cost
wireless chipset (price of the chipset in keeping with unit of much less than 3
dollars).
The IMDEA Networks answer is the simplest available these
days to rapidly construct a positioning machine in a brand new indoor
environment with commodity hardware. It solves the following three traditional
problems supplied with the aid of different indoor location technology: (i)
large and pricey guide on-website online calibration; (ii) installation of a
committed software on cellular devices while this isn't always necessary; and
(iii) quicker depletion of the battery of the cell device due to the inertial
sensors and running software program.
The IMDEA Networks solution estimates the location of
802.eleven widespread-well suited devices, including smartphones, with distance
from each AP to mobile targets envisioned with ToF ranging measurements and
based totally on an adaptive environmental education algorithm. a few details
may be located within the 1/3 reference provided beneath.
