Abstract:
Wireless indoor localization is a major
challenging issue for state-of-the-art technologies and
applications which require precise and robust
location information. Many restrictions affect the
performance of the wireless indoor localization, for
instance, intricate building architecture, decorated
appliances inside the building, and inaccessibility and
unavailability of using GPS in indoor environments.
Nowadays, time based indoor localization is
considered as a better and popular research trend for
wireless networks. The major disadvantage of time
based localization techniques is difficulty to attain
precise time synchronization. In this paper, Time-
Difference-of-Arrival (TDoA) based wireless indoor
localization technique is proposed which is based on
an effective hybrid time synchronization approach.
Python programming language is used for simulation
evaluations to highlight the improved localization
performance. By using the robust and effective hybrid
time synchronization, localization accuracy of the
proposed system is considerably high.
