Abstract
Indoor localization, as a key enabling technology for Internet of Things (IoT) location-based applications, is one of the primary
services in smart automated systems. It is becoming increasingly important and beneficial in many industrial, commercial and public domains.
This paper proposes an iterative trilateration technique for localization
in indoor IoT environment, as an improvement of baseline trilateration.
In our simulations, the iterative trilateration achieves high localization
coverage with accurate location estimation compared to baseline trilateration. Additionally, our technique was analyzed considering different
parameters like communication range, range error and anchors’ fraction
in three-dimensional (3D) space under scenarios with and without obstacle. The results show that our iterative trilateration technique is almost
resistant to the obstacles in the environment.
