Abstract: The emergence of the Internet of things (IoT) shaped the future of many domains where connectivity became a hot topic in electronic engineering. Recently, IoT was being a part of Indoor positing systems where devices need to communicate continuously at a defined time slot leading to various problematics for the conventional positioning algorithm. We propose an ESP8266 NodeMCU tracking system of multiple tags using a Wireless communication. The proposed implemented algorithm consists of two-phase in the first stage, a master anchor sends a signal to tags in order to establish the communication. In the second one, the master anchor initiates distance ranging and positioning. This two-phase based system aims to minimize reading time and increase the accuracy of positioning by reducing distance ranging errors, which we validate in our proposed model and algorithm by an experiment in an indoor environment.
