Intelligent Rf-Based Indoor Localization Through Rssi Using Lora Communication Technology : This thesis has proposed indoor localization approaches. where the increase in ubiquitous computing and context-dependent have led to an emphasis on a continuous search for promising localization technologies and techniques. Typical RF-Based localization technologies such as Cellular, RFID, Bluetooth, Wi-Fi, Zigbee, and UWB have been widespread studied over the past decades. Recently, LoRa communication technology has been suggested as a potential alternative to those of exiting wireless communication standards with low power consumption and low implementation costs. This thesis therefore presents an indoor localization technique through the use of Received Signal Strength Indicator (RSSI) of LoRa Technology. The LoRa chip from SEMTECH utilized on a compact board with built-in antenna. The Arduino microcontroller employed as a core processor with a step-down switching regulator. Five sets of LoRa nodes were implemented and four of which were utilized as static nodes, radiating a signal power from 5-meter high from the floor. The receiving node placed in a particular coordinate on the floor. The Received Signal Strength values were employed as inputs for Artificial Neural Network (ANN) for estimation of the coordination of the receiving node. The accuracy was approximately 95%. The results provide satisfactory accuracy and low-power operation as for an alternative for large scales deployments of indoor localization.
