Real time IoT mobile anchor nodes outdoor localization mechanism

Recently, most outdoor localizations use a hybrid mechanism that integrating some IoT devices occupying with GPS (Anchor Nodes) and other wireless sensor nodes like LoRaWAN (without GPS-Unknown node). This hybrid method employed to achieve low power consumption and low cost solution. Our proposed framework focuses on determining the Mobile Anchor node locations with high accuracy to enhance the overall accuracy of all IoT nodes. To achieve this goal, the installation of low power consummations and low-cost localization sensors modules will be used in the proposed Anchor IoT node. These modules are the inertial measuring unit (IMU) and the low cost Global Positioning System (GPS). Then, this method will be implemented on AVR microcontroller (ATMega 128) to develop an IoT enhanced localization unit. The achieved results for our proposal show how the IoT device's state can be known accurately and at a high update rate (100 Hz, 10 milliseconds).
