Universal Firmware Upgrade Over-The-Air for IoT Devices with Security

Traditionally, it often caused sporadic disruption and degradation of device performance for upgrading the firmware of the devices remotely. Developers had to go to the field and get back the device, connect it to their computer, upload the new code with changes or corrections and put the device back on the field. This entire process is however very cumbersome and unscalable for organizations. But nowadays a unique way to update connected devices with no interference, remotely and reliably is Over-The-Air firmware update. Our paper aims to highlight on our work in this field where we have created a framework which could be used to upgrade remotely the firmware of various IoT devices.
