Abstract

With the explosive growth in the number of IoT devices, firmware upgrades have become a critical component for ensuring device security and continuous functional optimization. However, the reliability of data transmission during firmware upgrades directly impacts the success rate of upgrades and the stable operation of devices. This paper focuses on enhancing the reliability of data transmission during IoT device firmware upgrades, proposing an optimized solution based on redundant verification, packet retransmission, and dynamic bandwidth adjustment. This approach effectively reduces transmission error rates and upgrade failure rates. Experimental results show that this solution significantly improves the stability and efficiency of data transmission in complex network environments, providing important assurance for the security and reliability of IoT firmware upgrades.
