The adoption of IoT technologies has accelerated across industries such as healthcare, industrial automation, automotive electronics, and smart infrastructure. Connected devices now play a direct role in decision-making, automation, and real-time monitoring. However, as IoT systems become more pervasive, they also become more exposed to security threats.  In many IoT deployments, communication channels remain the weakest link.

They built a brilliant device. It passed every lab test. The demo wowed investors. The launch went live. However, within weeks, complaints began to pour in that devices froze, batteries drained, and unexpected shutdowns occurred in critical scenarios. The culprit? Firmware instability during power fluctuations in real-world environments. What worked perfectly in a controlled lab setting often cannot survive in
