The Internet of Things (IoT) is rapidly expanding, including in conflict zones where security is
critical. Sound signals used for intelligence in the Middle East, combined with Sahel challenges from poor
infrastructure, emphasize the need for better data collection. This paper proposes a secure IoT architecture
using Low Power Wide Area Network (LPWAN) technology and steganography to efficiently optimize sharing
of critical information and enhance military operational efficiency. Based on surveys with military personnel
and reviews of existing IoT methods, our solution leverages LPWAN’s range, low energy, and cost benefits to
address security and resilience challenges in high-risk regions globally.
