Abstract
Autonomous monitoring in remote riverine regions of Sri Lanka require
systems that can operate for long periods without human presence or stable
infrastructure. This research work presents a low power VLSI architecture
designed for such conditions through a combination of multimodal sensing, event
driven processing and hardware security. The front-end sensors capture
vibration, acoustic, turbidity and passive infrared signatures that reveal
different forms of environmental disturbance. These signals trigger an event
driven processing core that performs threshold detection, lightweight feature
extraction and simple on chip classification while keeping energy use to a
minimum. Tamper resistance framework layer protects both the device and its
data through enclosure penetration detection, intrusion sensing and secure
boot. Solar based power management and multiple communication pathways support
operation in locations where connectivity and maintenance access are limited.
The architecture responds directly to the realities of difficult terrain,
scarce manpower and the frequent destruction of deployed equipment. It provides
a practical foundation for prototype development, laboratory evaluation and
eventual field deployment in challenging riverine environments. This work
represents the initial system‑level phase of an ongoing research and
development effort.
