Design Principles

"Leverage inherent configurability of COTS components to achieve application-specific performance targets."

Designers often face constraints with generic COTS components. Understanding how to leverage and optimize the inherent flexibility of these components is crucial for achieving specific performance goals without resorting to custom hardware. This approach can significantly reduce development time and cost while improving the effectiveness of deployed systems.

Quick Cite

Paragraph starter

The selection of commercial off-the-shelf (COTS) wireless sensor nodes presents a challenge in meeting specific application requirements due to their generic design. However, as highlighted by research such as Munir and Gordon (2010), these nodes often possess tunable parameters (e.g., processor speed, sensing frequency) that can be optimized. This optimization allows for specialization, enabling designers to better balance competing demands like extended operational lifetime and rapid responsiveness, thereby enhancing the suitability of COTS components for targeted design projects.
