Modular design

Definition

Modular design is an approach that breaks down a system into smaller, manageable, and interchangeable components or modules. This design philosophy allows for flexibility and scalability, enabling easier upgrades, maintenance, and integration of new technologies, particularly in hardware platforms used in wireless sensor networks.

5 Must Know Facts For Your Next Test

1. Modular design promotes ease of replacement and repair, allowing for individual components to be swapped out without the need for a complete system overhaul.
2. In wireless sensor networks, modular design supports the integration of various sensors and communication technologies, enhancing the overall system's functionality.
3. This design philosophy often results in cost savings over time due to reduced downtime and the ability to upgrade only specific modules instead of entire systems.
4. Hardware platforms like MICAz, TelosB, and Arduino exemplify modular design by providing standardized interfaces that allow developers to create custom solutions by mixing and matching components.
5. Modular design encourages innovation as new modules can be developed and tested independently, fostering rapid prototyping and experimentation.
