Dew computing is a distributed computing paradigm that leverages the underutilized resources (computation, storage, networking) of geographically proximate end devices, such as personal computers, smartphones, and smart devices. It investigates architectures and methodologies for orchestrating these local resources to execute micro-tasks and provide services, typically as a complementary layer operating below or alongside edge and cloud computing infrastructure, aiming to enhance application performance, reduce latency, and improve system resilience by keeping processing and data closer to the user.
