In this paper, we introduce an unified ubiquitous middleware which supports an infrastructure to provide the ubiquitous convergence services by providing not only dynamic service discovery based on context-awareness but also variety of converged services in three applications such as environment management, traffic accident management and underground fire accident management. It is composed of three layers which support the unified efficient ubiquitous computing: context-aware computing layer(framework), ubiquitous core computing layer (framework), common interface layer(framework). Therefore, It has the multilayered architecture which makes applications or services used everywhere by providing the cooperative interacting computing environment among the layers. It can provide modularity and expansibility through the design of multi-hierarchical structure, and reduces complicatedness of the system and increases reusability and flexibility of components.
