Abstract: At the core of the problem of the ubiquitous computing devices is the fact that communication has a reciprocal purpose and means with computing. By virtue of the idea implementing embedded Internet, grid computing and Jini, a software architecture is therefore proposed to be configurable statically and dynamically, together with a software development platform which can configurate and prune the architecture components to run on the purpose-specific systems with their unique resource and function constrained. The architecture intends to solve the contradiction between the diversity of services to be provided by ubiquitous computing devices and the resource limitation of the computers embedded in them, thus implementing the communication and collaborative computing when there is a reciprocal purpose and means of communication with computing among the ubiquitous computing devices.
