Ubiquitous computing embeds computer technology in our everyday environment, providing a human with information services and applications through any device over different kinds of networks. Ubiquitous computing can be seen as a prerequisite for pervasive computing that emphasizes mobile data access and the mechanisms needed for supporting a community of nomadic users. Ubiquitous software is the software required in ubiquitous computing environments. This paper surveys the challenges and state-of-the-art software technologies applicable to ubiquitous computing environments. Ubiquitous wireless world systems trigger a set of requirements, e.g. interoperability, adaptability and mobility, for ubiquitous system and software technologies. The main challenges of ubiquitous software are a uniform and adaptive middleware technology, iteroperability of services and networks, and the enabling technologies required in their development. Futhermore guaranteeing secure transactions between service providers, content providers and users is essential in worldwide pervasive computing environments. Although standards, reference architectures and generic software technologies provide the basis for future ubiquitous software development, new kinds of micro architectures and software technologies, and development methods are needed.
