The ubiquitous computing scenario brings many new problems such as coping with the limited processing power of mobile devices, frequent disconnections, the migration of code and tasks between heterogeneous devices, and others. Current practical approaches to the ubiquitous computing problem usually rely upon traditional computing paradigms conceived back when distributed applications where not a concern. In this paper we propose UbiHolo, a new end-to-end model oriented to development and execution of applications over large- scale ubiquitous computing systems. UbiHolo is based on the Holoparadigm (in short, Holo), a new software paradigm oriented to the development of distributed computer systems. After that we show that UbiHolo is scalable, and that it is possible to create and manage execution of applications over large-scale ubiquitous environments without a great impact on application 's user response tunes. Our results are obtained through a simulation of a Holo system with up to 950 nodes, which was implemented over the p2psim simulator.
