Ubiquitous network applications are generally designed for a whole network. This notion should be reflected in the way a network is programmed. We believe that providing abstractions and support that allow the programming of the network as a whole is a step into the right direction.
The proposed top-down approach is suitable for heterogeneous networks. This approach does not require all nodes to have the same common communication protocols. We still require them to be able to communicate with each other. However, we do not build applications on top of certain common layers.
By automating the translation process the application developer does not have to deal with communication, synchronization or other low-level optimisation problems which make distributed applications complex and error-prone
