From missions to systems

Barry Porter, Alan Dearle, Simon Dobson
2012 Proceedings of the 7th International Workshop on Middleware Tools, Services and Run-Time Support for Sensor Networks - MidSens '12  
Specifically, we argue that a computational model is needed in which the ways that data flows through networks, and the ways in which decisions are made based on that data, is transparently distributable  ...  While this remains true in selected cases, the majority of future sensor network applications will demand much more intelligent use of their resources as networks increase in scale and support multiple  ...  a taxonomy built around the notions of control flow and data flow.  ...
