The remote sensors I am interested in are *not* connected to the
internet.  They are connected via radio to each other and to base
stations, and the base stations may then be connected to the
internet (probably using an OS and IP stack written in C).

There is a serious point here that *end* devices are likely to be
as small as you can get away with.  Instead of spending money on
bigger/faster machines, it's rather more useful to have *more*
machines that are just capable enough to do the job.

Other people may be interested in other things.
