Thanks for the reply. Actually we haven't experienced anything yet, not that I know of. I'm just the ndn-guy of the team, who is encouraging his colleagues to consider NDN for implementing their WSN scenario(I guess the reason why I'm here, is clear now:). My teammate will show up soon. She probably knows about the micro-controller specs. But in my humble assumption, it should be a kind of Arduino-based ones.
The sensors which are used in Anil's suggested paper are ATxmega128A1 microcontrollers.
What about the caching? In some star-like topologies most(if not all) of the sensors are not intermediate, and don't need content store, thus there is no need to check it, right? So why bother?
Thank you so much. I will take a full look at that. Maybe we should consider some CCN-NDN differences then.

You may want to take a look at this optimized ccn stack for WSN. I don't
know however what footprint it works on.
