[SensorNetArch] Dumb question: Anyone know a good example of above-MAC protocols

[Jonathan Hui]

If we take the stance where SP will provide a broadcast primitive even 
on TDMA link layers, then the example that Trickle provides is that the 
implementation is *very* simple and remains the same code whether it is 
TDMA or CSMA. Today, Trickle would have to deal with unicasting to all 
nodes under TDMA links and unicast in chronological order of the time 
slots. So part of this is not strict performance, but shows the 
difference in code complexity/reuse.
