No. There are many layer 3 protocols, and some layer 4 protocols  
built on top of them. For example, TinyOS 1.x, Boomerang, and TinyOS  
2.0 all have different collection tree protocols (layer 3). TinyOS  
1.x has two: MintRoute and MultihopLQI. The latter is generally more  
efficient than the former, but only works on nodes with a CC2420  
radio (telos, micaz). Boomerang has a slightly modified version of  
MultihopLQI. TinyOS 2.x has  CTP (the Collection Tree Protocol),  
which is specified in TEP 123.

You find the same diversity in dissemination, etc.

TinyOS 1.x, Boomerang, and TinyOS 2.x all work on telos nodes.  
Boomerang only supports the Motiv variant of the telos revision B,  
the TMote. TinyOS 1.x and 2.x support the telos rev. B and telos rev A.
