You might wan't to state what you want tips about and what area? LOD can be simple to quite complicated depending on many factors.

I created a simple terrain LOD system for Irrlicht. I just calculate "weight" for each node in heightmap. The "weight" depends upon difference of heightmap value and interpolated value between surrounding nodes. After this it is quite easy to calculate which nodes are skipped in LOD optimization.
