Independent Sets in random geometric graphs I was wondering if a lot is known about independent sets in Random Geometric graphs? Most google searches don't bring up much. In addition I'm interested in any algorithms used for finding independent sets in Random Geometric Graphs. 
 A: Unit disk graphs are a special type of random geometric graphs, where two of the given nodes on a plane share an edge if their Euclidean distance is less or equal to one. This class has been studied quite a lot and it is probably a good starting point for you. I'm not an expert, but here is a list of paper (and references therein) where I would start from (in chronological order).
