A geometric graph is a simple graph *G=(V,E)* with an embedding
of the set *V* in the plane such that the points that
represent *V* are in general position.
A geometric graph is said to be **k-locally Delaunay** (or a
D_{k}-graph)
if for each edge (u,v) \in E there is a disc *d* that contains u and
v
but no other vertex of G that has distance at most *k* (in the graph-theoretical sense) from u or v.
Note that a Delaunay graph is k-locally Delaunay for any *k*.

The study of these graphs was recently motivated by topology control for wireless networks.

In this talk we study the maximum edge complexity of such graphs.
