Abstract
Graphs can be used to model many different types of
interaction networks, for example, online social networks or animal transport networks. Several algorithms
have thus been introduced to build graphs according to
some predefined conditions. In this paper, we present an
algorithm that generates spatial graphs with a given
degree sequence. In spatial graphs, nodes are located in
a space equiped with a metric. Our goal is to define a
graph in such a way that the nodes and edges are
positioned according to an underlying metric. More
particularly, we have constructed a greedy algorithm
that generates nodes proportional to an underlying
probability distribution from the spatial structure, and
then generates edges inversely proportional to the
Euclidean distance between nodes. The algorithm first
generates a graph that can be a multigraph, and then
corrects multiedges. Our motivation is in data privacy
for social networks, where a key problem is the ability to
build synthetic graphs. These graphs need to satisfy a set
of required properties (e.g., the degrees of the nodes) but
also be realistic, and thus, nodes (individuals) should be
located according to a spatial structure and connections
should be added taking into account nearness.
