Abstract Tele-immersive 3D communications pose significant challenges in
networking research and request for efficient construction of overlay networks, to
guarantee the efficient delivery. In the last couple of years various overlay con-
struction methods have been subject to many research projects and studies. How-
ever, in most cases, the selection of the overlay nodes is mainly based on network
and geographic only criteria. In this topic chapter, we focus on the social interaction
of the participants and the way that social interaction could be taken into account
for the construction of a network multicasting overlay. More precisely, we mine
information from the social network structures and correlate it with network
characteristics to select the nodes that could potentially serve more than one
users, and thus contribute toward the overall network overlay optimization.

Introduction
Advances in computer graphics, computer vision, 3D capturing and reconstruction
and the combination of sensors and social networks show a path toward a 3D
immersive internet,
i.e.
the internet
that delivers tele-immersive experiences.
