TDelay tolerant networks (DTNs) peculiarity is lack
of continuous connectivity. DTN must handle network
partitioning, long delays, and dynamic topology. Hence routing
in DTN is thus challenging in such networks. Social-based
approaches, which attempt to exploit social behaviors of DTN
nodes to make better routing decision are more promising than
pure community-based routing protocols. To improve routing
performance, these methods take advantages of positive social
characteristics such as community, centrality, similarity,
friendship and social energy to assist packet forwarding. DTN
routing protocols uses these social characteristics to improve
performance and efficiency.

Social-Based Routing
Social Characteristics
Social-based approaches are more promising than pure
opportunity-based routing protocols for DTNs since these
social-based approaches take advantages of relatively
stable characteristics (social properties) efficiently to
predict and deal with the dynamics of DTNs. Combining
multiple metrics may provide opportunities to improve the
overall performance of routing and hence can reduce
delay and better forwarding of packets.
