In this paper, the authors describe SANE, the first forwarding mechanism that combines the advantages of both social-aware and stateless approaches in pocket switched network routing. SANE is based on the observation - that they validate on real-world traces - that individuals with similar interests tend to meet more often. In their approach, individuals (network members) are characterized by their interest profile, a compact representation of their interests. Through extensive experiments, they show the superiority of social-aware, stateless forwarding over existing stateful, social-aware and stateless, social-oblivious forwarding. An important byproduct of their interest-based approach is that it easily enables innovative routing primitives, such as interestcasting.
