Compared with 3G, 4G and Wi-Fi, Delay-Tolerant Networking (DTN) can only have intermittent chance to transmit messages. Without a clear end-to-end path, routing a message in DTN to the destination is difficult. But in some particular case, it could be an advantage. People around the world have their personal habit and it will be projected on their social life. Therefore we use the social behavior as a foundation feature of our routing algorithm. We propose two new kinds of routing algorithms with our own trace file. On one hand, birds of a feather flock together, so people who have similar interests tend to go to the same places. In case of this, we combining the personal interests and the trace file to different buildings where each node locates, we propose the building-based routing algorithm. On the other hand, we think people who have similar interests hang out together more often, so we use the social relationship as a feature and propose social-based routing algorithm. In the end, we compare our algorithms with Epidemic, MaxProp and PRoPHET routing algorithms. The result shows that our algorithms outperform the others.
