Social Based Routing in Delay Tolerant Network?

Delay tolerant network (DTN) is a kind of network where there is no end to end connection. Hence, route establishment between source and destination is difficult and also message delivery in such network is difficult. Probabilistic delay tolerant network uses past encounter records to forward the data or to select the forwarder. Probabilistic routing has limited local view of the network. So, most of the time, it cannot select better forwarder to route the message. Epidemic routing floods the message into the network. It requires more network resources. In social based routing, each node possesses a social map of its surrounding social network to select the forwarder. Here we have focused on different routing techniques based on social behavior of the network to establish the route from source to destination.
