Routing in Socially Selfish Delay Tolerant Networks

Existing routing algorithms for Delay Tolerant Networks (DTNs) assume that nodes are willing to forward packets for others. In the real world, however, most people are socially selfish; i.e., they are willing to forward packets for nodes with which they have social ties but not others, and such willingness varies with the strength of the social tie. Following the philosophy of design for user, authors propose a Social Selfishness Aware Routing (SSAR) algorithm to allow user selfishness and provide better routing performance in an efficient way.
