Delay/Disruption Tolerant Networks (DTNs) are self-organized wireless ad-hoc networks, where end-to-end connectivity can not be guaranteed and communications rely on the assumption that the nodes are willing to store-carry-and-forward bundles in an opportunistic way. However, this assumption would be easily violated due to the selfish nodes which are unwilling to consume precious wireless resources by serving as bundle relays. To apply conventional reputation based incentive schemes in DTNs is extraordinarily challenging due to the unique network characteristics. To tackle this issue, in this paper, the authors propose success, a secure user-centric and social-aware reputation based incentive scheme for DTNs.
