MobiID: A User-Centric and Social-Aware Reputation Based Incentive Scheme for Delay/Disruption Tolerant Networks

摘要: Delay/Disruption tolerant networks (DTNs) are wireless ad-hoc networks, where end-to-end connectivity can not be guaranteed and communications rely on the assumption that nodes willing to store-carry-and-forward bundles in an opportunistic way. However, this would easily violated due selfish which unwilling consume precious resources by serving as bundle relays. Incentive issue DTNs is extraordinarily challenging unique network characteristics. To tackle issue, paper, we propose MobiID, a novel user-centric social-aware reputation based incentive scheme for DTNs. Different from conventional schemes neighboring monitor traffic keep track of each other's reputation, MobiID allows node manage its evidence show demonstrate whenever necessary. We also define concepts self-check community-check speed up establishment allow form consensus views towards targets same community, our social metric forwarding willingness. Performance simulation given security, effectiveness efficiency proposed scheme.
