延迟/中断容忍网络（DTNs）是一种端到端连通性无法保证的无线自组织网络，其通信依赖于节点愿意以机会主义方式存储-携带-转发捆绑包的假设。然而，由于这些自私的节点不愿意通过充当捆绑中继来消耗宝贵的无线资源，这一假设很容易被违反。由于DTN独特的网络特性，DTN中的激励问题极具挑战性。针对这一问题，本文提出了一种新的以用户为中心、基于社会认知的DTN声誉激励方案--与传统的信誉方案依赖于相邻节点来监控流量并跟踪彼此的信誉不同，节点ID允许节点管理其信誉证据并在必要时展示其信誉。我们还定义了自我检查和社区检查的概念，以加快声誉建立，并允许节点对同一社区中的目标形成一致的意见，这是基于我们的社会度量转发意愿。性能仿真证明了该方案的安全性、有效性和高效性。
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 the nodes are willing tostore-carry-and-forwardbundles in an opportunistic way. However, this assumption would be easily violated due to theselfish nodeswhich are unwilling to consume precious wireless resources by serving as bundle relays. Incentive issue in DTNs is extraordinarily challenging due to the unique network characteristics. To tackle this issue, in this paper, we proposeMobiID, a noveluser-centricandsocial-awarereputation based incentive scheme for DTNs. Different from conventional reputation schemes which rely on neighboring nodes to monitor the traffic and keep track of each other’s reputation,MobiIDallows a node to manage its reputation evidence and show to demonstrate its reputation whenever necessary. We also define the concepts ofself-checkandcommunity-checkto speed up reputation establishment and allow nodes to form consensus views towards targets in the same community, which is based on our social metric by forwarding willingness. Performance simulation are given to demonstrate the security, effectiveness and efficiency of the proposed scheme.
