中文摘要： 在延迟容忍网络中，节点间的社会联系和行为随时间趋于稳定，有利于选择合适的中继节点和转发时机，近年来社会感知路由成为研究热点。然而现有社会感知路由在社会关系特征的准确识别、时间社区发现、自适应实时消息受控复制、自适应冗余消息副本消除等方面研究不充分。针对现有社会感知路由协议面临的挑战，本项目将研究节点间社会联系和行为特征的准确社会度量，提出目标节点感知的中心性度量；针对节点的社会自私性，提出相应的激励机制促使节点参与数据传输；针对社区的异构性和动态性，提出时间社区发现算法；针对消息副本的固定配额不能适应当前网络环境，提出基于上下文的自适应消息受控复制方法；针对冗余消息副本对网络的损害，提出基于免疫的自适应冗余消息副本抑制与消除机制。通过这一研究，本项目将设计出一系列适用不同场景和应用的高效自适应社会感知路由协议，为促进延迟容忍网络的发展和普及提供有力的理论和技术支持。

英文摘要： In Delay tolerant networks Different (DTNs), social ties and behaviors between nodes tend to be stable over time and understanding them can facilitate the choosing of best relay nodes and forwarding time. The social-aware routing protocol has become a hot research topic for routing in DTNs in recent years. However, studies of existing social-aware routing protocols are insufficient regarding to accurately identifying the characteristics of social relations, temporal community detection, adaptive message controlled replication and adaptive redundancy elimination. Facing these challenges of existing social-aware routing protocols, this project thoroughly studies accurate social metrics to identify the characteristics of social ties and behaviors between nodes. Based on that, we will propose a series of destination-aware centrality metrics. To deal with social selfishness of nodes, we will propose a stimulation scheme to promote selfish nodes to cooperate and transmit messages. Due to the heterogeneity and dynamics of communities, we will propose a temporal community detection algorithm. Since the fixed quota of message copies cannot adapt to the current network condition, we will propose a context-based adaptive message controlled replication method. As the redundant message copies are harmful to the network, we will propose an immunization-based adaptive redundancy elimination scheme. Through the study of this project, we will design a series of efficient adaptive social-aware routing protocols for diverse scenarios and applications respectively, which can provide significant theoretical and technical supports to advance and popularize DTNs.
