| 摘 要： | 为实现在具有社会特征的延迟容忍网络中消息的高效转发，提出了节点中心度感知方法，通过综合分析节点的活跃程度与消息处理能力来量化节点的中心性，进而提出了节点中心度感知的路由机制。与经典的Epidemic和同是基于节点中心度的CC路由机制的对比结果表明，所提出的路由机制能够较为显著地改善消息的投递率和负载率。

| Abstract: | In order to forward messages more efficiently in the social oriented Delay Tolerant Network (DTN), this paper proposed a way to be aware of nodes' centralities. This paper came up with a routing mechanism for the awareness of nodes' centralities through a comprehensive analysis of the level of activity and the capacity of handling messages which aimed at quantifying the nodes' centralities. The result shows that compared with the traditional Epidemic routing and Contact Counts (CC) routing which principle is still based on nodes' centrality, the routing mechanism this paper discussed can significantly improve the rate of the message delivery and the rate of the overhead. |
