摘　　要：间断连接无线网络中的节点具有极强的聚集特性,数据转发过程需要充分地考虑节点之间的社会关系。提出一种社会属性感知的数据分发策略,根据实时获取的多维网络状态参数,节点以分布式的方式估计其自身及其他节点的社会属性。进而确定数据携带节点与目的节点之间的关系,以最小化资源开销的方式实现数据转发。结果表明,与典型机制相比,所提出的数据转发策略具有较高的投递率和较低的延迟,有效地改善了网络性能。The nodes in the intermittent connection wireless network have the aggregation feature, the relation between nodes should be considered by the packet transmitting procedure. A social attributes aware data forwarding strategy in ICWN is proposed. According to the multiple parameters of network status, the social attribute of nodes is evaluated with the distribute manner; moreover, the relation between nodes is determined. Consequently, the packets are forwarded to their destination nodes. Results show that the packet delivery ratio and the delay can be optimized by proposed strategy.
