从一群移动的设备中收集数据是新兴的移动的传感系统的重要组成部分。在本文中，我们提出了一个有效的信息扩散协议的传感器数据收集通过机会网络。所提出的方法基于节点之间的无线电连通性的历史来检测行人组并且维持本地网络（即，簇）。通过与簇成员协作执行邻居发现和链路管理，它提高了邻居发现的能量效率并最小化信息传递延迟。仿真结果表明，在相同的接触探测间隔下，该方法可使消息传递性能提高16%~ 83%.
Data collection from a crowd of mobile devices is an essential building block of emerging mobile sensing systems. In this paper, we propose an efficient information diffusion protocol for sensor data collection via an opportunistic network. The proposed method detects groups of pedestrians based on the history of radio connectivity between the nodes and maintains a local network (i.e., a cluster) among the detected group members. By collaboratively performing neighbor discovery and link management with the cluster members, it enhances energy-efficiency of the neighbor discovery and minimizes the information delivery delay. Simulation results show that the proposed method can improve the message delivery performance by 16%-83% with equivalent contact probing intervals.
