| 摘 要： | 针对机会传感网络基于节点移动实现网络通信的特点，考虑到影响移动节点连通度的因素，提出了机会传感网络的移动节点连通度模型，实现了对移动节点连通度的刻画.在区域划分的机会传感网络中，分析了移动节点时间序列特征因子，得到与特征因子相关的影响移动节点连通度的因素.利用一元回归得到影响因素与时延的关系，通过回归组合分析得到移动节点的连通度模型.仿真结果表明，该模型能够反映机会传感网络移动节点的连通度.

| Abstract: | According to the features of network communication through node movement in opportunistic sensor networks, a mobile node connectivity model was proposed by studying their impact factors, which dipicts connectivity of mobile nodes. In region-divided opportunistic sensor networks, the time series char-acteristic factors of mobile nodes were analyzed, and connectivity factors, related with them, were ob-tained. Monadic regression was employed to get the relationship between impact factors and delay. Based on the regression combination analysis, the mobile node connectivity model was constructed. Simulations show that the model can reflect the mobile node connectivity. |
