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 characteristic factors of mobile nodes were analyzed, and connectivity factors, related with them, were obtained.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.

Key words: opportunistic sensor networks, mobile nodes, connectivity factors, monadic regression analysis, regression combination analysis
