We present a network model, in which the connection probability of
two nodes depends on the physical distance between them. In
this model, the typical small-world features demonstrated by the WS
model occur. The edge length distribution is shown to be in a
power law form, which is different from that derived from the
rewiring mechanism of the WS model. We believe that the present
network model provides a transparent picture for the physical
origin of small world behaviors of some realistic networks.
