(1) A large number of researches have shown that many
complex networks in nature are not only the result from
internal forces, but also the result from external forces which
should not be ignored to form an entire complex network.
Node failure may not only occour by node energy depletion or
random attacks to them when sensor networks are in the
working progress, but also occour by external forces, such as
by the nature, when deployed. In this paper, a mechanism of
small probability of random damage has been added to the
formation of sensor networks
