AB  - As the technology is developing, the issue of classification and clustering in wireless sensor
networks is becoming increasingly significant. In this direction, the algorithms of optimization inspired by the
nature have come to exist to promote the classic methods and they have already developed significantly. In this
study, a novel algorithm of optimization called imperialist competitive algorithm is introduced which it is not
a natural phenomenon but is a social-political phenomenon inspired by mankind. It divides such variables as
centrality, distance and residual energy of initial population into two groups of imperialist and colony and
begins the competition to be clustered in the wireless sensor networks. In this research, in order to make the
clustering more uniform and lower the energy consumption of network, a parameter of number of neighbor node
is recommended for this algorithm. By evaluation, it is revealed that this parameter improves network lifetime
by 4%.
