Aiming at the problem of short network life caused by low energy adaptive clustering hierarchy（ LEACH） algorithm in election process of cluster head using the maximum transmitting power and without consider residual energy and quantity variation of cluster heads

an improved algorithm of self-adaptive power control and optimization clustering quantity is proposed. The new algorithm introduces virtual cell to divide nodes position

in order to adjust nodes transmitting power and dynamically optimize quantity of cluster heed in order to change the election mode of cluster head. Finally

solve the problem of uneven energy consumption. The simulation results suggest that in the election of cluster head and the use ratio of nodes energy the new algorithm is superior to the LEACH algorithm

which can effectively balance network energy consumption and prolong network lifecycle.
