Self-organized wireless sensor networks(WSN)usually emerge with complex topology structure and high connectivity.Based on maximal independent sets' theory and the WSN's running requirements,the paper proposed a novel distributed network segmentation algorithm to achieve the monitor data transmitting requirements in the kind of uncontrolled centre WSN,in which each node's residual energy and the connectivity are defined a compound measure.Analyzed with computer simulation,the monitor grids are configured steadily,the maximum minimum grid's mean square deviation is decreased from 9.0667 to 3.7619,with which the efficiency of data aggregation is increased;the average transmission distance is decreased 13% to improve the operation stability.
