Abstract: In order to solve the problem of unable to do data aggregation operation and the problem of unbalanced ener- gy consumption cased by the nonuniform clustering process in the LEACH protocol, an Adaptive Dynamic Uniform Clustering (ADUC) data aggregation algorithm is proposed. In the cluster construct phase of ADUC, the logic area di- vide mechanism and the cluster head energy optimize mechanism arc introduced to ensure the uniformity of cluster head distribution and the energy consumption balance of the network, in the data aggregation phase, the adaptive weighted mechanism is introduced to reduce the redundancy and errors of the monitoring data and control the amount of commu- nication packets. Simulation results prove that ADUC algorithm can not only improve the accuracy of monitoring data but also reduce more than 43. 1 0 0 energy consumption of the network.
