ResumoIn this paper,an adaptive distributed clustering routing protocol(ADCR) is proposed for wireless sensor networks.ADCR determines the current optimal cluster number adaptive through dispersion of node distribution and curvature change based on Nth-order nearest-neighbor theory when position of sensor node or network topology is changed.Furthermore,with the residual energy of sensor nodes,the optimal proportion of cluster head in network is calculated to elect the cluster head set according to optimal cluster number.Simultaneously,Hausdorff distance is introduced to adjust the initial rapid formation clusters.Simulation results have proved the efficiency of ADCR.It prolongs lifetime more than DT,LEACH and PEGASIS.
