In order to study node localization problem with high density of the local anchor node in network.A type of network model with crowded anchor is proposed.The anchor nodes are segmented in order of priority,and changed state between activation and sleep in order.Localization result is got by unknown node through averaging the position according to the active nodes in one group.Simulation results show that localization algorithm with sleep scheduling mechanism has greatly improved localization precision compared to the original DV-Hop.
